allocateBuffer
Deprecated.Description copied from interface:DataBufferFactory
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.- Specified by:
allocateBuffer
in interfaceDataBufferFactory
- Returns:
- the allocated buffer
-
allocateBuffer
Description copied from interface:DataBufferFactory
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.- Specified by:
allocateBuffer
in interfaceDataBufferFactory
- Parameters:
initialCapacity
- the initial capacity of the buffer to allocate- Returns:
- the allocated buffer
-
wrap
Description copied from interface:DataBufferFactory
- Specified by:
wrap
in interfaceDataBufferFactory
- Parameters:
byteBuffer
- the NIO byte buffer to wrap- Returns:
- the wrapped buffer
-

- Parameters:
bytes
- the byte array to wrap- Returns:
- the wrapped buffer
-
wrap
-
join
Description copied from interface:DataBufferFactory
Return a newDataBuffer
composed of thedataBuffers
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.
- Specified by:
join
in interfaceDataBufferFactory
- Parameters:
dataBuffers
- the data buffers to be composed- Returns:
- a buffer that is composed of the
dataBuffers
argument
-
isDirect
public boolean isDirect()Description copied from interface:DataBufferFactory
Indicates whether this factory allocates direct buffers (i.e. non-heap, native memory).- Specified by:
isDirect
in interfaceDataBufferFactory
- Returns:
true
if this factory allocates direct buffers;false
otherwise
