Interface DefUseList

All Known Implementing Classes:

DefUseListImpl

public interface DefUseList

DefUseList interface DefUseList is used to map a def-node to corresponding DefUseChain. An instance of DefUseChain contains one def-node defining the value of a symbol and the list of use-nodes refering the symbol. An instance of DefUseList created by new DefUseListImpl(flowRoot, lSym) maps def-node defining lSym to corresponding DefUseChain, where lSym usually represents a variable. FlowAnalSym --> DefUSeList --> DefUseChain --> def-node defining the value of the symbol --> list of use-nodes refering the symbol --> DefUseChain ... An instance of DefUseList created by new DefUseListImpl(flowRoot) maps def-node to corresponding DefUseChain, where the def-node may not be restricted to define one paticular symbol, for example, the instance may map all def-nodes in a subprogram to corresponding DefUseChain irrespective of symbols.

DefUseChain	getDefUseChain(IR pDefNode) getDefUseChain Get DefUseChain having pDefNode as its define node in this DefUseList.
java.util.List	getDefUseChainList() getDefUseChain Get the list of DefUseChains in this DefUseList.
java.util.List	getDefUseChainListOfSym(FlowAnalSym pSym) Get the list of DefUseChains having pSym as its define node symbol.
void	print() print Print this DefUseList.
