  getMethodCallSyntax in interface ScriptEngineFactoryobj - The name representing the object whose method is to be invoked. The
 name is the one used to create bindings using the put method of
 ScriptEngine, the put method of an ENGINE_SCOPE
 Bindings,or the setAttribute method
 of ScriptContext.  The identifier used in scripts may be a decorated form of the
 specified one.method - The name of the method to invoke.args - names of the arguments in the method call.public List<String> getMimeTypes()
javax.script.ScriptEngineFactoryScriptEngineManager class to implement its
 getEngineByMimetype method.getMimeTypes in interface ScriptEngineFactorypublic List<String> getNames()
javax.script.ScriptEngineFactoryScriptEngine, which may be used to
 identify the ScriptEngine by the ScriptEngineManager.
 For instance, an implementation based on the Mozilla Rhino Javascript engine might
 return list containing {"javascript", "rhino"}.getNames in interface ScriptEngineFactorypublic String getOutputStatement(String toDisplay)
javax.script.ScriptEngineFactory
 public String getOutputStatement(String toDisplay) {
      return "print(" + toDisplay + ")";
 }
 getOutputStatement in interface ScriptEngineFactorytoDisplay - The String to be displayed by the returned statement.public Object getParameter(String key)
javax.script.ScriptEngineFactory
 The values for these keys are the Strings returned by getEngineName,
 getEngineVersion, getLanguageName,
 getLanguageVersion for the first four keys respectively. For NAME, one of the Strings
 returned by getNames is returned.
 A reserved key, THREADING, whose value describes the behavior of the engine
 with respect to concurrent execution of scripts and maintenance of state is also defined.
 These values for the THREADING key are:
 
null - The engine implementation is not thread safe, and cannot
 be used to execute scripts concurrently on multiple threads.
 "MULTITHREADED" - The engine implementation is internally
 thread-safe and scripts may execute concurrently although effects of script execution
 on one thread may be visible to scripts on other threads.
 "THREAD-ISOLATED" - The implementation satisfies the requirements
 of "MULTITHREADED", and also, the engine maintains independent values
 for symbols in scripts executing on different threads.
 "STATELESS" - The implementation satisfies the requirements of
 "THREAD-ISOLATED".  In addition, script executions do not alter the
 mappings in the Bindings which is the engine scope of the
 ScriptEngine.  In particular, the keys in the Bindings
 and their associated values are the same before and after the execution of the script.
 getParameter in interface ScriptEngineFactorykey - The name of the parameternull if no
 value is assigned to the key.public String getProgram(String... statements)
javax.script.ScriptEngineFactory
 public String getProgram(String... statements) {
      String retval = "<?\n";

      }
      return retval += "?>";
 }
 getProgram in interface ScriptEngineFactorystatements - The statements to be executed.  May be return values of
  calls to the getMethodCallSyntax and getOutputStatement methods.public ScriptEngine getScriptEngine()
javax.script.ScriptEngineFactoryScriptEngine associated with this
 ScriptEngineFactory. A new ScriptEngine is generally
 returned, but implementations may pool, share or reuse engines.getScriptEngine in interface ScriptEngineFactoryScriptEngine instance.public ScriptEngine getScriptEngine(ClassLoader appLoader)
