Constructor Details

SimpleDirectBufferAllocator

public SimpleDirectBufferAllocator()

Create a SimpleDirectBufferAllocator with default queue capacity - 3

SimpleDirectBufferAllocator

public SimpleDirectBufferAllocator(int capacity)

Create a SimpleDirectBufferAllocator with specified queue capacity. Important! capacity - should not be too large, otherwise the RAM may run out after a few iterations of use.

Parameters:

capacity - - queue size

Method Details

allocateBuffer

@NonNull
public ByteBuffer allocateBuffer(int capacity)

The method returns a byte buffer of the required size from the buffer queue, or allocates a new buffer and returns it.

Specified by:

allocateBuffer in interface IDirectBufferAllocator

Parameters:

capacity - - required buffer size in bytes

Returns:

a new ByteBuffer or ByteBuffer from a queue with the specified size

retainBuffer

public void retainBuffer(@NonNull
 ByteBuffer buffer)

Retain a buffer to the buffers queue. This method should be called when the memory buffer is no longer needed for use.

Parameters:

buffer - - a buffer that needs to be returned back to the queue

clear

public void clear()

Clear the buffers queue
