Member Function Documentation

◆ ClearData()

template<typename T >
void JLightweightDatabundleT< T >::ClearData ( )
overridevirtual

Implements JDatabundle.

◆ EnableGetAs()

template<typename T >
template<typename S >
void JLightweightDatabundleT< T >::EnableGetAs ( )

EnableGetAs generates a vtable entry so that users may extract the contents of this JFactoryT from the type-erased JFactory.

The user has to manually specify which upcasts to allow, and they have to do so for each instance. It is recommended to do so in the constructor. Note that EnableGetAs<T>() is called automatically.

◆ GetSize()

template<typename T >
size_t JLightweightDatabundleT< T >::GetSize ( ) const
inlineoverridevirtual

Implements JDatabundle.
