PrefixDumperConsole

public PrefixDumperConsole()

Method Detail

main

public static void main(java.lang.String[] args)

initialise

public void initialise()

Description copied from class: Console

sets up all the needed objects.

Overrides:

initialise in class Console

processEquation

public void processEquation(Node node)
                     throws JepException

Description copied from class: Console

Performs the required operation on a node. Typically evaluates the node and prints the value.

Overrides:

processEquation in class Console

Parameters:

node - Node representing expression

Throws:

JepException - if a Parse or evaluation error

printHelp

public void printHelp()

Description copied from class: Console

Print help message.

Overrides:

printHelp in class Console

testSpecialCommands

public Console.SPEC_ACTION testSpecialCommands(java.lang.String command)

Description copied from class: Console

Checks for special commands. For example a subclass may have a verbose mode switched on of off using the command

verbose on

This method can be used detected this input, perform required actions and skip normal processing by returning true. In general sub classes should call the superclass methods to test for special commands that class implements

Overrides:

testSpecialCommands in class Console

Returns:

SPEC_ACTION.CONTINUE - continue processing this equation, SPEC_ACTION.BREAK - stop processing this equation and get the next line of input, SPEC_ACTION.EXIT stop the program
