Member Function Documentation

◆ operator()()

bool BFClearLiveRangeUse::operator() ( )

virtual

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

Implements Reversible.

Definition at line 36 of file BFClearLiveRangeUse.cc.

                                      {
     backup = set_;
     set_.clear();
     return true;
 }

References backup, and set_.

◆ undoOnlyMe()

void BFClearLiveRangeUse::undoOnlyMe ( )

virtual

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

Reimplemented from Reversible.
