Detailed Description

Identifies the context in which a computation happens. This context can be used to identify values logged during the computation. For more details, see the comment at the top of the file.

This class should be subclassed to implement specific contexts.

print_current_in_line()

virtual void blender::ComputeContext::print_current_in_line ( std::ostream & stream ) const

pure virtual

Print information about this specific context. This has to be implemented by each subclass.

print_stack()

void blender::ComputeContext::print_stack	(	std::ostream &	stream,
		StringRef	name ) const

Print the entire nested context stack.
