[internal] An implementation of xiiTypedEnumProperty that accesses the enum property data directly.

Member Function Documentation

GetPropertyPointer()

template<typename Class, typename EnumType, typename Type>

virtual void * xiiEnumMemberProperty< Class, EnumType, Type >::GetPropertyPointer ( const void * pInstance ) const

inlineoverridevirtual

Returns a pointer to the property data or nullptr. If a valid pointer is returned, that pointer and the information from GetSpecificType() can be used to step deeper into the type (if required).

You need to pass the pointer to an object on which you are operating. This function is mostly of interest when the property itself is a compound type (a struct or class). If it is a simple type (int, float, etc.) it doesn't make much sense to retrieve the pointer.

For example GetSpecificType() might return that a property is of type xiiVec3. In that case one might either stop and just use the code to handle xiiVec3 types, or one might continue and enumerate all sub-properties (x, y and z) as well.

Note

There is no guarantee that this function returns a non-nullptr pointer, independent of the type. When a property uses custom 'accessors' (functions to get / set the property value), it is not possible (or useful) to get the property pointer.

Implements xiiAbstractMemberProperty.

GetValue()

template<typename Class, typename EnumType, typename Type>

virtual xiiInt64 xiiEnumMemberProperty< Class, EnumType, Type >::GetValue ( const void * pInstance ) const

inlineoverridevirtual

Returns the value of the property. Pass the instance pointer to the surrounding class along.

Implements xiiAbstractEnumerationProperty.

SetValue()

template<typename Class, typename EnumType, typename Type>

virtual void xiiEnumMemberProperty< Class, EnumType, Type >::SetValue ( void * pInstance, xiiInt64 value ) const

inlineoverridevirtual

Modifies the value of the property. Pass the instance pointer to the surrounding class along.

Note

Make sure the property is not read-only before calling this, otherwise an assert will fire.

Implements xiiAbstractEnumerationProperty.
