Target-independent tools for several byte conversions.
ByteConvert can:
- Convert signed and unsigned integers to and from an array of 8-bit bytes.
- Change the endianess of signed and unsigned integers.
- Convert a single byte to and from an array of 1s and 0s.
- Read and write Ints and UInts from an array of bytes.
- Read and set specific bits of a number.
All features, except single-byte, work with 16-, 32-, and 64-bit lengths.
64-bit operations aren't supported on 32-bit systems.
Install with: haxelib install byteConvert
Add -lib byteConvert to compilation flags.
Import it with: import byteConvert.ByteConvert
Optional static extension with using byteConvert.ByteConvert
import byteConvert.ByteConvert;
class Example
{
public static function main()
{
trace( ByteConvert.toInt16([0x10, 0x20]) ); // prints 4128, (0x1020)
trace( ByteConvert.toUInt32([0x10, 0x20, 0x30, 0x40]) ); // prints 270544960, (0x10203040)
trace( ByteConvert.readUInt16([0x10, 0x20, 0x30, 0x40], 1) ); // prints 8240, (0x2030)
trace( ByteConvert.fromInt16(43775) ); // prints [170, 255], ([0xAA, 0xFF])
trace( ByteConvert.flipEndian32(0x11DD77FF) ); //prints 4286045457, (0xFF77DD11)
var ar:Array<Int> = [0x10, 0x20, 0x30, 0x40];
trace(readInt16(ar, 2)); // prints 12352 (0x3040)
ByteConvert.writeInt16(ar, 1, 0xaaff);
trace(ar); //prints 279641920, (10aaff40)
trace(byteConvert.bit(0x04, 2)); // prints 1
trace(byteConvert.bits(0x04, 1, 3)); // prints 2
trace(byteConvert.bit(0x04, 0, 1)); // prints 5
trace(byteConvert.bits(0x04, 1, 3, 5)); // prints 14
}
}
As static extension
import byteConvert.ByteConvert;
using byteConvert.ByteConvert;
class Example
{
public static function main()
{
trace( [0x10, 0x20].toInt16() ); // prints 4128, (0x1020)
trace( [0x10, 0x20, 0x30, 0x40].toUInt32() ); // prints 270544960, (0x10203040)
trace( [0x10, 0x20, 0x30, 0x40].readUInt16(1) ); // prints 8240, (0x2030)
trace( 43775.fromInt16() ); // prints [170, 255], ([0xAA, 0xFF])
trace( 0x11DD77FF.flipEndian32() ); //prints 4286045457, (0xFF77DD11)
var ar:Array<Int> = [0x10, 0x20, 0x30, 0x40];
trace(ar.readInt16(2)); // prints 12352 (0x3040)
ar.writeInt16(1, 0xaaff);
trace(ar); //prints 279641920, (10aaff40)
trace(0x04.bit(2)); // prints 1
trace(0x04.bits(1, 3)); // prints 2
trace(0x04.bit(0, 1)); // prints 5
trace(0x04.bits(1, 3, 5)); // prints 14
