Member Function Documentation

◆ operator()()

bool BFInsertLiveRangeUse::operator() ( )

virtual

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

Implements Reversible.

Definition at line 36 of file BFInsertLiveRangeUse.cc.

                                       {
     if (set_.count(mnu_)) {
         return false;
     }
     set_.insert(mnu_);
     return true;
 }

References mnu_, and set_.

◆ undoOnlyMe()

void BFInsertLiveRangeUse::undoOnlyMe ( )

virtual

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

Reimplemented from Reversible.

Definition at line 45 of file BFInsertLiveRangeUse.cc.

                                       {
