Method

byte[]fromInt(int input)
Returns a byte array containing 4 network byte-ordered bytes representing the given int . 
byte[] output = new byte[4];
output[0] = (byte) (input >> 24);
output[1] = (byte) (input >> 16);
output[2] = (byte) (input >> 8);
output[3] = (byte) input;
return output;
byte[]fromInt(int input)
Returns a byte array containing 4 big-endian ordered bytes representing the given integer. 
byte[] output = new byte[4];
writeInt(input, output, 0);
return output;
byte[]fromInt(int intValue)
Interpret an int as its binary form 
byte[] bytes = new byte[4];
bytes[0] = (byte) (intValue >> 24);
bytes[1] = (byte) ((intValue << 8) >> 24);
bytes[2] = (byte) ((intValue << 16) >> 24);
bytes[3] = (byte) ((intValue << 24) >> 24);
return bytes;
byte[]fromInt(int key)
from Int 
byte[] converted = new byte[4];
converted[0] = (byte) ((key >>> 24) & 0xFF);
converted[1] = (byte) ((key >>> 16) & 0xFF);
converted[2] = (byte) ((key >>> 8) & 0xFF);
converted[3] = (byte) (key & 0xFF);
return converted;
StringfromInt(int value)
from Int 
return String.valueOf(value);
byte[]fromInt(int value)
from Int 
return fromLong(value, 4);
byte[]fromInt(int value)
Converts an integer value to a byte array. 
byte[] result = { (byte) (0xFF & (value >>> 24)), (byte) (0xFF & (value >>> 16)),
        (byte) (0xFF & (value >>> 8)), (byte) (0xFF & value) };
return result;
voidfromInt(int value, byte[] arr, int offset)
from Int 
value ^= 1 << 31;
arr[offset] = (byte) (value >>> 24);
arr[offset + 1] = (byte) (value >>> 16);
arr[offset + 2] = (byte) (value >>> 8);
arr[offset + 3] = (byte) value;
boolean[]fromInt(int x, int size)
from Int 
boolean[] res = new boolean[size];
for (int i = 0; i < size; i++) {
    res[i] = (x & (1 << size - i - 1)) != 0;
return res;
EfromInteger(int idx, Class clazz)
from Integer 
if (idx == UNINITIALIZED)
    return null;
E[] vals = clazz.getEnumConstants();
return vals[idx];
