Method

intgetUShort(ByteBuffer buffer)
get U Short

intgetUShort(java.nio.ByteBuffer buffer)
get U Short 
return 0xFFFF & buffer.getShort();
intreadInt(ByteBuffer buf)
read Int 
if (buf.remaining() < 4) {
    throw new IOException("Not enough bytes in buffer to read integer");

...
intreadInt(ByteBuffer buf, int length)
read Int 
if ((buf.position() + length) <= buf.limit() && length <= 4) {
    int r = 0;
    for (int i = 0; i < length; i++) {
        r |= ((buf.get() & 0xff) << (i << 3));
    return r;
return 0;
...
intreadInt(ByteBuffer buf, int pos)
Reads a specific integer byte value (4 bytes) from the input byte buffer at the given offset. 
return (((buf.get(pos) & 0xff) << 24) | ((buf.get(pos + 1) & 0xff) << 16) | ((buf.get(pos + 2) & 0xff) << 8)
        | (buf.get(pos + 3) & 0xff));
intreadInt(ByteBuffer buffer)
read Int 
buffer.order(ByteOrder.LITTLE_ENDIAN);
int value = buffer.getInt();
buffer.order(ByteOrder.BIG_ENDIAN);
return value;
intreadInt(ByteBuffer buffer)
read Int 
int i = buffer.get() & 0xff;
i |= (buffer.get() & 0xff) << 8;
i |= (buffer.get() & 0xff) << 16;
i |= (buffer.get() & 0xff) << 24;
return i;
IntegerreadInt(ReadableByteChannel channel, ByteBuffer buffer)
read Int 
return readAndFlip(channel, buffer, 4) ? buffer.getInt() : null;
intreadInt16(ByteBuffer bb)
read Int 
return bb.getShort();
intreadInt32(ByteBuffer bb)
Read an 32-bit signed integer from the byte buffer. 
return bb.getInt();
