Constructor Detail

BoundedSeekableByteChannelInputStream

public BoundedSeekableByteChannelInputStream(java.nio.channels.SeekableByteChannel channel,
                                             long size)

Method Detail

read

public int read()
         throws java.io.IOException

Specified by:

read in class java.io.InputStream

Throws:

java.io.IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException

Reads up to len bytes of data from the input stream into an array of bytes.

An attempt is made to read as many as len bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer.

This implementation may return 0 if the underlying SeekableByteChannel is non-blocking and currently hasn't got any bytes available.

Overrides:

read in class java.io.InputStream

Throws:

java.io.IOException

read

private int read(int len)
          throws java.io.IOException

Throws:

close

public void close()

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.InputStream
