  +--org.concord.util.script.ScriptObject

All Implemented Interfaces:

java.beans.BeanInfo

Direct Known Subclasses:

Expression, NameStack, Script, Statement

public class ScriptObject

extends java.lang.Object

implements java.beans.BeanInfo

The ScriptObject class is the base class of all the nodes in the semantic tree. It maintains the necessary global state for the interpreter such as the current script and stack frame. It also supports utility methods for looking up Java methods and constructors.
