Class StatementEvaluator.Result

java.lang.Object
  edu.rice.cs.dynamicjava.interpreter.StatementEvaluator.Result

Enclosing class:

StatementEvaluator

public static class StatementEvaluator.Result
extends java.lang.Object

Wraps an RuntimeBindings and an optional value. Strictly speaking, statements can sometimes produce new bindings but should never have values. In practice, however, it's convenient to occasionally allow a statement to produce a value in order to have a result to show the user -- the value of a variable declaration, for example, may be that variable's value (depending on the Options used).
