minijava.translate
Class PigletResult

java.lang.Object
  minijava.translate.PigletResult

public final class PigletResult
extends java.lang.Object

A wrapper class that packages the objects returned by a visit method of the translator. Depending on what is being translated, a visit may return to its caller the expression subtree of the Piglet code in generation as well as the temporary that it assigns the expression to. If, in translating the expression, an expression is assigned to a temporary, its temporary number is described in result. Otherwise, it is null. (Note: the current use of this wrapper is only for its node, MiniJava expression subtree only yields Piglet expression subtree. No side effect is involved, so the temporary field of the wrapper is ignored.)
