QLExpressScriptEngine

public QLExpressScriptEngine(QLExpressScriptEngineFactory factory)

Creates a new instance of AbstractScriptEngine using a SimpleScriptContext as its default ScriptContext.

方法详细资料

eval

public Object eval(String script,
                   ScriptContext context)
            throws ScriptException

Causes the immediate execution of the script whose source is the String passed as the first argument. The script may be reparsed or recompiled before execution. State left in the engine from previous executions, including variable values and compiled procedures may be visible during this execution.

参数:

script - The script to be executed by the script engine.

context - A ScriptContext exposing sets of attributes in different scopes. The meanings of the scopes ScriptContext.GLOBAL_SCOPE, and ScriptContext.ENGINE_SCOPE are defined in the specification.

The ENGINE_SCOPE Bindings of the ScriptContext contains the bindings of scripting variables to application objects to be used during this script execution.

返回:

The value returned from the execution of the script.

抛出:

ScriptException - if an error occurs in script. ScriptEngines should create and throw ScriptException wrappers for checked Exceptions thrown by underlying scripting implementations.

NullPointerException - if either argument is null.

eval

public Object eval(Reader reader,
                   ScriptContext context)
            throws ScriptException

Same as eval(String, ScriptContext) where the source of the script is read from a Reader.

参数:

reader - The source of the script to be executed by the script engine.

context - The ScriptContext passed to the script engine.

返回:

The value returned from the execution of the script.

抛出:

ScriptException - if an error occurs in script.

NullPointerException - if either argument is null.

createBindings

public Bindings createBindings()

Returns an uninitialized Bindings.

返回:

A Bindings that can be used to replace the state of this ScriptEngine.

getFactory

public ScriptEngineFactory getFactory()

Returns a ScriptEngineFactory for the class to which this ScriptEngine belongs.

返回:

The ScriptEngineFactory

getRunner

public com.ql.util.express.ExpressRunner getRunner()
