com.ibm.wala.ssa.SSAInstruction

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

com.ibm.wala.cast.ir.ssa.AstLexicalWrite

public class AstLexicalWrite
extends AstLexicalAccess

A set of lexical writes. This instruction represents writes 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 use for each lexical write, and the call graph builder ensures that these value numbers are kept consistent as lexical uses and definitions are discovered during call graph construction.
