DD::Image::OpState Struct Reference

#include <OpState.h>

Public Member Functions
	OpState (Op *op)
	Special Op ctor retrieves the graph state stored in op.
bool	operator== (const OpState &b) const
	Only compare the states ignoring GeneralInfo contents.
void	resetStates ()
	Reset to defaults.
void	append (const OpState &b)
	Append input states to the current ones.
void	appendStates (const DD::Image::Hash &hash, bool hashAnimates, const DD::Image::Hash &versionHash)
	Append to both editVersion and context hashes and animating flag:

Public Attributes
Hash	opHash
	Hash for the Op's current OutputContext state.
bool	opHashAnimates
	Will the OutputContext hash likely vary in time?
Hash	editVersionHash
	Hash for the Op's 'edit version'.
Hash	topologyHash
	Topology state of the graph, unaffected by knobs.
GeneralInfo	opInfo
	Info for the Op.

Detailed Description

For passing to Op state updating methods and stored in the inputs list of an Op. This is data flowing down the Op graph which may need to be manipulated by nodes other than the one that generated the Op, for example FrameHold and TimeOffset.
