Member Function Documentation

◆ operator()()

bool BFConnectNodes::operator() ( )

overridevirtual

This performs the operation. Returns true if success, false if fail.

Implements Reversible.

Here is the call graph for this function:

◆ undoOnlyMe()

void BFConnectNodes::undoOnlyMe ( )

overridevirtual

Undoes the operations done by this class but not children. This method should be overloaded by most derived classes.

Reimplemented from Reversible.
