Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class UUID

toStringLong

public java.lang.String toStringLong()

Description copied from class: UUID

Returns a String object representing this UUID.

The UUID string representation is as described by this BNF:

 UUID                   = <time_low> "-" <time_mid> "-"
                          <time_high_and_version> "-"
                          <variant_and_sequence> "-"
                          <node>
 time_low               = 4*<hexOctet>
 time_mid               = 2*<hexOctet>
 time_high_and_version  = 2*<hexOctet>
 variant_and_sequence   = 2*<hexOctet>
 node                   = 6*<hexOctet>
 hexOctet               = <hexDigit><hexDigit>
 hexDigit               =
       "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
       | "a" | "b" | "c" | "d" | "e" | "f"
       | "A" | "B" | "C" | "D" | "E" | "F"
 

Overrides:

toStringLong in class UUID

Returns:

A string representation of this UUID
