Description

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

Method

ByteBuffergetSlice(ByteBuffer bb, int offset, int length)
Returns the subset of a byte buffer, using the given offset and length. 
if (length == 0) {
    return EMPTY;
ByteOrder order = bb.order();
bb = bb.duplicate();
bb.position(offset);
if (length > 0) {
    bb.limit(offset + length);
...
ByteBufferpreservingSlice(final ByteBuffer byteBuffer, final int position, final int limit)
Slice a portion of the ByteBuffer while preserving the buffers position and limit. 
final int savedPosition = byteBuffer.position();
final int savedLimit = byteBuffer.limit();
byteBuffer.limit(limit).position(position);
final ByteBuffer result = byteBuffer.slice();
byteBuffer.limit(savedLimit).position(savedPosition);
return result;
ByteBufferslice(ByteBuffer buf, int pos, int limit)
slice 
int oldPos = buf.position();
buf.position(pos);
ByteBuffer result = buf.slice();
result.limit(limit - pos);
buf.position(oldPos);
return result;
ByteBufferslice(ByteBuffer buf, int start, int end)
slice 
ByteBuffer b = buf.duplicate();
b.position(start);
b.limit(end);
return b.slice();
ByteBufferslice(ByteBuffer data)
slice 
if (data.hasRemaining()) {
    byte[] slice = new byte[data.remaining()];
    data.get(slice, 0, data.remaining());
    return ByteBuffer.wrap(slice);
return null;
ByteBufferslice(final ByteBuffer buffer, final int offset, final int length)
Slices a part of the specified ByteBuffer into a new byte buffer and returns it. 
final int oldPosition = buffer.position();
final int oldLimit = buffer.limit();
buffer.position(offset);
buffer.limit(offset + length);
final ByteBuffer slice = buffer.slice();
buffer.position(oldPosition);
buffer.limit(oldLimit);
return slice;
...
ByteBufferslice(final ByteBuffer buffer, final int position)
slice 
final ByteBuffer tmp = buffer.duplicate();
tmp.position(position);
return tmp.slice();
ByteBuffersliceBuffer(ByteBuffer byteBuffer, int start, int end)
slice Buffer 
int pos = byteBuffer.position();
int limit = byteBuffer.limit();
byteBuffer.position(start);
byteBuffer.limit(end);
ByteBuffer result = byteBuffer.slice();
byteBuffer.limit(limit);
byteBuffer.position(pos);
return result;
...
ByteBuffersliceByteBuffer(ByteBuffer buffer, int position, int length)
Creates a new ByteBuffer sliced from a given ByteBuffer. 
ByteBuffer slicedBuffer = ((ByteBuffer) buffer.duplicate().position(position)).slice();
slicedBuffer.limit(length);
return slicedBuffer;
ListsliceListBuffersPool(List buffersPool, int smallBufferSize, int buffersCount)

List<ByteBuffer> smallBuffers = new ArrayList<>();
for (ByteBuffer bigBuffer : buffersPool) {
    bigBuffer.rewind();
    while (bigBuffer.capacity() - bigBuffer.position() > smallBufferSize) {
        if (smallBuffers.size() == buffersCount) {
            return smallBuffers;
        bigBuffer.limit(bigBuffer.position() + smallBufferSize);
