Description

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

Method

voidputTriByte(ByteBuffer buf, int value)
Writes a 'tri-byte' to the specified buffer. 
buf.put((byte) (value >> 16));
buf.put((byte) (value >> 8));
buf.put((byte) value);
ByteBufferputTruncatedInt(ByteBuffer bytes, int value, int numBytes)
put Truncated Int 
if (numBytes <= 0)
    throw new IOException("too few bytes specified for truncated int value!");
else if (numBytes >= 4) {
    if (bytes.remaining() < 4)
        throw new IOException("not enough space in buffer to write truncated int value");
    return bytes.putInt(value);
if (bytes.remaining() < numBytes)
...
voidputUInt16(ByteBuffer buffer, long value)
put U Int 
byte first = (byte) ((value >> 8) & 0xff);
byte second = (byte) (value & 0xff);
if (buffer.order() == ByteOrder.LITTLE_ENDIAN) {
    buffer.put(first);
    buffer.put(second);
} else {
    buffer.put(second);
    buffer.put(first);
...
voidputUInt32(ByteBuffer buffer, long value)
put U Int 
byte first = (byte) ((value >> 24) & 0xff);
byte second = (byte) ((value >> 16) & 0xff);
byte third = (byte) ((value >> 8) & 0xff);
byte fourth = (byte) (value & 0xff);
if (buffer.order() == ByteOrder.LITTLE_ENDIAN) {
    buffer.put(first);
    buffer.put(second);
    buffer.put(third);
...
voidputUnsignedByte(ByteBuffer bb, int value)
put Unsigned Byte 
bb.put((byte) (value & 0xff));
voidputUnsignedInt(ByteBuffer buffer, long value)
Write the given long value as a 4 byte unsigned integer. 
buffer.putInt((int) (value & 0xffffffffL));
voidputUnsignedInt(final ByteBuffer dst, final long value)
Put an unsigned int in the ByteBuffer at the current position. 
dst.putInt((int) (value & INT_FLAG_MASK_LONG));
ByteBufferputUnsignedShort(ByteBuffer bytes, int value)
put Unsigned Short 
if (bytes.remaining() < 2)
    throw new IOException("not enough space in buffer to write unsigned short");
if (value > 65535)
    throw new IOException("int value exceeds maximum unsigned short value of 65535!");
byte b1 = (byte) (0xff & (value >> 8));
byte b2 = (byte) (0xff & value);
bytes.put(b1);
bytes.put(b2);
...
ByteBufferputUUID(ByteBuffer bytes, UUID uuid)
put UUID 
if (bytes.remaining() < 16)
    throw new IOException("not enough space in buffer to write UUID value!");
long msb = uuid.getMostSignificantBits();
long lsb = uuid.getLeastSignificantBits();
bytes.putLong(msb);
bytes.putLong(lsb);
return bytes;
voidputVarint(ByteBuffer buffer, long number, int byteSize)
put Varint 
for (int i = 0; i < byteSize; i++) {
    int head = 128;
    if (i == byteSize - 1)
        head = 0;
    long b = ((number >> (7 * i)) & 127) ^ head;
    buffer.put((byte) (b & 255));
