// This pipeline accumulates the data passed to it into a memory
// buffer. Each subsequent use of this buffer appends to the data
// accumulated so far. getBuffer() may be called only after calling
// finish() and before calling any subsequent write(). At that point,
// a dynamically allocated Buffer object is returned and the internal
// buffer is reset. The caller is responsible for deleting the
// returned Buffer.
//
// For this pipeline, "next" may be null. If a next pointer is
// provided, this pipeline will also pass the data through to it.
