public boolean dependsOnContext()

Description copied from interface: ContextDependent

Determines whether this object actually depends on context.

Specified by:

dependsOnContext in interface ContextDependent

Returns:

true iff this object depends on context

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
