Detailed Description

The different states of a compressor buffer.

dirty: The buffer is different from the contents on the disk. Only stream may read and write. This is the initial state of a freshly allocated buffer.

writing: The buffer will soon be written to disk. Stream and thread may only read.

reading: The buffer will soon change to reflect the contents on the disk. Only thread may read and write.

clean: The buffer is equal to the contents on the disk. Only stream may read and write.

dirty->writing/reading: When the buffer is sent from stream to thread. writing/reading->clean: When the thread is done. clean->dirty: When the stream has changed the contents of the buffer.
