StreamType::ImplConstraint Class Reference

#include "steam/streamtype.hpp"

Description

Special case of an implementation type being only partially specified Besides requiring some aspect of the implementation type, there is the promise to fill in defaults to build a complete implementation type if necessary.

createFrame()

virtual DataBuffer* createFrame ( ImplConstraint const &  furtherConstraints ) const

pure virtual

Similarly create a impl type which complies to this constraint as well as to the additional constraints (e.g.

frame size). Create a new frame buffer of the resulting type
