computeLexicalRef

public Map<CGNode, OrdinalSet<Pair<CGNode,String>>> computeLexicalRef()

Compute the lexical variables possibly read by each CGNode and its transitive callees. A lexical variable is represented as a pair (C,N), where C is the defining CGNode and N is the String name.

computeLexicalMod

public Map<CGNode, OrdinalSet<Pair<CGNode,String>>> computeLexicalMod()

Compute the lexical variables possibly modified by each CGNode and its transitive callees. A lexical variable is represented as a pair (C,N), where C is the defining CGNode and N is the String name.

scanNodeForLexReads

protected Collection<Pair<CGNode,String>> scanNodeForLexReads(CGNode n)

scanNodeForLexWrites

protected Collection<Pair<CGNode,String>> scanNodeForLexWrites(CGNode n)
