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
for signed binary integers, andLITTLE_ENDIAN
for pc8087 signed binary integers.- Throws:
java.lang.IllegalArgumentException
- if the specified byte order is not recognized.
-
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
for signed binary integers, andLITTLE_ENDIAN
for pc8087 signed binary integers.- Throws:
java.lang.IllegalArgumentException
- if the specified byte order is not recognized.
-
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
