## Member Function Documentation

virtual asIScriptEngine* asIObjectType::GetEngine | ( |  | ) | const`[pure virtual]`

Returns:
  A pointer to the engine.

virtual const char* asIObjectType::GetConfigGroup | ( |  | ) | const`[pure virtual]`

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

virtual const char* asIObjectType::GetName | ( |  | ) | const`[pure virtual]`

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

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 asUINT asIObjectType::GetSize | ( |  | ) | const`[pure virtual]`

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

Application registered reference types doesn't store this information, as the script engine doesn't allocate memory for these itself.

virtual int asIObjectType::GetInterfaceCount | ( |  | ) | const`[pure virtual]`

Returns:
  The number of interfaces implemented by this type.

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

Parameters:

  `[in]` | index | The interface index.

Returns:
  A pointer to the interface type.

virtual int asIObjectType::GetFactoryCount | ( |  | ) | const`[pure virtual]`

Returns:
  A negative value on error, or the number of factory functions for this object.

virtual int asIObjectType::GetFactoryIdByIndex | ( | int | index | ) | const`[pure virtual]`

Parameters:

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

Returns:
  A negative value on error, or the factory id.

Return values:

  | asINVALID_ARG | index is out of bounds.

virtual int asIObjectType::GetFactoryIdByDecl | ( | const char * | decl | ) | const`[pure virtual]`

Parameters:

  `[in]` | decl | The factory signature.

Returns:
  A negative value on error, or the factory id.

Return values:

  | asNO_FUNCTION | Didn't find any matching functions.
  | asINVALID_DECLARATION | decl is not a valid declaration.
  | asERROR | The module for the type was not built successfully.

The factory function is named after the object type and returns a handle to the object. Example:

     id = type->GetFactoryIdByDecl("object@ object(int arg1, int arg2)");

virtual int asIObjectType::GetMethodCount | ( |  | ) | const`[pure virtual]`

Returns:
  A negative value on error, or the number of methods for this object.

virtual int asIObjectType::GetMethodIdByIndex | ( | int | index | ) | const`[pure virtual]`

Parameters:

  `[in]` | index | The index of the method.

Returns:
  A negative value on error, or the method id.

Return values:

  | asINVALID_ARG | index is out of bounds.

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

virtual int asIObjectType::GetMethodIdByName | ( | const char * | name | ) | const`[pure virtual]`

Parameters:

  `[in]` | name | The name of the method.

Returns:
  A negative value on error, or the method id.

Return values:

  | asMULTIPLE_FUNCTIONS | Found multiple matching methods.
  | asNO_FUNCTION | Didn't find any matching method.

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

virtual int asIObjectType::GetMethodIdByDecl | ( | const char * | decl | ) | const`[pure virtual]`

Parameters:

  `[in]` | decl | The method signature.

Returns:
  A negative value on error, or the method id.

Return values:

  | asMULTIPLE_FUNCTIONS | Found multiple matching methods.
  | asNO_FUNCTION | Didn't find any matching method.
  | asINVALID_DECLARATION | decl is not a valid declaration.
  | asERROR | The module for the type was not built successfully.

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

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

virtual asIScriptFunction* asIObjectType::GetMethodDescriptorByIndex | ( | int | index | ) | const`[pure virtual]`

Parameters:

  `[in]` | index | The index of the method.

Returns:
  A pointer to the method description interface, or null if not found.

virtual int asIObjectType::GetPropertyCount | ( |  | ) | const`[pure virtual]`

Returns:
  The number of member properties of the script object.

virtual int asIObjectType::GetPropertyTypeId | ( | asUINT | prop | ) | const`[pure virtual]`

Parameters:

  `[in]` | prop | The property index.

Returns:
  The type id of the member property, or a negative value on error.

Return values:

  | asINVALID_ARG | prop is too large

virtual const char* asIObjectType::GetPropertyName | ( | asUINT | prop | ) | const`[pure virtual]`

Parameters:

  `[in]` | prop | The property index.

Returns:
  A null terminated string with the property name.

virtual int asIObjectType::GetPropertyOffset | ( | asUINT | prop | ) | const`[pure virtual]`

Parameters:

  `[in]` | prop | The property index.

Returns:
  The offset of the property in the memory layout.

virtual int asIObjectType::GetBehaviourCount | ( |  | ) | const`[pure virtual]`

Returns:
  The number of behaviours for this type.

virtual int 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 id of the behaviour.

Return values:

  | asINVALID_ARG | The index is too large.
