Constructor Detail

• ObjectBuffer

  public ObjectBuffer()

Method Detail

• resetAndStart

  public Object[] resetAndStart()

  Method called to start buffering process. Will ensure that the buffer is empty, and then return an object array to start chunking content on

• resetAndStart

  public Object[] resetAndStart(Object[] base,
                                int count)

  Since:

  2.9

• appendCompletedChunk

  public Object[] appendCompletedChunk(Object[] fullChunk)

  Method called to add a full Object array as a chunk buffered within this buffer, and to obtain a new array to fill. Caller is not to use the array it gives; but to use the returned array for continued buffering.

  Parameters:

  fullChunk - Completed chunk that the caller is requesting to append to this buffer. It is generally chunk that was returned by an earlier call to resetAndStart() or appendCompletedChunk(java.lang.Object[]) (although this is not required or enforced)

  Returns:

  New chunk buffer for caller to fill

• completeAndClearBuffer

  public Object[] completeAndClearBuffer(Object[] lastChunk,
                                         int lastChunkEntries)

  Method called to indicate that the buffering process is now complete; and to construct a combined exactly-sized result array. Additionally the buffer itself will be reset to reduce memory retention.

  Resulting array will be of generic Object[] type: if a typed array is needed, use the method with additional type argument.

• completeAndClearBuffer

  public <T> T[] completeAndClearBuffer(Object[] lastChunk,
                                        int lastChunkEntries,
                                        Class<T> componentType)

  Type-safe alternative to completeAndClearBuffer(Object[], int), to allow for constructing explicitly typed result array.

  Parameters:

  componentType - Type of elements included in the buffer. Will be used for constructing the result array.

• completeAndClearBuffer

  public void completeAndClearBuffer(Object[] lastChunk,
                                     int lastChunkEntries,
                                     List<Object> resultList)

• initialCapacity

  public int initialCapacity()

  Helper method that can be used to check how much free capacity will this instance start with. Can be used to choose the best instance to reuse, based on size of reusable object chunk buffer holds reference to.

• bufferedSize

  public int bufferedSize()

  Method that can be used to check how many Objects have been buffered within this buffer.

• _reset

  protected void _reset()

• _copyTo

  protected final void _copyTo(Object resultArray,
                               int totalSize,
                               Object[] lastChunk,
                               int lastChunkEntries)
