Java Buffer which can tell if it's dirty

Java Buffer which can tell if it's dirty

Due to the existing structure of code, which looks like this:
// Read buffer (using ByteBuffer)
// Pass buffer to a remote method, which MIGHT write to it
// Write buffer back if dirty
I want that my buffer should be able to identify if it is written to (if
it's dirty). I didn't find any buffer implementation in java with a dirty
flag.
In all these cases my code is already passing around ByteBuffers, in order
to add this dirty flag should I:
- simply wrap the ByteBuffer implementation with dirty flag
- Write a class with underlying byte array, add dirty big and other
operations
(get/put int or long) and re-create the ByteBuffer by wrapping around
the byte array
- Extend the ByteBuffer class? (I'd be happy to implement the get/put but
there
are WAY TOO many methods to be implemented)
Also, what are the overheads of wrapping the ByteBuffer implementation?
