Method Summary | |
public CompiledScript | compile(String script) Compiles the script (source represented as a String ) for later
execution.
Parameters: script - The source of the script, represented as aString . | public CompiledScript | compile(Reader script) Compiles the script (source read from Reader ) for later
execution. | public Bindings | createBindings() | public Object | eval(String script, ScriptContext scriptContext) | public Object | eval(Reader reader, ScriptContext scriptContext) | public ScriptEngineFactory | getFactory() | public T | getInterface(Class<T> clasz) Returns an implementation of an interface using procedures compiled in the
interpreter. | public T | getInterface(Object thiz, Class<T> clasz) Returns an implementation of an interface using member functions of a
scripting object compiled in the interpreter. | protected Interpreter | getInterpreter() | public Object | invoke(Object thiz, String name, Object... args) Calls a procedure compiled during a previous script execution, which is
retained in the state of the ScriptEngine.
Parameters: name - The name of the procedure to be called. Parameters: thiz - If the procedure is a member of a class defined in the scriptand thiz is an instance of that class returned by a previous execution orinvocation, the named method is called through that instance. | public Object | invoke(String name, Object... args) Same as invoke(Object, String, Object...) with null as the
first argument. |

compile | public CompiledScript compile(String script) throws ScriptException(Code) | | Compiles the script (source represented as a String ) for later
execution.
Parameters: script - The source of the script, represented as aString . An subclass of CompiledScript to be executed laterusing one of the eval methods of CompiledScript . throws: ScriptException - if compilation fails. throws: NullPointerException - if the argument is null. |
compile | public CompiledScript compile(Reader script) throws ScriptException(Code) | | Compiles the script (source read from Reader ) for later
execution. Functionality is identical to compile(String) other
than the way in which the source is passed.
Parameters: script - The reader from which the script source is obtained. An implementation of CompiledScript to be executedlater using one of its eval methods ofCompiledScript . throws: ScriptException - if compilation fails. throws: NullPointerException - if argument is null. |
getInterface | public T getInterface(Class<T> clasz)(Code) | | Returns an implementation of an interface using procedures compiled in the
interpreter. The methods of the interface may be implemented using the
invoke method.
Parameters: clasz - The Class object of the interface to return. An instance of requested interface - null if the requested interfaceis unavailable, i. e. if compiled methods in theScriptEngine cannot be found matching the ones in therequested interface. throws: IllegalArgumentException - if the specified Class objectdoes not exist or is not an interface. |
getInterface | public T getInterface(Object thiz, Class<T> clasz)(Code) | | Returns an implementation of an interface using member functions of a
scripting object compiled in the interpreter. The methods of the interface
may be implemented using invoke(Object, String, Object...) method.
Parameters: thiz - The scripting object whose member functions are used toimplement the methods of the interface. Parameters: clasz - The Class object of the interface to return. An instance of requested interface - null if the requestedinterface is unavailable, i. e. if compiled methods in theScriptEngine cannot be found matching the ones in therequested interface. throws: IllegalArgumentException - if the specified Class objectdoes not exist or is not an interface, or if the specified Object is nullor does not represent a scripting object. |
invoke | public Object invoke(Object thiz, String name, Object... args) throws ScriptException, NoSuchMethodException(Code) | | Calls a procedure compiled during a previous script execution, which is
retained in the state of the ScriptEngine.
Parameters: name - The name of the procedure to be called. Parameters: thiz - If the procedure is a member of a class defined in the scriptand thiz is an instance of that class returned by a previous execution orinvocation, the named method is called through that instance. If classes arenot supported in the scripting language or if the procedure is not a memberfunction of any class, the argument must be null . Parameters: args - Arguments to pass to the procedure. The rules for convertingthe arguments to scripting variables are implementation-specific. The value returned by the procedure. The rules for converting thescripting variable returned by the procedure to a Java Object areimplementation-specific. throws: javax.script.ScriptException - if an error occurrs during invocationof the method. throws: NoSuchMethodException - if method with given name or matching argumenttypes cannot be found. throws: NullPointerException - if method name is null. |
