## Class Buffer

- java.lang.Object
- - org.gjt.sp.jedit.buffer.JEditBuffer
  - - org.gjt.sp.jedit.Buffer

-     public class Buffer
      extends JEditBuffer

  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:

  - Operations such as insert() and remove(), undo(), change Buffer data in a writeLock(), and must be called from the AWT thread.
  - When accessing the buffer from another thread, you must call readLock() before and readUnLock() after, if you plan on performing more than one read, 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.
