void CVC3::Scope::restore

[inline, inherited]

Restore all the values.

Referenced by CVC3::Context::pop().

CVC3::ContextObj::ContextObj	(	Context *	context,
		bool	atBottomScope = true
	)			[inline, inherited]

Create a new ContextObj.

The initial scope is set to the bottom scope by default, to reduce the work of pop() (otherwise, if the object is defined only on a very high scope, its scope will be moved down with each pop). If 'atBottomScope' == false, the scope is set to the current scope.
