ScriptEngine.
Returns: The name of the supported language.

  Returns the version of the scripting language supported by this
ScriptEngine.
Returns: The version of the supported language.

  Returns a String which can be used to invoke a method of a Java object using the syntax of the supported scripting language.

  Returns a String which can be used to invoke a method of a Java object using the syntax of the supported scripting language. For instance, an implementaton for a Javascript engine might be;

 public String getMethodCallSyntax(String obj,
                                   String m, String... args) {
      String ret = obj;
      ret += "." + m + "(";
      for (int i = 0; i < args.length; i++) {
          ret += args[i];
          if (i == args.length - 1) {
              ret += ")";
          } else {
              ret += ",";
          }
      }
      return ret;
 }

Returns: The String used to invoke the method in the syntax of the scripting language.
Parameters:
- obj - 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.
- m - The name of the method to invoke.
- args - names of the arguments in the method call.

  Returns an immutable list of mimetypes, associated with scripts that can be executed by the engine.

  Returns an immutable list of mimetypes, associated with scripts that
can be executed by the engine. The list is used by the
ScriptEngineManager class to implement its
getEngineByMimetype method.
Returns: The list of mime types.

  Returns an immutable list of short names for the ScriptEngine, which may be used to identify the ScriptEngine by the ScriptEngineManager.

  Returns an immutable list of short names for the ScriptEngine, 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"}.

  Returns a String that can be used as a statement to display the specified String using the syntax of the supported scripting language.

  Returns a String that can be used as a statement to display the specified String using the syntax of the supported scripting language. For instance, the implementaton for a Perl engine might be;

 public String getOutputStatement(String toDisplay) {
      return "print(" + toDisplay + ")";
 }
 

Returns: The string used to display the String in the syntax of the scripting language.
Parameters:
- toDisplay - The String to be displayed by the returned statement.

  Returns the value of an attribute whose meaning may be implementation-specific.

  Returns the value of an attribute whose meaning may be implementation-specific. Keys for which the value is defined in all implementations are:

• ScriptEngine.ENGINE
• ScriptEngine.ENGINE_VERSION
• ScriptEngine.NAME
• ScriptEngine.LANGUAGE
• ScriptEngine.LANGUAGE_VERSION

The values for these keys are the Strings returned by getEngineName, getEngineVersion, getName, getLanguageName and getLanguageVersion respectively.

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.

Implementations may define implementation-specific keys.
Returns: The value for the given parameter. Returns null if no value is assigned to the key.
Parameters:
- key - The name of the parameter

  Returns A valid scripting language executable progam with given statements.

  Returns A valid scripting language executable progam with given statements. For instance an implementation for a PHP engine might be:

 public String getProgram(String... statements) {
      $retval = "<?\n";
      int len = statements.length;
      for (int i = 0; i < len; i++) {
          $retval += statements[i] + ";\n";
      }
      $retval += "?>";

 }
 

Returns: The Program
Parameters:
- statements - The statements to be executed. May be return values of calls to the getMethodCallSyntax and getOutputStatement methods.

  Returns an instance of the ScriptEngine associated with this ScriptEngineFactory.

  Returns an instance of the ScriptEngine associated with this
ScriptEngineFactory. A new ScriptEngine is generally
returned, but implementations may pool, share or reuse engines.
Returns: A new ScriptEngine instance.
