Method Detail

process

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

Pre-process command. Expands and simplifies the child.

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 methods 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 an new instance, or 'this'.
