Method Summary

Modifier and Type	Method and Description
public DataBuffer	Returns: the allocated buffer allocateBuffer() Deprecated since 6.0. as of 6.0, in favor of `allocateBuffer(int)` Allocate a data buffer of a default initial capacity.
public DataBuffer	Returns: the allocated buffer allocateBuffer(int the initial capacity of the buffer to allocate initialCapacity) Allocate a data buffer of the given initial capacity.
public boolean	Returns: `true` if this factory allocates direct buffers; `false` otherwise isDirect() Indicates whether this factory allocates direct buffers (i.e. non-heap, native memory).
public DataBuffer	Returns: a buffer that is composed of the `dataBuffers` argument join(List<? extends DataBuffer> the data buffers to be composed dataBuffers) Return a new `DataBuffer` composed of the `dataBuffers` elements joined together.
public DataBuffer	Returns: the wrapped buffer wrap(ByteBuffer the NIO byte buffer to wrap byteBuffer) Wrap the given `ByteBuffer` in a `DataBuffer`.
public DataBuffer	Returns: the wrapped buffer wrap(byte[] the byte array to wrap bytes) Wrap the given `byte` array in a `DataBuffer`.

allocateBuffer	back to summary
public DataBuffer allocateBuffer() Deprecated since 6.0. as of 6.0, in favor of `allocateBuffer(int)` Allocate a data buffer of a default initial capacity. Depending on the underlying implementation and its configuration, this will be heap-based or direct buffer. Returns:DataBuffer the allocated buffer Annotations @Deprecated since:6.0

public DataBuffer allocateBuffer()

Deprecated

since 6.0.

as of 6.0, in favor of allocateBuffer(int)

Allocate a data buffer of a default initial capacity. Depending on the underlying implementation and its configuration, this will be heap-based or direct buffer.

Returns:DataBuffer

the allocated buffer

Annotations

@Deprecated
since:6.0

allocateBuffer	back to summary
public DataBuffer allocateBuffer(int initialCapacity) Allocate a data buffer of the given initial capacity. Depending on the underlying implementation and its configuration, this will be heap-based or direct buffer. Parameters initialCapacity:int the initial capacity of the buffer to allocate Returns:DataBuffer the allocated buffer

allocateBuffer

back to summary

public DataBuffer allocateBuffer(int initialCapacity)

Allocate a data buffer of the given initial capacity. Depending on the underlying implementation and its configuration, this will be heap-based or direct buffer.

Parameters

initialCapacity:int: the initial capacity of the buffer to allocate

Returns:DataBuffer

the allocated buffer

isDirect back to summary

isDirect	back to summary
public boolean isDirect() Indicates whether this factory allocates direct buffers (i.e. non-heap, native memory). Returns:boolean `true` if this factory allocates direct buffers; `false` otherwise Since 6.0

public boolean isDirect()

Indicates whether this factory allocates direct buffers (i.e. non-heap, native memory).

Returns:boolean: true if this factory allocates direct buffers; false otherwise
Since: 6.0

join back to summary

join	back to summary
public DataBuffer join(List<? extends DataBuffer> dataBuffers) Return a new `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. Parameters dataBuffers:List<? extends DataBuffer> the data buffers to be composed Returns:DataBuffer a buffer that is composed of the `dataBuffers` argument Since 5.0.3

public DataBuffer join(List<? extends DataBuffer> dataBuffers)

Return a new 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.

Parameters

dataBuffers:List<? extends DataBuffer>: the data buffers to be composed

Returns:DataBuffer

a buffer that is composed of the dataBuffers argument

Since

5.0.3

wrap back to summary

wrap	back to summary
public DataBuffer wrap(ByteBuffer byteBuffer) Wrap the given `ByteBuffer` in a `DataBuffer`. Unlike allocating, wrapping does not use new memory. Parameters byteBuffer:ByteBuffer the NIO byte buffer to wrap Returns:DataBuffer the wrapped buffer

public DataBuffer wrap(ByteBuffer byteBuffer)

Wrap the given ByteBuffer in a DataBuffer. Unlike allocating, wrapping does not use new memory.

Parameters

byteBuffer:ByteBuffer: the NIO byte buffer to wrap

Returns:DataBuffer

the wrapped buffer

wrap back to summary

wrap	back to summary
public DataBuffer wrap(byte[] bytes) Wrap the given `byte` array in a `DataBuffer`. Unlike allocating, wrapping does not use new memory. Parameters bytes:byte[] the byte array to wrap Returns:DataBuffer the wrapped buffer

public DataBuffer wrap(byte[] bytes)

Wrap the given byte array in a DataBuffer. Unlike allocating, wrapping does not use new memory.

Parameters

bytes:byte[]: the byte array to wrap

Returns:DataBuffer

the wrapped buffer
