Method Detail

available

public int available()
              throws IOException

Deprecated.

Method is overridden to report number of bytes that can now be read from decoded data buffer, without reading bytes from the underlying stream. Never throws an exception; returns number of bytes available without further reads from underlying source; -1 if stream has been closed, or 0 if an actual read (and possible blocking) is needed to find out.

Throws:

IOException

readByte

public byte readByte()
              throws IOException

Deprecated.

Specified by:

readByte in class org.apache.lucene.store.DataInput

Throws:

       int offset,
       int length,
       boolean fullRead)
         throws IOException

IOException

readBytes

public void readBytes(byte[] b,
             int offset,
