Method Detail

getLanguage

public ScriptLanguage getLanguage()

Gets the scripting language of the script.

setLanguage

public void setLanguage(ScriptLanguage scriptLanguage)

Overrides the script language to use when executing the script.

setOutputWriter

public void setOutputWriter(Writer output)

Sets the writer used to record the standard output stream.

public void setErrorWriter(Writer error)

Sets the writer used to record the standard error stream.

getEngine

public ScriptEngine getEngine()

Gets the script engine used to execute the script.

getReturnValue

public Object getReturnValue()

Gets the return value of the script.

getInfo

public ScriptInfo getInfo()

Description copied from interface: Module

Gets metadata about this module.

Specified by:

getInfo in interface Module

run

public void run()

Specified by:

run in interface Runnable

context

public Context context()

Description copied from interface: Contextual

Gets the application context to which the object belongs.

Specified by:

context in interface Contextual

See Also:

Contextual.getContext()

getContext

public Context getContext()

Description copied from interface: Contextual

Gets the application context to which the object belongs, or null if Contextual.setContext(Context) has not yet been called on this object.

Specified by:

getContext in interface Contextual

See Also:

Contextual.context()

setContext

public void setContext(Context context)

Description copied from interface: Contextual

Sets the application context to which the object belongs.

Typically this method simply delegates to Context.inject(Object), and should be called only once to populate the context. Most contextual objects do not support later alteration of the context, and will throw IllegalStateException if this method is invoked again.

Specified by:

setContext in interface Contextual

Context.inject(Object), for an example of how to implement this interface
