Method

ByteBuffercreateByteBuffer(int size)
create Byte Buffer 
totalsize += size;
return ByteBuffer.allocateDirect(size).order(ByteOrder.nativeOrder());
ByteBuffercreateByteBuffer(int size)
Create a direct byte buffer with the given size 
return ByteBuffer.allocateDirect(size).order(ByteOrder.nativeOrder());
ByteBuffercreateByteBufferOnHeap(int size)
Create a new ByteBuffer of the specified size. 
ByteBuffer buf = ByteBuffer.allocate(size).order(ByteOrder.nativeOrder());
buf.clear();
return buf;
ByteBuffercreateCopy(ByteBuffer buffer)
create Copy 
buffer.rewind();
ByteBuffer copy = ByteBuffer.allocate(buffer.limit());
copy.order(buffer.order());
copy.put(buffer);
return copy;
java.nio.ByteBuffercreateDirectByteBuffer(byte[] data)
create Direct Byte Buffer 
if (data == null) {
    return null;
java.nio.ByteBuffer buf = java.nio.ByteBuffer.allocateDirect((Byte.SIZE / 8) * data.length)
        .order(java.nio.ByteOrder.nativeOrder());
buf.clear();
buf.put(data);
buf.flip();
...
ByteBuffer[]createIconsFromBuffers(List byteBuffers)
create Icons From Buffers 
ByteBuffer[] icons = new ByteBuffer[byteBuffers.size()];
for (int i = 0; i < byteBuffers.size(); i++) {
    icons[i] = byteBuffers.get(i);
return icons;
InputStreamcreateInputStream(final ByteBuffer buf)
create Input Stream 
return new InputStream() {
    @Override
    public int read() throws IOException {
        if (!buf.hasRemaining()) {
            return -1;
        return buf.get() & 0xFF;
    @Override
    public int read(byte[] bytes, int off, int len) throws IOException {
        if (!buf.hasRemaining()) {
            return -1;
        len = Math.min(len, buf.remaining());
        buf.get(bytes, off, len);
        return len;
};
byte[]newByteArrayFromByteBuffer(ByteBuffer buf)
Creates a byte array from the given ByteBuffer, the position property of input ByteBuffer remains unchanged. 
final int length = buf.remaining();
byte[] bytes = new byte[length];
buf.duplicate().get(bytes, 0, length);
return bytes;
ByteBuffernewByteBuffer(int bufferSize, boolean direct)
new Byte Buffer 
if (direct) {
    return ByteBuffer.allocateDirect(bufferSize);
} else {
    return ByteBuffer.allocate(bufferSize);
ByteBuffernewByteBuffer(int len)
new Byte Buffer 
return ByteBuffer.allocateDirect(len).order(ByteOrder.nativeOrder());
