template<class BaseType, class CoType>

ostream& operator<<	(	ostream &	out,
		const ABA_ACTIVE< BaseType, CoType > &	rhs
	)			[friend]

The output operator writes all active constraints and variables to an output stream. If an associated pool slot is void, or the item is newer than the one we refer to, then "void" is output.

Returns:

A reference to the output stream.

Parameters:

	out	The output stream.
	rhs	The active set being output.
