Constructor Detail

### MultipleRecnoDataEntry

    public MultipleRecnoDataEntry()

  Construct an entry with no data. The object must be configured before use with the `MultipleEntry.setUserBuffer` method.

### MultipleRecnoDataEntry

    public MultipleRecnoDataEntry(byte[] data)

  Construct an entry with a given byte array. The offset is set to zero; the size is set to the length of the array. If null is passed, the object must be configured before use with the `MultipleEntry.setUserBuffer` method.

Parameters:
  `data` - Byte array wrapped by the entry.

### MultipleRecnoDataEntry

    public MultipleRecnoDataEntry(byte[] data,
                                  int offset,
                                  int size)

  Constructs a DatabaseEntry with a given byte array, offset and size.

Parameters:
  `data` - Byte array wrapped by the DatabaseEntry.
  `offset` - Offset in the first byte in the byte array to be included.
  `size` - Number of bytes in the byte array to be included.

Method Detail

### next

    public boolean next(DatabaseEntry recno,
                        DatabaseEntry data)

  Get the next record number/data pair in the returned set. This method may only be called after a successful call to a `Database` or `Cursor` get method with this object as the data parameter.

  When used with the Queue and Recno access methods, `data.getData()`will return `null` for deleted records.``

  Parameters:
    `recno` - an entry that is set to refer to the next record number in the returned set.

    `data` - an entry that is set to refer to the next data element in the returned set.

  Returns:
    indicates whether a value was found. A return of `false` indicates that the end of the set was reached.
