Method Detail

nextDef

public IR nextDef()

Description copied from interface: DefVectorIterator

nextDef: Get the next IR node that defines some symbol in the given DefVector (DefVector used to instanciate this iterator). Nodes that have 0 in the DefVector are skipped. If the last node is not a defining node, then null is returned at the last time. Therefore, having hasNext returned true does not guarantee this method returns meaningful (non-null) value.

Specified by:

nextDef in interface DefVectorIterator

nextSetRefRepr

public SetRefRepr nextSetRefRepr()

Description copied from interface: DefVectorIterator

Get the SetRefRepr that corresponds to the next bit that is on in this BitVector. This method returns the SetRefRepr object that wraps the node that will be returned by nextDef. If there is no SetRefReprs remaining, then returns null. Therefore, having hasNext returned true does not guarantee this method returns meaningful (non-null) value.
