## Member Function Documentation

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

Returns
  The number of references to this object.

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

virtual int asIScriptObject::CopyFrom | ( | asIScriptObject * | other | ) |
| pure virtual

Parameters

  [in] | other | A pointer to the source object.

Returns
  A negative value on error.

Return values

  asINVALID_ARG | The argument is null.
  asINVALID_TYPE | The other object is of different type.

This method copies the contents of the other object to this one.

virtual void* asIScriptObject::GetAddressOfProperty | ( | asUINT | prop | ) |
| pure virtual

Parameters

  [in] | prop | The property index.

Returns
  A pointer to the property value.

The method returns a pointer to the memory location for the property. Use the type id for the property to determine the content of the pointer, and how to handle it.

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

Returns
  The script engine.

virtual asITypeInfo* asIScriptObject::GetObjectType | ( |  | ) | const
| pure virtual

Returns
  The object type interface of the script object.

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

virtual asUINT asIScriptObject::GetPropertyCount | ( |  | ) | const
| pure virtual

Returns
  The number of member properties of the script object.

virtual const char* asIScriptObject::GetPropertyName | ( | asUINT | prop | ) | const
| pure virtual

Parameters

  [in] | prop | The property index.

Returns
  A null terminated string with the property name.

virtual int asIScriptObject::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 int asIScriptObject::GetTypeId | ( |  | ) | const
| pure virtual

Returns
  The type id of the script object.

virtual void* asIScriptObject::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 asILockableSharedBool* asIScriptObject::GetWeakRefFlag | ( |  | ) | const
| pure virtual

Returns
  The weak ref flag for the object.

This is a short-cut for the asIScriptEngine::GetWeakRefFlagOfScriptObject method.

virtual int asIScriptObject::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* asIScriptObject::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 script object 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 script object is destroyed.
