ScriptEngineManager JDK 1.6)

Constructors

public ScriptEngineManager ()

If the thread context ClassLoader can be accessed by the caller,
then the effect of calling this constructor is the same as calling
ScriptEngineManager(Thread.currentThread().getContextClassLoader()).
Otherwise, the effect is the same as calling ScriptEngineManager(null).
See Also: Thread.getContextClassLoader(),

public ScriptEngineManager (ClassLoader loader)

This constructor loads the implementations of ScriptEngineFactory visible to the given ClassLoader using the service provider mechanism.

If loader is null, the script engine factories that are bundled with the platform and that are in the usual extension directories (installed extensions) are loaded.

This constructor loads the implementations of
ScriptEngineFactory visible to the given
ClassLoader using the service provider mechanism.

If loader is null, the script engine factories that are
bundled with the platform and that are in the usual extension
directories (installed extensions) are loaded.

Parameters:
- loader - ClassLoader used to discover script engine factories.

Methods

Hide/Show inherited methods

public Object get (String key)

Gets the value for the specified key in the Global Scope

public Bindings getBindings ()

getBindings returns the value of the globalScope field.

getBindings returns the value of the globalScope field.
ScriptEngineManager sets this Bindings as global bindings for
ScriptEngine objects created by it.
Returns: The globalScope field.

public ScriptEngine getEngineByExtension (String extension)

Look up and create a ScriptEngine for a given extension.

Look up and create a ScriptEngine for a given extension. The algorithm
used by getEngineByName is used except that the search starts
by looking for a ScriptEngineFactory registered to handle the
given extension using registerEngineExtension.
Returns: The engine to handle scripts with this extension. Returns null if not found.
Parameters:
- extension - The given extension
Throws:
- NullPointerException - if extension is null.

public ScriptEngine getEngineByMimeType (String mimeType)

Look up and create a ScriptEngine for a given mime type.

Look up and create a ScriptEngine for a given mime type. The algorithm
used by getEngineByName is used except that the search starts
by looking for a ScriptEngineFactory registered to handle the
given mime type using registerEngineMimeType.
Returns: The engine to handle scripts with this mime type. Returns null if not found.
Parameters:
- mimeType - The given mime type
Throws:
- NullPointerException - if mimeType is null.

public ScriptEngine getEngineByName (String shortName)

Looks up and creates a ScriptEngine for a given name.

Looks up and creates a ScriptEngine for a given name.
The algorithm first searches for a ScriptEngineFactory that has been
registered as a handler for the specified name using the registerEngineName
method.

If one is not found, it searches the array of ScriptEngineFactory instances
stored by the constructor for one with the specified name. If a ScriptEngineFactory
is found by either method, it is used to create instance of ScriptEngine.
Returns: A ScriptEngine created by the factory located in the search. Returns null if no such factory was found. The ScriptEngineManager sets its own globalScope Bindings as the GLOBAL_SCOPE Bindings of the newly created ScriptEngine.
Parameters:
- shortName - The short name of the ScriptEngine implementation. returned by the getNames method of its ScriptEngineFactory.
Throws:
- NullPointerException - if shortName is null.

public List<ScriptEngineFactory> getEngineFactories ()

Returns an array whose elements are instances of all the ScriptEngineFactory classes found by the discovery mechanism.

Returns an array whose elements are instances of all the ScriptEngineFactory classes
found by the discovery mechanism.
Returns: List of all discovered ScriptEngineFactorys.

public void put (String key, Object value)

Sets the specified key/value pair in the Global Scope.

public void registerEngineExtension (String extension, ScriptEngineFactory factory)

Registers a ScriptEngineFactory to handle an extension.

Registers a ScriptEngineFactory to handle an extension.
Overrides any such association found using the Discovery mechanism.
Parameters:
- extension - The extension type to be associated with the ScriptEngineFactory.
- factory - The class to associate with the given extension.
Throws:
- NullPointerException - if any of the parameters is null.

public void registerEngineMimeType (String type, ScriptEngineFactory factory)

Registers a ScriptEngineFactory to handle a mime type.

Registers a ScriptEngineFactory to handle a mime type.
Overrides any such association found using the Discovery mechanism.
Parameters:
- type - The mime type to be associated with the ScriptEngineFactory.
- factory - The class to associate with the given mime type.
Throws:
- NullPointerException - if any of the parameters is null.

public void registerEngineName (String name, ScriptEngineFactory factory)

Registers a ScriptEngineFactory to handle a language name.

Registers a ScriptEngineFactory to handle a language
name. Overrides any such association found using the Discovery mechanism.
Parameters:
- name - The name to be associated with the ScriptEngineFactory.
- factory - The class to associate with the given name.
Throws:
- NullPointerException - if any of the parameters is null.

public void setBindings (Bindings bindings)

setBindings stores the specified Bindings in the globalScope field.

setBindings stores the specified Bindings
in the globalScope field. ScriptEngineManager sets this
Bindings as global bindings for ScriptEngine
objects created by it.
Parameters:
- bindings - The specified Bindings
Throws:
- IllegalArgumentException - if bindings is null.
