public class MemoryCellViewer

extends java.awt.Canvas

An AWT component which shows the address and the content of an addressable unit of an AddressSpace. The address is shown as a hexadecimal number. The content is shown as a hex number and a bit pattern (by using the class MemoryView).

This component is an interactive one. If one clicks onto a cell of the bit pattern an ActionEvent is sent to all ActionListeners who have subcribed at this component.
