Method

shortunsignedToSigned16(char value)
Converts the specified unsigned 16 bit value to a signed 16 bit value. 
return (short) (value > Short.MAX_VALUE ? -(Character.MAX_VALUE - (value - 1)) : value);
shortunsignedToSigned8(char value)
Converts the specified unsigned 8 bit value to a signed 8 bit value. 
char workvalue = (char) (value & 0xff);
return (short) (workvalue > Byte.MAX_VALUE ? -(255 - (workvalue - 1)) : workvalue);
intunsignedUnion2by2(final short[] set1, final int length1, final short[] set2, final int length2, final short[] buffer)
Unite two sorted lists and write the result to the provided output array 
int pos = 0;
int k1 = 0, k2 = 0;
if (0 == length2) {
    System.arraycopy(set1, 0, buffer, 0, length1);
    return length1;
if (0 == length1) {
    System.arraycopy(set2, 0, buffer, 0, length2);
...
intunsignedUpcast(short s)
unsigned Upcast 
return s & 0xFFFF;
intunsignedValue(byte signedByte)
unsigned Value 
return signedByte & 0xff;
intunsignedVLQSize(int value)
unsigned VLQ Size 
if (value < 1 << 7) {
    return 1;
if (value < 1 << 14) {
    return 2;
if (value < 1 << 21) {
    return 3;
...
StringunsignedZerofill(Integer number, int offset)
Converts an integer to a unsigned zerofill representation specified by the given offset. 
String result = "";
while (result.length() < (offset - number.toString().length())) {
    result += "0";
return result + number.toString();
longunsignL(byte value)
Unsign the specified byte value and return it as long 
return value & 0xFFL;
