Constructor Detail

MemoryWindow

public MemoryWindow(org.gnu.glade.LibGlade glade)

The MemoryWindow displays the information stored at various locations in memory, starting from the current program counter to a user-defined region. The information can be displayed from 4-bit to 64-bit values, and in binary, octal, decimal or hexadecimal format. The MemoryWindow is dynamically created through the MemoryWindowFactory.

Parameters:

glade - The glade file containing MemoryWindow widgets.

Method Detail

finishMemWin

public void finishMemWin(Proc proc)

Initializes the Glade file, the MemoryWindow itself, adds listeners and Assigns the Proc.

Parameters:

proc - The Proc to be examined by mw.

setObservable

public void setObservable(Observable o)

hasTaskSet

public boolean hasTaskSet()

Check to see if the task to be examined has already been set.

Returns:

False if myTask is null, True otherwise.

setIsRunning

public void setIsRunning(boolean running)

Set the sensitivity of this window and the formatting window.

Parameters:

running - True if the window is running, false otherwise.

setTask

public void setTask(Task myTask)

Set the task for this MemoryWindow to examine. Initializes the Disassembler we use to grab instructions from memory, as well as initialize values for critical members of this class. Also performs the first refresh and display of information.

Parameters:

myTask - The task to be examined.

addressAccessible

private boolean addressAccessible(long address)

return a boolean indicating whether or not this address is accessible.

Returns:

whether or not this address is accessible

resetTask

public void resetTask(Task task)

recalculate

public void recalculate()

Recalculate the memory information based on a new bitsize and/or radix, and then update the display.

resetPCAndList

private void resetPCAndList()

refreshList

private void refreshList()

Refresh and update the display of addresses and values from what is re-calculated and turned into BigIntegers.

rowAppend

public void rowAppend(long i,
                      org.gnu.gtk.TreeIter iter)

Helper function for calculating memory information and putting it into rows to be displayed. By default append rows to the end; occasionally prepend rows to the front.

Parameters:

i - The memory address from which information is read from and stored in the model as an Object.

iter - The row in the TreeView.

desensitize

private void desensitize()

resensitize

private void resensitize()

padBytes

private String padBytes(String s,
                        boolean littleEndian,
                        int diff)

Pad this byte string with zeroes so that it is of proper size.

Parameters:

s - The String to pad zeroes to.

littleEndian - The endianness of the binary string.

diff - Eight minus this many bits need to be added.

switchEndianness

private String switchEndianness(String toReverse,
                                boolean littleEndian)

Switch the endianness of a binary string

Parameters:

toReverse - The String to converted

littleEndian - The endianness of this binary string.

handleFromSpin

public void handleFromSpin(double val)

When the 'From' SpinBox is changed, update the displayed information accordingly.

Parameters:

val - The new value of the SpinBox.

handleToSpin

public void handleToSpin(double val)

When the 'To' SpinBox value is changed, update the displayed information accordingly.

Parameters:

val - The new value of the SpinBox.

handleSymbol

private void handleSymbol(String symbolName)

When the box is inputed a symbol, update the displayed information to the symbol.

Parameters:

symbolName -
