-/**
- * This class represents a 128-bit UUID value.
- *
- * There are several types of UUID, and while this class can be used to store
- * them, only the Leach-Salz (variant 2) UUID specified in RFC-4122 will
- * give meaningful results from the method calls.
- * See: http://tools.ietf.org/html/4122 for the details
- *
- * The format of a Leach-Salz (variant 2) time-based (version 1) UUID
- * is as follows:
- * time_low - upper 32 bits of the most significant 64 bits,
- *            this is the least-significant part of the timestamp.
- *
- * time_mid - bits 16-31 of the most significant 64 bits,
- *            this is the middle portion of the timestamp.
- *
- * version  - bits 8-15 of the most significant 64 bits.
- *
- * time_hi  - bits 0-7 of the most significant 64 bits,
- *            the most significant portion of the timestamp.
- *
- * clock_and_reserved  - bits 48-63 of the least significant 64 bits.
- *                       a variable number of bits hold the variant
- *                       (see the spec)
- *
- * node identifier     - bits 0-47 of the least signficant 64 bits.
- *
- * These fields are valid only for version 1, in the remaining versions,
- * only the version and variant fields are set, all others are used for data.
- *
- * @since 1.5
