Class LitTable

java.lang.Object
  gnu.expr.LitTable

All Implemented Interfaces:

java.io.DataOutput, java.io.ObjectOutput

public class LitTable
extends java.lang.Object
implements java.io.ObjectOutput

Manages the literals of a Compilation. Implements ObjectOutput, because we use externalization to determine how literals get compiled into code that re-creates the literal.
