Description copied from interface: ContextDependent

Writes a stamp of the context into cache. Based on this stamp, a cache detects whether the context of this object has changed or not.

Specified by:

writeStamp in interface ContextDependent

Overrides:

writeStamp in class ContextDependentBase

Parameters:

cache - a cache entry to write the stamp

gs - the current graph state
