Examples of com.caucho.vfs.ReadStream

com.caucho.vfs.ReadStream
A fast bufferered input stream supporting both character and byte data. The underlying stream sources are provided by StreamImpl classes, so all streams have the same API regardless of the underlying implementation.
Dynamic streams, like tcp and http will properly flush writes before reading input. And random access streams, like RandomAccessFile, can use the same API as normal streams.
Most applications will use the Path routines to create their own streams. Specialized applications, like servers, need the capability of recycling streams.
