Method Details

process

public Node process(Node node,
 Node[] children)
             throws ParseException

Description copied from interface: CommandVisitorI

Performs the specified action on an expression tree.

Specified by:

process in interface CommandVisitorI

Parameters:

node - top node of the tree

children - the children of the node after they have been preprocessed.

Returns:

top node of the results.

Throws:

ParseException

init

public void init(Jep jep)

Description copied from interface: JepComponent

Initialize the component. This method is called whenever a component is added to Jep. Hence, it allows components to keep track of the other components they may rely on.

Specified by:

init in interface JepComponent

Parameters:

jep - the current Jep instance

getLightWeightInstance

public JepComponent getLightWeightInstance()

Description copied from interface: JepComponent

Gets a light-weight instance suitable for using in multiple threads.

Specified by:

getLightWeightInstance in interface JepComponent

Returns:

either a new instance, null or 'this'.
