- All Implemented Interfaces:
Serializable
A buffer changed event describes how a buffer has changed. These events are
used in
IBufferChangedListener notifications.
For text insertions, getOffset is the offset
of the first inserted character, getText is the
inserted text, and getLength is 0.
For text removals, getOffset is the offset
of the first removed character, getText is null,
and getLength is the length of the text that was removed.
For replacements (including IBuffer.setContents),
getOffset is the offset
of the first replaced character, getText is the replacement
text, and getLength is the length of the original text
that was replaced.
When a buffer is closed, getOffset is 0, getLength
is 0, and getText is null.
