Description

The list of methods to do ByteBuffer Split are organized into topic(s).

Method

List split(ByteBuffer buffer, byte tag)
Split buffer by tag

List<ByteBuffer> list = new ArrayList<ByteBuffer>();
byte[] srcArray = buffer.array();
trim(buffer, tag);
for (int i = 0, start = 0, end = 0; i < buffer.limit(); i++) {
 if (srcArray[i] != tag) {
 end = i;
 } else {
 int len = end - start + 1;
...

ByteBuffer split(ByteBuffer buffer, int position)
split

int bytesLength = position - buffer.position();
byte[] bytes = new byte[bytesLength];
buffer.get(bytes);
return ByteBuffer.wrap(bytes);

ByteBuffer[] split(ByteBuffer src, int unitSize)
split

int limit = src.limit();
if (unitSize >= limit) {
 return null;
int size = (int) (Math.ceil((double) src.limit() / (double) unitSize));
ByteBuffer[] ret = new ByteBuffer[size];
int srcIndex = 0;
for (int i = 0; i < size; i++) {
...

void splitLongToBuffers(ByteBuffer buffer, ByteBuffer buffer1, long iValue)
Split long value into two byte buffer.

int remaining = buffer.remaining();
int i;
for (i = 0; i < remaining; ++i) {
 buffer.put((byte) (iValue >> SIZE_OF_BYTE_IN_BITS * (SIZE_OF_LONG - i - 1)));
for (int j = 0; j < SIZE_OF_LONG - remaining; ++j) {
 buffer1.put((byte) (iValue >> SIZE_OF_BYTE_IN_BITS * (SIZE_OF_LONG - i - j - 1)));

void splitShortToBuffers(ByteBuffer buffer, ByteBuffer buffer1, short iValue)
Split short value into two byte buffer.

buffer.put((byte) (MASK & (iValue >>> SIZE_OF_BYTE_IN_BITS)));
buffer1.put((byte) (MASK & iValue));
