Detailed Description

PragmaNamespace - This PragmaHandler subdivides the namespace of pragmas, allowing hierarchical pragmas to be defined.

Common examples of namespaces are "\#pragma GCC", "\#pragma STDC", and "\#pragma omp", but any namespaces may be (potentially recursively) defined.

FindHandler()

PragmaHandler * PragmaNamespace::FindHandler	(	StringRef	Name,
		bool	IgnoreNull = true
	)		const

FindHandler - Check to see if there is already a handler for the specified name.

If not, return the handler for the null name if it exists, otherwise return null. If IgnoreNull is true (the default) then the null handler isn't returned on failure to match.

If not, return the handler for the null identifier if it exists, otherwise return null. If IgnoreNull is true (the default) then the null handler isn't returned on failure to match.

getIfNamespace - If this is a namespace, return it.

This is equivalent to using a dynamic_cast, but doesn't require RTTI.
