/**
* Abstract implementation of a table rendering.
* <p>
* Clients should subclass from this class if they wish to provide a table
* rendering.
* </p>
* <p>
*
* The label of the rendering is constructed by retrieving the expression from
* <code>IMemoryBlockExtension</code>. For IMemoryBlock, the label is
* constructed using the memory block's start address.
*
* This rendering manages the change states of its memory bytes if the memory
* block does not opt to manage the change states. For IMemoryBlockExtension, if
* the memory block returns false when #supportsChangeManagement() is called,
* this rendering will calculate the change state for each byte when its content
* is updated. Clients may manages the change states of its memory block by
* returning true when #supportsChangeManagement() is called. This will cause
* this rendering to stop calculating the change states of the memory block.
* Instead it would rely on the attributes returned in the MemoryByte array to
* determine if a byte has changed. For IMemoryBlock, this rendering will manage
* the change states its content.
*
* When firing change event, be aware of the following: - whenever a change
* event is fired, the content provider for Memory View view checks to see if
* memory has actually changed. - If memory has actually changed, a refresh will
* commence. Changes to the memory block will be computed and will be shown with
* the delta icons. - If memory has not changed, content will not be refreshed.
* However, previous delta information will be erased. The screen will be
* refreshed to show that no memory has been changed. (All delta icons will be
* removed.)
*
* Please note that these APIs will be called multiple times by the Memory View.
* To improve performance, debug adapters need to cache the content of its
* memory block and only retrieve updated data when necessary.
* </p>
*
* @since 3.2
