public class DefaultDataBufferFactory extends Object implements DataBufferFactory
DataBufferFactory interface. Allows for
specification of the default initial capacity at construction time, as well
as whether heap-based or direct buffers are to be preferred.| Modifier and Type | Field and Description |
|---|---|
static int |
DEFAULT_INITIAL_CAPACITY
The default capacity when none is specified.
|
| Constructor and Description |
|---|
DefaultDataBufferFactory()
Creates a new
DefaultDataBufferFactory with default settings. |
DefaultDataBufferFactory(boolean preferDirect)
Creates a new
DefaultDataBufferFactory, indicating whether direct
buffers should be created by allocateBuffer() and
allocateBuffer(int). |
DefaultDataBufferFactory(boolean preferDirect,
int defaultInitialCapacity)
Creates a new
DefaultDataBufferFactory, indicating whether direct
buffers should be created by allocateBuffer() and
allocateBuffer(int), and what the capacity is to be used for
allocateBuffer(). |
| Modifier and Type | Method and Description |
|---|---|
DefaultDataBuffer |
allocateBuffer()
Allocate a data buffer of a default initial capacity.
|
DefaultDataBuffer |
allocateBuffer(int initialCapacity)
Allocate a data buffer of the given initial capacity.
|
DefaultDataBuffer |
join(List<? extends DataBuffer> dataBuffers)
Return a new
DataBuffer composed of the dataBuffers elements joined together. |

wrap(byte[] bytes)
Wrap the given
byte array in a DataBuffer. |
DefaultDataBuffer |
wrap(ByteBuffer byteBuffer)
Wrap the given
ByteBuffer in a DataBuffer. |

DataBuffer composed of the dataBuffers elements joined together.
Depending on the implementation, the returned buffer may be a single buffer containing all
data of the provided buffers, or it may be a true composite that contains references to the
buffers.
Note that the given data buffers do not have to be released, as they are released as part of the returned composite.
This implementation creates a single DefaultDataBuffer
to contain the data in dataBuffers.
