All Implemented Interfaces:

ParserConstants, java.io.Serializable

class LHS

extends java.lang.Object

implements ParserConstants, java.io.Serializable

The left hand side in an assignment This is probably the most debatable design issue in bsh... Because of the way things started, the grammar splits on whether something is an LHS or not... The alternative would be to wrap all objects in bsh, rather than just carrying types that might be used in an assignment. Wrapping all objects, say, in a generalized BshObject type, would also provide a nice place to put all the reflection stuff, which is now static in bsh.Reflect
