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 classConsole
-
processEquation
public java.lang.Object 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 classConsole
- Parameters:
node
- Node representing expression- Returns:
- The result of the calculation
- Throws:
JepException
- if a Parse or evaluation error
-
printHelp
public void printHelp()
Description copied from class:Console
Print help message.
-
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 commandverbose 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 classConsole
- Returns:
- SPEC_ACTION.CONTINUE - continue processing this equation, SPEC_ACTION.BREAK - stop processing this equation and get the next line of input, SPEC_ACTION.ALTERED - the input text has been altered, SPEC_ACTION.EXIT stop the program
- See Also:
Console.split(String)
