Throws:

java.lang.IllegalArgumentException - if the specified byte order is not recognized.

getLong

public static final long getLong(byte[] buffer,
                                 int offset)

Build a Java long from an 8-byte signed binary representation.

Throws:

java.lang.IllegalArgumentException - if the specified byte order is not recognized.
