Method

intshift(int a, int b)
shift 
if ((0 < b) && (b < 32)) {
    return a << b;
} else if ((-32 < b) && (b < 0)) {
    return a >> (-b);
} else if (b == 0) {
    return a;
} else if (b >= 32) {
    return 0;
...
intshift(int component, int shift)
Bit shifts a color component, loosing the less significant bits 
return component >> shift;
longshift(int direction, long sq, int delta)
shift 
long result = sq;
for (int i = 0; i < delta; i++) {
    result = shift(direction, result);
return result;
intshift(int length)
shift 
int shift = 1;
int shifted = 2;
while (shifted <= length) {
    ++shift;
    shifted <<= 1;
return shift;
Stringshift(String string)
shift 
StringBuilder builder = new StringBuilder();
final String[] strings = string.split("\n");
for (String s : strings) {
    builder.append("    ").append(s).append("\n");
return builder.toString();
byteshiftBits(byte b)
shift Bits 
int upper = b << 4 & b1;
int lower = b >> 4 & b2;
return (byte) (upper | lower);
byteshiftByte(byte n, short shift)
shift Byte 
if (shift > 0) {
    return (byte) (n << shift);
} else {
    return (byte) (n >> -shift);
charshiftCharacter(char c, int offset)
shift Character 
return (char) (c + offset);
StringshiftDouble(Object o, double shift, String suffix)
shift Double 
Double d = parseDouble(o);
d = d + shift;
return (String.format("%.1f", d) + suffix);
intshiftHorizontally(int inkX, int inkXWidth, int textWidth)
Returns a shift of 'x' coordinate in pixels in order to fit the logical extent horizontally 
if ((inkX < 0) && (inkXWidth <= textWidth)) {
    return inkX;
if ((inkX + inkXWidth > textWidth) && (inkXWidth <= textWidth)) {
    return (inkX + inkXWidth - textWidth);
return 0;
