Detailed Description

Provide class metadata.Helper macro to map type hashes to names.

Each class handled by PROPERTY_MANAGER needs to be described using AddProperty(), AddTypeCast() and InheritsAfter() methods.

Enum types use a dedicated property type (PROPERTY_ENUM), define its possible values with ENUM_MAP class, then describe the type using macros:

DECLARE_ENUM_TO_WXANY (in header files)
IMPLEMENT_ENUM_TO_WXANY (in source files)
ENUM_TO_WXANY (most often used; combines DECLARE and IMPLEMENT macros, if there is no need to share the description using header files)

Once all classes are described, the property list must be build using Rebuild() method.

◆ TypeCast() [1/2]

const void * PROPERTY_MANAGER::TypeCast	(	const void *	aSource,

Cast a type to another type.

Used for correct type-casting of types with multi-inheritance. Requires registration of an appropriate converter (AddTypeCast).

Parameters

aSource	is a pointer to the casted object.
aBase	is aSource type identifier (obtained using TYPE_HASH()).
aTarget	is the desired type identifier (obtained using TYPE_HASH()).

Returns: Properly casted pointer of aTarget type. *
