Method Detail

main

public static void main(String[] args)

getName

public String getName()
Description copied from class: AbstractMarsToolAndApplication
Required MarsTool method to return Tool name. Must be defined by subclass.

Specified by:
getName in interface MarsTool
Specified by:
getName in class AbstractMarsToolAndApplication
Returns:
Tool name. MARS will display this in menu item.

addAsObserver

protected void addAsObserver()
Description copied from class: AbstractMarsToolAndApplication
Add this app/tool as an Observer of desired MIPS Observables (memory and registers). By default, will add as an Observer of the entire Data Segment in memory. Override if you want something different. Note that the Memory methods to add an Observer to memory are flexible (you can register for a range of addresses) but may throw an AddressErrorException that you need to catch. This method is called whenever the default "Connect" button on a MarsTool or the default "Assemble and run" on a stand-alone Mars app is selected. The corresponding NOTE: if you do not want to register as an Observer of the entire data segment (starts at address 0x10000000) then override this to either do some alternative or nothing at all. This method is also overloaded to allow arbitrary memory subrange.

Overrides:
addAsObserver in class AbstractMarsToolAndApplication

update

public void update(Observable ressource,
                   Object accessNotice)
Description copied from class: AbstractMarsToolAndApplication
Called when receiving notice of access to MIPS memory or registers. Default implementation of method required by Observer interface. This method will filter out notices originating from the MARS GUI or from direct user editing of memory or register displays. Only notices arising from MIPS program access are allowed in. It then calls two methods to be overridden by the subclass (since they do nothing by default): processMIPSUpdate() then updateDisplay().

Specified by:
update in interface Observer
Overrides:
update in class AbstractMarsToolAndApplication
Parameters:
ressource - the attached MIPS resource
accessNotice - AccessNotice information provided by the resource

reset

protected void reset()
Description copied from class: AbstractMarsToolAndApplication
Method that will be called each time the default Reset button is clicked. Use it to reset any data structures and/or GUI components. By default it does nothing.

Overrides:
reset in class AbstractMarsToolAndApplication

buildMainDisplayArea

protected JComponent buildMainDisplayArea()
Description copied from class: AbstractMarsToolAndApplication
Abstract method that must be instantiated by subclass to build the main display area of the GUI. It will be placed in the CENTER area of a BorderLayout. The title is in the NORTH area, and the controls are in the SOUTH area.

Specified by:
buildMainDisplayArea in class AbstractMarsToolAndApplication

getHelpComponent

protected JComponent getHelpComponent()
Description copied from class: AbstractMarsToolAndApplication
Override this method to provide a JComponent (probably a JButton) of your choice to be placed just left of the Close/Exit button. Its anticipated use is for a "help" button that launches a help message or dialog. But it can be any valid JComponent that doesn't mind co-existing among a bunch of JButtons.

Overrides:
getHelpComponent in class AbstractMarsToolAndApplication

updateSevenSegment

public void updateSevenSegment(int number,
                               char value)

updateHexaKeyboard

public void updateHexaKeyboard(char row)

updateOneSecondCounter

public void updateOneSecondCounter(char value)
