public class Py2kBuffer extends PySequence implements BufferProtocol
buffer type. buffer is being superseded in
 Python 2.7 by memoryview, and is provided here to support legacy Python code. Use
 memoryview if you can.
 
 buffer and memoryview both wrap the same Jython buffer API:
 that designed for memoryview. In CPython, a new C API (which Jython's resembles) was
 introduced with memoryview. Because of this, buffer and
 memoryview may be supplied as arguments in the same places, and will accept as
 arguments the same (one-dimensional byte-array) types. Their behaviour differs as detailed in the
 documentation.

public Py2kBuffer(BufferProtocol object, int offset, int size)
BufferProtocol. The
 buffer takes no lease on the PyBuffer at present, but for each
 action performed obtains a new one and releases it. (Major difference from
 memoryview.) Note that when size=-1 is given, the buffer reflects
 the changing size of the underlying object.object - the object on which this is to be a buffer.offset - into the array exposed by the object (0 for start).size - of the slice or -1 for all of the object.public int __len__()

PyBuffer.release() on the buffer it
 obtained, since some objects alter their behaviour while buffers are exported.
 
 The PyBuffer returned from this method is provided directly by the underlying object
 on which this buffer was constructed, taking account of the slicing arguments (offset and
 size), if these were given when the buffer was constructed.

buffer to the given value, treating the
 operation as assignment to a slice of length one. This is different from the same operation
 on a byte array, where the assigned value must be an int: here it must have the buffer API
 and length one. This is an extension point called by PySequence in its implementation of
 PySequence.__setitem__(int, org.python.core.PyObject) It is guaranteed by PySequence that the index is within the bounds of
 the buffer. Any other clients calling pyset(int, PyObject) must make
