                              int ofs)

toBytesBigEndian

public static byte[] toBytesBigEndian(long val)

toLong

public static long toLong(byte[] bytes)

Converts a byte array to a long value.

Parameters:

bytes - array of bytes

offset - offset into array

length - length of data (must be #SIZEOF_LONG)

Returns:

the long value

Throws:

java.lang.IllegalArgumentException - if length is not #SIZEOF_LONG or if there's not enough room in the array at the offset indicated.

flipByteArray
