CompiledScript

extends Object
java.lang.Object
   ↳ javax.script.CompiledScript

Class Overview

Extended by classes that store results of compilations. State might be stored in the form of Java classes, Java class files or scripting language opcodes. The script may be executed repeatedly without reparsing.

Each 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 tne CompiledScript may visible during subsequent executions of scripts by the engine.

Public Methods

public abstract Object eval (ScriptContext context)

Executes the program stored in this CompiledScript object.

Parameters
context A ScriptContext that is used in the same way as the ScriptContext passed to the eval methods of ScriptEngine.
Returns
  • The value returned by the script execution, if any. Should return null if no value is returned by the script execution.
Throws
ScriptException if an error occurs.
NullPointerException if context is null.

public Object eval ()

Executes the program stored in the CompiledScript object. The default ScriptContext of the associated ScriptEngine is used. The effect of calling this method is same as that of eval(getEngine().getContext()).

Returns
  • The return value from the script execution
Throws
ScriptException if an error occurs.

public Object eval (Bindings bindings)

Executes the program stored in the CompiledScript object using the supplied Bindings of attributes as the ENGINE_SCOPE of the associated ScriptEngine during script execution. If bindings is null, then the effect of calling this method is same as that of eval(getEngine().getContext()).

. The GLOBAL_SCOPE Bindings, Reader and Writer associated with the default ScriptContext of the associated ScriptEngine are used.

Parameters
bindings The bindings of attributes used for the ENGINE_SCOPE.
Returns
  • The return value from the script execution
Throws
ScriptException if an error occurs.

public abstract ScriptEngine getEngine ()

Returns the ScriptEngine wbose compile method created this CompiledScript. The CompiledScript will execute in this engine.

Returns
  • The ScriptEngine that created this CompiledScript
