Class ChannelInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable

    public class ChannelInputStream
    extends java.io.InputStream
    An input stream which reads from a stream source channel. All read operations are directly performed upon the channel, so for optimal performance, a buffering input stream should be used to wrap this class.
    Since:
    1.2
