      +--com.sleepycat.bdb.bind.SimpleBuffer

All Implemented Interfaces:
  DataBuffer

public class SimpleBuffer
extends Object
implements DataBuffer

A simple data buffer implementation that allows using bindings for arbitrary data outside the context of a database.

Constructor Summary
`SimpleBuffer()` Creates a simple buffer with null data, an offset of zero and a length of zero.
`SimpleBuffer(byte[] data)` Creates a simple buffer with the given data with an offset of zero and a length equal to the length of the data array.
`SimpleBuffer(byte[] data, int offset, int length)` Creates a simple buffer with the given data, offset and length.

Method Summary
`void` `clearDataFormation()` Sets the formation associated with the data in this buffer to null.
`byte[]` `getDataBytes()` Returns the byte array of the data buffer.
`Object` `getDataFormation()` Returns the formation associated with the data in this buffer.
`int` `getDataLength()` Returns the byte length of the data in the array.
`int` `getDataOffset()` Returns the byte offset of the data in the array.
`void` `setData(byte[] data, int offset, int length)` Sets the data in this buffer to the given value.
`void` `setDataFormation(Object formation)` Sets the formation associated with the data in this buffer.

Constructor Detail

### SimpleBuffer

    public SimpleBuffer()

  Creates a simple buffer with null data, an offset of zero and a length of zero.

### SimpleBuffer

    public SimpleBuffer(byte[] data)

  Creates a simple buffer with the given data with an offset of zero and a length equal to the length of the data array.

Parameters:
  `data` - is the data array and must not be modified after this method is called.

### SimpleBuffer

    public SimpleBuffer(byte[] data,
                        int offset,
                        int length)

  Creates a simple buffer with the given data, offset and length.

Parameters:
  `data` - is the data array and must not be modified after this method is called.
  `offset` - is the byte offset of the data in the array.
  `length` - is the byte length of the data in the array.

Method Detail

### setData

    public void setData(byte[] data,
                        int offset,
                        int length)

  Description copied from interface: `DataBuffer`
  Sets the data in this buffer to the given value. The byte array given will be owned by this buffer object after this method is called and must not be modified thereafter. This method must clear the data formation for this buffer.

  Specified by:
    `setData` in interface `DataBuffer`
  Parameters:
    `data` - is the data array and must not be modified after this method is called.
    `offset` - is the byte offset of the data in the array.
    `length` - is the byte length of the data in the array.

### getDataBytes

    public byte[] getDataBytes()

  Description copied from interface: `DataBuffer`
  Returns the byte array of the data buffer. This array is owned by the buffer object and should not be modified.

  Specified by:
    `getDataBytes` in interface `DataBuffer`
  Returns:
    the byte array of the data buffer.

### getDataOffset

    public int getDataOffset()

  Description copied from interface: `DataBuffer`
  Returns the byte offset of the data in the array.

  Specified by:
    `getDataOffset` in interface `DataBuffer`
  Returns:
    the byte offset of the data in the array.

### getDataLength

    public int getDataLength()

  Description copied from interface: `DataBuffer`
  Returns the byte length of the data in the array.

  Specified by:
    `getDataLength` in interface `DataBuffer`
  Returns:
    the byte length of the data in the array.

### setDataFormation

    public void setDataFormation(Object formation)

  Description copied from interface: `DataBuffer`
  Sets the formation associated with the data in this buffer.

  Specified by:
    `setDataFormation` in interface `DataBuffer`
  Parameters:
    `formation` - is Object to set.

### getDataFormation

    public Object getDataFormation()

  Description copied from interface: `DataBuffer`
  Returns the formation associated with the data in this buffer.

  Specified by:
    `getDataFormation` in interface `DataBuffer`
  Returns:
    formation Object.

### clearDataFormation

    public void clearDataFormation()

  Description copied from interface: `DataBuffer`
  Sets the formation associated with the data in this buffer to null.

  Specified by:
    `clearDataFormation` in interface `DataBuffer`
