boolean	isEditable() Determines whether this column is editable by user.
void	setDebugValue(int location, Object value) Called when user sets a value to a cell in debug window.

Method Detail

getClassType

Class getClassType()

Gets class type of the column. Mostly the column type is java.lang.String, but for breakpoint columns should be used java.lang.Boolean class.

Returns:

Java type of this column

getTitle

String getTitle()

Gets name (title) of the column.

Returns:

title of this column

isEditable

boolean isEditable()

Determines whether this column is editable by user. For example, mnemonics column shouldn't be editable (if CPU doesn't support assembly in runtime), but breakpoint cells should.

Returns:

true if column (with all its cells) is editable, false otherwise

setDebugValue

void setDebugValue(int location,
                   Object value)

Called when user sets a value to a cell in debug window. This method should ensure proper changes in CPU's internal state, caused by this set. The main module calls this method only if the cell in debug window is editable by user (DebugColumn.isEditable()).

Parameters:

location - memory address (not row in debug table)

value - new value of the cell

getDebugValue

Object getDebugValue(int location)

Gets the value of a cell in debug window at specified position.

Parameters:

location - memory address (not row in debug table)

Returns:

value of the cell

getDefaultWidth

default int getDefaultWidth()

Get default width of the column. If it is not known, this method should return -1.

Returns:

default width of the column or -1 if it is not known
