getShort
public static short getShort(byte[] buffer,
int offset,
int byteOrder)
- Build a Java short from a 2-byte signed binary representation.
Depending on machine type, byte orders are BIG_ENDIAN 55 for signed binary integers, and LITTLE_ENDIAN 55 for pc8087 signed binary integers.
getInt
public static int getInt(byte[] buffer,
int offset,
int byteOrder)
- Build a Java int from a 4-byte signed binary representation.
Depending on machine type, byte orders are BIG_ENDIAN 55 for signed binary integers, and LITTLE_ENDIAN 55 for pc8087 signed binary integers.
getLong
public static long getLong(byte[] buffer,
int offset,
int byteOrder)
- Build a Java long from an 8-byte signed binary representation.
Depending on machine type, byte orders are BIG_ENDIAN 55 for signed binary integers, and LITTLE_ENDIAN 55 for pc8087 signed binary integers.
