## Detailed Description

It is allowed to have multiple instances of script engines, but there is rarely a need for it. Even if the application needs to expose different interfaces to different types of scripts this can usually be accomplished through the use of configuration groups and access profiles.

## Member Function Documentation

virtual int asIScriptEngine::AddRef | ( |  | ) | const
| pure virtual

Returns
  The number of references to this object.

Call this method when storing an additional reference to the object. Remember that the first reference that is received from asCreateScriptEngine is already accounted for.

virtual void asIScriptEngine::AddRefScriptObject | ( | void * | obj,
|  | int | typeId
| ) |  |
| pure virtual

Deprecated:
  Since 2.27.0. Use asIScriptEngine::AddRefScriptObject(void *, const asIObjectType *) instead

virtual void asIScriptEngine::AddRefScriptObject | ( | void * | obj,
|  | const asIObjectType * | type
| ) |  |
| pure virtual

Parameters

  [in] | obj | A pointer to the object.
  [in] | type | The type of the object.

This calls the add ref method of the object to increase the reference count.

virtual void asIScriptEngine::AssignScriptObject | ( | void * | dstObj,
|  | void * | srcObj,
|  | int | typeId
| ) |  |
| pure virtual

Deprecated:
  Since 2.27.0. Use asIScriptEngine::AssignScriptObject(void *, void *, const asIObjectType *) instead

virtual void asIScriptEngine::AssignScriptObject | ( | void * | dstObj,
|  | void * | srcObj,
|  | const asIObjectType * | type
| ) |  |
| pure virtual

Parameters

  [in] | dstObj | A pointer to the destination object.
  [in] | srcObj | A pointer to the source object.
  [in] | type | The type of the objects.

This calls the assignment operator to copy the object from one to the other.

This only works for objects.

virtual int asIScriptEngine::BeginConfigGroup | ( | const char * | groupName | ) |
| pure virtual

Parameters

  [in] | groupName | The name of the configuration group

Returns
  A negative value on error

Return values

  asNAME_TAKEN | Another group with the same name already exists.
  asNOT_SUPPORTED | Nesting configuration groups is not supported.

Starts a new dynamic configuration group. This group can be setup so that it is only visible to specific modules, and it can also be removed when it is no longer used.

  Dynamic configurations

virtual int asIScriptEngine::ClearMessageCallback | ( |  | ) |
| pure virtual

Returns
  A negative value on error.

Call this method to remove the message callback.

virtual asIScriptContext* asIScriptEngine::CreateContext | ( |  | ) |
| pure virtual

Returns
  A pointer to the new script context.

This method creates a context that will be used to execute the script functions. The context interface created will have its reference counter already increased.

virtual asIScriptFunction* asIScriptEngine::CreateDelegate | ( | asIScriptFunction * | func,
|  | void * | obj
| ) |  |
| pure virtual

Parameters

  [in] | func | The object method
  [in] | obj | The object pointer

Returns
  The new delegate instance

virtual void* asIScriptEngine::CreateScriptObject | ( | int | typeId | ) |
| pure virtual

Deprecated:
  Since 2.27.0. Use asIScriptEngine::CreateScriptObject(const asIObjectType *) instead

virtual void* asIScriptEngine::CreateScriptObject | ( | const asIObjectType * | type | ) |
| pure virtual

Parameters

  [in] | type | The type of the object to create.

Returns
  A pointer to the new object if successful, or null if not.

This method is used to create a script object based on it's type id. The method will call the object type's default factory. If the object type doesn't have a default factory the call will fail and no object will be created.

Created objects will have their reference counter set to 1 so the application needs to release the pointer when it will no longer use it.

This only works for objects, for primitive types and object handles the method doesn't do anything and returns a null pointer.

virtual void* asIScriptEngine::CreateScriptObjectCopy | ( | void * | obj,
|  | int | typeId
| ) |  |
| pure virtual

Deprecated:
  Since 2.27.0. Use asIScriptEngine::CreateScriptObjectCopy(void *, const asIObjectType *) instead

virtual void* asIScriptEngine::CreateScriptObjectCopy | ( | void * | obj,
|  | const asIObjectType * | type
| ) |  |
| pure virtual

Parameters

  [in] | obj | A pointer to the source object.
  [in] | type | The type of the object.

Returns
  A pointer to the new object if successful, or null if not.

This method is used to create a copy of an existing object.

This only works for objects, for primitive types and object handles the method doesn't do anything and returns a null pointer.

virtual void* asIScriptEngine::CreateUninitializedScriptObject | ( | int | typeId | ) |
| pure virtual

Deprecated:
  Since 2.27.0. Use asIScriptEngine::CreateUninitializedScriptObject(const asIObjectType *) instead

virtual void* asIScriptEngine::CreateUninitializedScriptObject | ( | const asIObjectType * | type | ) |
| pure virtual

Parameters

  [in] | type | The type of the object to create.

Returns
  A pointer to the new object if successful, or null if not.

This method can only be used to create instances of script classes.

The returned object will only be initialized so far that there are no invalid pointers or references. The constructor of the script class will not be invoked.

If the script class has any registered types as members, the default constructor for those members will be executed.

This method is meant for objects that will be initialized manually by the application, e.g. when restoring a serialized object.

virtual int asIScriptEngine::DiscardModule | ( | const char * | module | ) |
| pure virtual

Parameters

  [in] | module | The name of the module

Returns
  A negative value on error

Return values

  asNO_MODULE | The module was not found.

Discards a module and frees its memory. Any pointers that the application holds to this module will be invalid after this call.

virtual int asIScriptEngine::EndConfigGroup | ( |  | ) |
| pure virtual

Returns
  A negative value on error

Return values

  asERROR | Can't end a group that hasn't been begun.

Ends the current configuration group. Once finished a config group cannot be changed, but it can be removed when it is no longer used.

virtual int asIScriptEngine::GarbageCollect | ( | asDWORD | flags = `asGC_FULL_CYCLE` | ) |
| pure virtual

Parameters

  [in] | flags | Set to a combination of the asEGCFlags.

Returns
  1 if the cycle wasn't completed, 0 if it was.

This method will free script objects that can no longer be reached. When the engine is released the garbage collector will automatically do a full cycle to release all objects still alive. If the engine is long living it is important to call this method every once in a while to free up memory allocated by the scripts. If a script does a lot of allocations before returning it may be necessary to implement a line callback function that calls the garbage collector during execution of the script.

It is not necessary to do a full cycle with every call. This makes it possible to spread out the garbage collection time over a large period, thus not impacting the responsiveness of the application.

virtual void asIScriptEngine::GCEnumCallback | ( | void * | reference | ) |
| pure virtual

Parameters

  [in] | reference | A pointer to the referenced object.

When processing the EnumReferences call the called object should call GCEnumCallback for each of the references it holds to other objects.

Returns
  The name of the typedef.

virtual asUINT asIScriptEngine::GetTypedefCount | ( |  | ) | const
| pure virtual

Returns
  The number of registered typedefs.

virtual int asIScriptEngine::GetTypeIdByDecl | ( | const char * | decl | ) | const
| pure virtual

Parameters

  [in] | decl | The declaration of the type.

Returns
  A negative value on error, or the type id of the type.

Return values

  asINVALID_TYPE | decl is not a valid type.

Translates a type declaration into a type id. The returned type id is valid for as long as the type is valid, so you can safely store it for later use to avoid potential overhead by calling this function each time. Just remember to update the type id, any time the type is changed within the engine, e.g. when recompiling script declared classes, or changing the engine configuration.

The type id is based on a sequence number and depends on the order in which the type ids are queried, thus is not guaranteed to always be the same for each execution of the application. The asETypeIdFlags can be used to obtain some information about the type directly from the id.

A base type yields the same type id whether the declaration is const or not, however if the const is for the subtype then the type id is different, e.g. string@ isn't the same as const string@ but string is the same as const string.

This method is only able to return the type id that are not specific for a script module, i.e. built-in types and application registered types. Type ids for script declared types should be obtained through the script module's GetTypeIdByDecl.

virtual void* asIScriptEngine::GetUserData | ( | asPWORD | type = `0` | ) | const
| pure virtual

Parameters

  [in] | type | An identifier specifying the user data to get.

Returns
  The pointer to the user data.

virtual asILockableSharedBool* asIScriptEngine::GetWeakRefFlagOfScriptObject | ( | void * | obj,
|  | const asIObjectType * | type
| ) |  | const
| pure virtual

Parameters

  [in] | obj | The object
  [in] | type | The object type

Returns
  The weak ref flag, if the object supports weak references.

The method doesn't increase the reference to the returned shared boolean.

virtual bool asIScriptEngine::IsHandleCompatibleWithObject | ( | void * | obj,

  [in] | objTypeId | The type id of the object.
  [in] | handleTypeId | The type id of the handle.

Returns
  Returns true if the handle type is compatible with the object type.

This method can be used to determine if a handle of a certain type is compatible with an object of another type. This is useful if you have a pointer to a object, but only knows that it implements a certain interface and now you want to determine if it implements another interface.

virtual int asIScriptEngine::NotifyGarbageCollectorOfNewObject | ( | void * | obj,
|  | asIObjectType * | type
| ) |  |
| pure virtual

Returns
  The sequence number of the added object, or a negative value on error.

Return values

  asINVALID_ARG | Either the object or the type is null

This method should be called when a new garbage collected object is created. The GC will then store a reference to the object so that it can automatically detect whether the object is involved in any circular references that should be released.

virtual int asIScriptEngine::RegisterGlobalProperty | ( | const char * | declaration,
|  | void * | pointer
| ) |  |
| pure virtual

Parameters

  [in] | declaration | The declaration of the global property in script syntax.

Use this method to register a global property that the scripts will be able to access as global variables. The property may optionally be registered as const, if the scripts shouldn't be allowed to modify it.

When registering the property, the application must pass the address to the actual value. The application must also make sure that this address remains valid throughout the life time of this registration, i.e. until the engine is released or the dynamic configuration group is removed.

virtual int asIScriptEngine::RegisterInterface | ( | const char * | name | ) |
| pure virtual

Parameters

  [in] | name | The name of the interface.

Returns
  A negative value on error.

Return values

  asINVALID_NAME | The name is null, or a reserved keyword.
  asALREADY_REGISTERED | An object type with this name already exists.
  asERROR | The name is not a proper identifier.
  asNAME_TAKEN | The name is already used elsewhere.

This registers an interface that script classes can implement. By doing this the application can register functions and methods that receives an asIScriptObject and still be sure that the class implements certain methods needed by the application.

virtual int asIScriptEngine::RegisterStringFactory | ( | const char * | datatype,
|  | const asSFuncPtr & | factoryFunc,
|  | asDWORD | callConv,
|  | void * | objForThiscall = `0`
| ) |  |
| pure virtual

Parameters

  [in] | datatype | The datatype that the string factory returns
  [in] | factoryFunc | The pointer to the factory function
  [in] | callConv | The calling convention of the factory function
  [in] | objForThiscall | The object pointer used for asCALL_THISCALL_ASGLOBAL.

Return values

  asNOT_SUPPORTED | The calling convention is not supported.
  asWRONG_CALLING_CONV | The function's calling convention doesn't match callConv.
  asINVALID_TYPE | The datatype is not a valid type.

Use this function to register a string factory that will be called when the virtual machine finds a string constant in an expression. The string factory function will receive two parameters, the length of the string constant in bytes and a pointer to the character data. The factory should return a value to a previously registered type that will represent the string. Example:

// Our string factory implementation
std::string StringFactory(unsigned int byteLength, const char *s)
{
return std::string(s, byteLength);
}
// Registering the string factory
int r = engine->RegisterStringFactory("string", asFUNCTION(StringFactory), asCALL_CDECL); assert( r >= 0 );

The example assumes that the std::string type has been registered as the string type, with RegisterObjectType.

virtual int asIScriptEngine::Release | ( |  | ) | const
| pure virtual

Returns
  The number of references to this object.

Call this method when you will no longer use the references that you own.

The application is responsible for releasing references to all other script objects before releasing its last reference to the engine. If this is not done, it is possible that memory leaks occur as the engine cannot free objects kept alive by the application.

virtual void asIScriptEngine::ReleaseScriptObject | ( | void * | obj,
|  | int | typeId
| ) |  |
| pure virtual

Deprecated:
  Since 2.27.0. Use asIScriptEngine::ReleaseScriptObject(void *, const asIObjectType *) instead

This calls the release method of the object to release the reference.

virtual int asIScriptEngine::RemoveConfigGroup | ( | const char * | groupName | ) |
| pure virtual

Parameters

  [in] | groupName | The name of the configuration group

Returns
  A negative value on error

Return values

  asCONFIG_GROUP_IS_IN_USE | The group is in use and cannot be removed.

| ) |  |
| pure virtual

Parameters

  [in] | callback | A pointer to the function
  [in] | type | An identifier specifying which user data the callback is to be used with.

The function given with this call will be invoked when the engine is destroyed if any user data has been registered with the engine.

The function is called from within the engine destructor, so the callback should not be used for anything but cleaning up the user data itself.

virtual void asIScriptEngine::SetFunctionUserDataCleanupCallback | ( | asCLEANFUNCTIONFUNC_t | callback | ) |
| pure virtual

Parameters

  [in] | callback | A pointer to the function

The function given with this call will be invoked when a function is destroyed if any user data has been registered with the function.

Returns
  A negative value for an error.

Return values

  asINVALID_ARG | One of the arguments is incorrect, e.g. obj is null for a class method.
  asNOT_SUPPORTED | The arguments are not supported, e.g. asCALL_GENERIC.

This method sets the callback routine that will receive compiler messages. The callback routine can be either a class method, e.g:

void MyClass::MessageCallback(const asSMessageInfo *msg);
r = engine->SetMessageCallback(asMETHOD(MyClass,MessageCallback), &obj, asCALL_THISCALL);

or a global function, e.g:

void MessageCallback(const asSMessageInfo *msg, void *param);
r = engine->SetMessageCallback(asFUNCTION(MessageCallback), param, asCALL_CDECL);

It is recommended to register the message callback routine right after creating the engine, as some of the registration functions can provide useful information to better explain errors.

virtual void asIScriptEngine::SetModuleUserDataCleanupCallback | ( | asCLEANMODULEFUNC_t | callback | ) |
| pure virtual

Parameters

  [in] | callback | A pointer to the function

The function given with this call will be invoked when the module is destroyed if any user data has been registered with the module.
