## Member Function Documentation

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

Returns
  The number of references to this object.

Call this method when storing an additional reference to the object.

virtual bool asIObjectType::DerivesFrom | ( | const asIObjectType * | objType | ) | const
| pure virtual

Parameters

  [in] | objType | The potential parent type.

Returns
  True if the type inherits directly or indirectly from the informed type.

virtual asDWORD asIObjectType::GetAccessMask | ( |  | ) | const
| pure virtual

Returns
  The access mask for this type.

virtual asIObjectType* asIObjectType::GetBaseType | ( |  | ) | const
| pure virtual

Returns
  A pointer to the object type that this type derives from.

This method will only return a pointer in case of script classes that derives from another script class.

This does not increase the reference count of the returned object type.

virtual asIScriptFunction* asIObjectType::GetBehaviourByIndex | ( | asUINT | index,
|  | asEBehaviours * | outBehaviour
| ) |  | const
| pure virtual

Parameters

  [in] | index | The index of the behaviour.
  [out] | outBehaviour | Receives the type of the behaviour.

Returns
  The function of the behaviour, or null on error.

virtual asUINT asIObjectType::GetBehaviourCount | ( |  | ) | const
| pure virtual

Returns
  The number of behaviours for this type.

virtual const char* asIObjectType::GetConfigGroup | ( |  | ) | const
| pure virtual

Returns
  The name of the config group, or null if not set.

virtual asIScriptEngine* asIObjectType::GetEngine | ( |  | ) | const
| pure virtual

Returns
  A pointer to the engine.

virtual asIScriptFunction* asIObjectType::GetFactoryByDecl | ( | const char * | decl | ) | const
| pure virtual

Parameters

  [in] | decl | The declaration of the function

Returns
  The matching factory function or null if there are no matches

virtual asIScriptFunction* asIObjectType::GetFactoryByIndex | ( | asUINT | index | ) | const
| pure virtual

Parameters

  [in] | index | The index of the factory function.

Returns
  The factory function or null if the index is invalid.

virtual asUINT asIObjectType::GetFactoryCount | ( |  | ) | const
| pure virtual

Returns
  The number of factory functions for this object.

virtual asDWORD asIObjectType::GetFlags | ( |  | ) | const
| pure virtual

Returns
  A bit mask with the flags from asEObjTypeFlags.

Script classes are identified by having the asOBJ_SCRIPT_OBJECT flag set. Interfaces are identified as a script class with a size of zero.

  GetSize

virtual asIObjectType* asIObjectType::GetInterface | ( | asUINT | index | ) | const
| pure virtual

Parameters

  [in] | index | The interface index.

Returns
  A pointer to the interface type.

virtual asUINT asIObjectType::GetInterfaceCount | ( |  | ) | const
| pure virtual

Returns
  The number of interfaces implemented by this type.

virtual asIScriptFunction* asIObjectType::GetMethodByDecl | ( | const char * | decl,
|  | bool | getVirtual = `true`
| ) |  | const
| pure virtual

Parameters

  [in] | decl | The method signature.
  [in] | getVirtual | Set to true if the virtual method or the real method should be retrieved.

Returns
  The method or null on error.

This method should be used to retrieve the script method for the object that you wish to execute. The method is then sent to the context's Prepare method.

The method will find the script method with the exact same declaration.

virtual asIScriptFunction* asIObjectType::GetMethodByIndex | ( | asUINT | index,
|  | bool | getVirtual = `true`
| ) |  | const
| pure virtual

Parameters

  [in] | index | The index of the method.
  [in] | getVirtual | Set to true if the virtual method or the real method should be retrieved.

Returns
  The method or null on error.

This method should be used to retrieve the script method for the object that you wish to execute. The method is then sent to the context's Prepare method.

By default this returns the virtual method for script classes. This will allow you to call the virtual method on classes, and rely on the polymorphism to call the correct implementation. If you wish to inspect the real method, then you should set the second parameter to false to retrieve the real method.

virtual asIScriptFunction* asIObjectType::GetMethodByName | ( | const char * | name,
|  | bool | getVirtual = `true`
| ) |  | const
| pure virtual

Parameters

  [in] | name | The name of the method.
  [in] | getVirtual | Set to true if the virtual method or the real method should be retrieved.

Returns
  Tthe method or null in case of error

This method should be used to retrieve the script method for the object that you wish to execute. The method is then sent to the context's Prepare method.

virtual asUINT asIObjectType::GetMethodCount | ( |  | ) | const
| pure virtual

Returns
  The number of methods for this object.

virtual asIScriptModule* asIObjectType::GetModule | ( |  | ) | const
| pure virtual

| pure virtual

Returns
  A null terminated string with the name of the object type.

virtual const char* asIObjectType::GetNamespace | ( |  | ) | const

|  | int * | offset = `0`,
|  | bool * | isReference = `0`,
|  | asDWORD * | accessMask = `0`
| ) |  | const
| pure virtual

Parameters

Returns
  The number of bytes necessary to store instances of this type.

| pure virtual

Parameters

  [in] | subTypeIndex | The zero based index of the template sub type.

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

Parameters

  [in] | type | An identifier used to identify which user data to get.

Returns
  The pointer to the user data.

virtual bool asIObjectType::Implements | ( | const asIObjectType * | objType | ) | const
| pure virtual

Parameters

  [in] | objType | The interface type.

Returns
  True if the type implements the informed interface type.

virtual int asIObjectType::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.

virtual void* asIObjectType::SetUserData | ( | void * | data,
|  | asPWORD | type = `0`
| ) |  |
| pure virtual

Parameters

  [in] | data | A pointer to the user data.
  [in] | type | An identifier used to identify which user data to set.

Returns
  The previous pointer stored in the object type.

This method allows the application to associate a value, e.g. a pointer, with the object type instance. Multiple different values can be defined where the type argument identifies which is referred to.

The user data types identifiers between 1000 and 1999 are reserved for use by official add-ons.

Optionally, a callback function can be registered to clean up the user data when the object type is destroyed.
