Class CallableLocal

java.lang.Object
  com.judoscript.CallableLocal

All Implemented Interfaces:

Callable, Consts, Expr, XMLDumpable, Variable, java.io.Serializable, java.lang.Comparable

public class CallableLocal
extends java.lang.Object
implements Variable, Callable

This class is wraps a runtime-instance along with its script, and make it available to other scripts running in multiple threads, such JUSP pages. For each invocation, its global context is pushed onto the client's context stack.

Let's call the caller as a client, running in its context called RTC; the script object is called a server, running in its context of RGC. Parameters and return values are conceptually passed "by value".

Only server functions can be accessed. Try to refrain from using global variable as much possible, especially as server programs. When need to, treat the code as running in separate threads and enforce concurrency constraints wherever appropriate.
