Examples of org.gjt.sp.jedit.Buffer

org.gjt.sp.jedit.Buffer
A Buffer represents the contents of an open text file as it is maintained in the computer's memory (as opposed to how it may be stored on a disk).
In a BeanShell script, you can obtain the current buffer instance from the buffer variable.
This class does not have a public constructor. Buffers can be opened and closed using methods in the jEdit class.
This class is partially thread-safe, however you must pay attention to two very important guidelines:
- Changes to a buffer can only be made from the AWT thread.
- When accessing the buffer from another thread, you must grab a read lock if you plan on performing more than one call, to ensure that the buffer contents are not changed by the AWT thread for the duration of the lock. Only methods whose descriptions specify thread safety can be invoked from other threads.
