Method Details

getEngine

public JexlEngine getEngine()

Gives access to the underlying JEXL engine shared between all ScriptEngine instances.

Returns:

the shared underlying JEXL engine

public PrintWriter getErr()

Gives access to the engine scope error writer (defaults to System.err).

Returns:

the engine error writer

getIn

public Reader getIn()

Gives access to the engine scope input reader (defaults to System.in).

Returns:

the engine input reader

getLogger

public org.apache.commons.logging.Log getLogger()

Gives access to the engine logger.

Returns:

the JexlScriptEngine logger

getOut

public PrintWriter getOut()

Gives access to the engine scope output writer (defaults to System.out).
