com.ibm.wala.ssa.SSAInstruction

com.ibm.wala.cast.ir.ssa.AstLexicalAccess

com.ibm.wala.cast.ir.ssa.AstLexicalRead

public class AstLexicalRead
extends AstLexicalAccess

A set of lexical reads. This instruction represents reads of a set of variables that are defined by a pair of variable name and defining code body (i.e. a method or function). This instruction has one local value number definition for each lexical read, and the call graph builder ensures that these value numbers are kept consistent as lexical uses and definitions are discovered during call graph construction.
