public abstract class CompiledScript extends Object
CompiledScript is associated with a ScriptEngine -- A call to an eval
method of the CompiledScript causes the execution of the script by the
ScriptEngine. Changes in the state of the ScriptEngine caused by execution
of the CompiledScript may visible during subsequent executions of scripts by the engine.| Constructor and Description |
