public void readFully(byte[] b)

Overrides org.hsqldb.lib.HsqlByteArrayInputStream.readFully.

Implements java.io.DataInput.readFully.

Doc from java.io.DataInput.readFully.

Reads some bytes from an input stream and stores them into the buffer array b. The number of bytes read is equal to the length of b.

This method blocks until one of the following conditions occurs:

  • b.length bytes of input data are available, in which case a normal return is made.
  • End of file is detected, in which case an EOFException is thrown.
  • An I/O error occurs, in which case an IOException other than EOFException is thrown.

If b is null, a NullPointerException is thrown. If b.length is zero, then no bytes are read. Otherwise, the first byte read is stored into element b[0], the next one into b[1], and so on. If an exception is thrown from this method, then it may be that some but not all bytes of b have been updated with data from the input stream.

readIntback to summary
public int readInt()

Overrides org.hsqldb.lib.HsqlByteArrayInputStream.readInt.

Implements org.hsqldb.rowio.RowInputInterface.readInt, java.io.DataInput.readInt.

Doc from java.io.DataInput.readInt.

Reads four input bytes and returns an int value. Let a-d be the first through fourth bytes read. The value returned is: 

(((a & 0xff) << 24) | ((b & 0xff) << 16) |
 ((c & 0xff) <<  8) | (d & 0xff))
This method is suitable for reading bytes written by the writeInt method of interface DataOutput.

Reads eight input bytes and returns a long value. Let a-h be the first through eighth bytes read. The value returned is: 

(((long)(a & 0xff) << 56) |
 ((long)(b & 0xff) << 48) |
 ((long)(c & 0xff) << 40) |
 ((long)(d & 0xff) << 32) |
