Specified by:

isReadOnly in interface IRaba

add

public final int add(byte[] a)

Description copied from interface: IRaba

Append a byte[] value to the end of the logical byte[][] (optional operation).

Specified by:

add in interface IRaba

Parameters:

a - A value.

Returns:

The #of values in the logical byte[][] (postcondition).

add

public final int add(byte[] value,
                     int off,
                     int len)

Description copied from interface: IRaba

Append a byte[] value to the end of the logical byte[][] (optional operation).

Specified by:

add in interface IRaba

Parameters:

value - A value

off - The offset of the first byte to be copied.

len - The #of bytes to be copied.

Returns:

The #of values in the logical byte[][] (postcondition).

add

public final int add(DataInput in,
                     int len)
              throws IOException

Description copied from interface: IRaba

Append a byte[] value to the end of the logical byte[][] (optional operation).

Specified by:

add in interface IRaba

Parameters:

in - The input stream from which the byte[] will be read.

len - The #of bytes to be read.

Returns:

The #of values in the logical byte[][] (postcondition).

Throws:

IOException

set

public final void set(int index,
                      byte[] a)

Description copied from interface: IRaba

Set the byte[] value at the specified index (optional operation).

Specified by:

set in interface IRaba

Parameters:

index - The index in [0:IRaba.size()-1].

a - The byte[] value.

toString

public final String toString()

Overrides:

toString in class Object

iterator
