◆ mergeScopes()

QCString mergeScopes	(	const QCString &	leftScope,

Merges two scope parts together. The parts may (partially) overlap. Example1: A::B and B::C will result in A::B::C
Example2: A and B will be A::B
Example3: A::B and B will be A::B

Parameters

leftScope	the left hand part of the scope.
rightScope	the right hand part of the scope.

Returns: the merged scope.
