Constructor Detail

### MultipleKeyDataEntry

    public MultipleKeyDataEntry()

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

### MultipleKeyDataEntry

    public MultipleKeyDataEntry(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.

### MultipleKeyDataEntry

    public MultipleKeyDataEntry(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 key,
                        DatabaseEntry data)

  Get the next key/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.

  Parameters:
    `key` - an entry that is set to refer to the next key element 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.

### append

    public boolean append(byte[] key,
                          int koff,
                          int klen,
                          byte[] data,
                          int doff,
                          int dlen)
                   throws DatabaseException

  Append an entry to the bulk buffer.

  Parameters:
    `key` - an array containing the key to be added.
    `koff` - the position in the key array where the record starts.
    `klen` - the length of the record, in bytes, to be copied from the key array.
    `data` - an array containing the value to be added.
    `doff` - the position in the data array where the record starts.
    `dlen` - the length of the record, in bytes, to be copied from the data array.

  Returns:
    indicates whether there was space. A return of `false` indicates that the specified entry could not fit in the buffer.
  Throws:
    `DatabaseException`

### append

    public boolean append(DatabaseEntry key,
                          DatabaseEntry data)
                   throws DatabaseException

  Append an entry to the bulk buffer.

  Parameters:
    `key` - the key to be appended, using the offset and size specified in the `DatabaseEntry`.
    `data` - the value to be appended, using the offset and size specified in the `DatabaseEntry`.

  Returns:
    indicates whether there was space. A return of `false` indicates that the specified entry could not fit in the buffer.
  Throws:
    `DatabaseException`

### append

    public boolean append(byte[] key,
                          byte[] data)
                   throws DatabaseException

  Append an entry to the bulk buffer.

  Parameters:
    `key` - an array containing the key to be added.
    `data` - an array containing the value to be added.

  Returns:
    indicates whether there was space. A return of `false` indicates that the specified entry could not fit in the buffer.
  Throws:
    `DatabaseException`
