Description

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

Method

voidsetBytesAtOffset(ByteBuffer buffer, int offset, int length, byte[] data)
Given a java.nio.ByteBuffer set bytes in an absolute offset without altering its current position. 
synchronized (buffer) {
    int position = buffer.position();
    buffer.position(offset);
    buffer.put(data, 0, length);
    buffer.position(position);
ByteBuffersetCell(ByteBuffer buffer, int cellIndex, int cellbytes)
Positions the given buffer at the start of the specified cell. 
int position = cellIndex * cellbytes;
int limit = position + cellbytes;
buffer.limit(limit).position(position);
return buffer;
voidsetCreationTime(ByteBuffer buf, Date date)
Set the creation date. 
Calendar cal = Calendar.getInstance();
if (date != null)
    cal.setTime(date);
fillBufFromTime(buf, cal);
voidsetFree(int frameIx, int offset, boolean free, ByteBuffer[] frames)
set Free 
if (free) { 
    frames[frameIx].put(offset, (byte) (((frames[frameIx]).array()[offset]) | 0x80));
} else { 
    frames[frameIx].put(offset, (byte) (((frames[frameIx]).array()[offset]) & 0x7F));
voidsetLimIfNeeded(ByteBuffer bb, int lim)
To avoid useless/dangerous(concurrency) writes. 
if (bb.limit() != lim) {
    bb.limit(lim);
voidsetLong(ByteBuffer buffer, long data)
set Long 
assert (buffer.capacity() - buffer.position() >= 8);
buffer.put((byte) (data & 0x00000000000000ffl));
buffer.put((byte) ((data & 0x000000000000ff00l) >>> 8));
buffer.put((byte) ((data & 0x0000000000ff0000l) >>> 16));
buffer.put((byte) ((data & 0x00000000ff000000l) >>> 24));
buffer.put((byte) ((data & 0x000000ff00000000l) >>> 32));
buffer.put((byte) ((data & 0x0000ff0000000000l) >>> 40));
buffer.put((byte) ((data & 0x00ff000000000000l) >>> 48));
...
voidsetSByte(ByteBuffer buffer, byte data)
set S Byte 
assert (buffer.capacity() - buffer.position() >= 1);
buffer.put(data);
voidsetSInt(ByteBuffer buffer, int data)
set S Int 
assert (buffer.capacity() - buffer.position() >= 4);
buffer.put((byte) (data & 0x000000ffl));
buffer.put((byte) ((data & 0x0000ff00l) >> 8));
buffer.put((byte) ((data & 0x00ff0000l) >> 16));
buffer.put((byte) ((data & 0xff000000l) >> 24));
voidsetString(ByteBuffer buffer, int index)
set String 
byte[] data = new byte[buffer.capacity()];
for (int i = 0; i < data.length; i++) {
    data[i] = 'x';
String _index = "" + index;
byte[] __index = _index.getBytes();
for (int i = 0; i < __index.length; i++) {
    data[i] = __index[i];
...
voidsetString(ByteBuffer buffer, String data)
set String 
assert (null != data);
byte[] bytes = data.getBytes();
assert (buffer.capacity() - buffer.position() >= Array.getLength(bytes));
buffer.put(bytes);
buffer.put((byte) 0);
