Constructor Detail

UniversalUniqueIdentifier

public UniversalUniqueIdentifier()

UniversalUniqueIdentifier default constructor returns a new instance that has been initialized to a unique value.

UniversalUniqueIdentifier

public UniversalUniqueIdentifier(byte[] byteValue)

Constructor that accepts the bytes to use for the instance. The format of the byte array is compatible with the toBytes() method.

The constructor returns the undefined uuid if the byte array is invalid.

See Also:

toBytes(), BYTES_SIZE

Method Detail

clone

public java.lang.Object clone()

Simply increases the visibility of Object's clone. Otherwise, no new behaviour.

Overrides:

clone in class java.lang.Object

compareTime

public static int compareTime(byte[] fBits1,
                              byte[] fBits2)

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toBytes

public byte[] toBytes()

This representation is compatible with the (byte[]) constructor.

See Also:

UniversalUniqueIdentifier(byte[])

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toStringAsBytes

public java.lang.String toStringAsBytes()
