Detailed Description

The base class for class members in the Meta repository.

Constructor & Destructor Documentation

MetaMember()

OGF::MetaMember::MetaMember	(	const std::string &	name,
		MetaClass *	container
	)

MetaMember constructor.

Parameters

[in]	name	name of the member
[in]	container	the MetaClass this MetaMember belongs to

Note

MetaMember's constructor does not automatically add the MetaMember to the container class, since MetaProperty has a getter and setter MetaMethods which are not directly contained by the MetaClass.

Member Function Documentation

name()

const std::string & OGF::MetaMember::name ( ) const

inline

Gets the name of this MetaMember.

Returns

a const reference to the name

Definition at line 79 of file meta_member.h.

pre_delete()

virtual void OGF::MetaMember::pre_delete ( )

virtual

Removes all variables that use the meta type system before deleting.

If we do not do that, when deleting the meta type system, we can delete the meta information in the wrong order, and delete first meta classes that we needed to delete other ones.

Reimplemented in OGF::DynamicMetaSlot, and OGF::MetaMethod.
