Examples of org.simpleframework.transport.Cursor

org.simpleframework.transport.Cursor
The Cursor object is used to acquire bytes from a given source. This provides a cursor style reading of bytes from a stream in that it will allow the reader to move the cursor back if the amount of bytes read is too much. Allowing the cursor to move ensures that excess bytes back be placed back in the stream.
This is used when parsing input from a stream as it ensures that on arrival at a terminal token any excess bytes can be placed back in to the stream. This allows data to be read efficiently in large chunks from blocking streams such as sockets. @author Niall Gallagher @see org.simpleframework.transport.TransportCursor
