Description

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

Method

voidwriteUB2(ByteBuffer buffer, int i)
write UB 
buffer.put((byte) (i & 0xff));
buffer.put((byte) (i >>> 8));
voidwriteUnsigned(int num, int size, ByteBuffer out)
write Unsigned 
for (int i = 0; i < size; i++) {
    out.put((byte) num);
    num >>>= 8;
voidwriteUnsignedInt(ByteBuffer buf, long value)
Marshall a long into the next 4 bytes in this buffer. 
buf.put((byte) (value >>> 0));
buf.put((byte) (value >>> 8));
buf.put((byte) (value >>> 16));
buf.put((byte) (value >>> 24));
voidwriteUnsignedInt(final ByteBuffer buffer, final long value)
Write the given long value as a 4 byte unsigned integer. 
buffer.putInt((int) (value & 0xffffffffL));
voidwriteUnsignedVarInt(int value, ByteBuffer dest)
write Unsigned Var Int 
while ((value & 0xFFFFFF80) != 0L) {
    dest.putInt((value & 0x7F) | 0x80);
    value >>>= 7;
dest.putInt(value & 0x7F);
voidwriteUTF8StringToByteBuffer(String str, ByteBuffer bb)
write UTF String To Byte Buffer 
Charset charset = Charset.forName("UTF-8");
CharsetEncoder encoder = charset.newEncoder();
CharBuffer in = CharBuffer.wrap(str);
try {
    encoder.encode(in, bb, true);
    return;
} catch (Exception e) {
    e.printStackTrace();
...
voidwriteUUID(ByteBuffer buffer, UUID uuid)
write UUID 
buffer.putLong(uuid.getMostSignificantBits());
buffer.putLong(uuid.getLeastSignificantBits());
voidwriteV(ByteBuffer byteBuffer, List vint)
write V 
if (vint == null)
    return;
byteBuffer.putInt(vint.size());
for (int i = 0; i < vint.size(); ++i) {
    byteBuffer.putInt(vint.get(i));
voidwriteVarint(int value, ByteBuffer buffer)
Write the given integer following the variable-length zig-zag encoding from Google Protocol Buffers into the buffer. 
int v = (value << 1) ^ (value >> 31);
while ((v & 0xffffff80) != 0L) {
    byte b = (byte) ((v & 0x7f) | 0x80);
    buffer.put(b);
    v >>>= 7;
buffer.put((byte) v);
voidwriteVarLong(ByteBuffer buff, long x)
Write a variable size int. 
while ((x & ~0x7f) != 0) {
    buff.put((byte) (0x80 | (x & 0x7f)));
    x >>>= 7;
buff.put((byte) x);
