Class UUID

java.lang.Object
  org.apache.jackrabbit.uuid.UUID

All Implemented Interfaces:

Serializable, Comparable, Constants

Deprecated. This class will be removed in Jackrabbit 2.0. Use java.util.UUID instead.

public class UUID
extends Object
implements Constants, Serializable, Comparable

UUID represents a Universally Unique IDentifier per IETF RFC 4122 ("A Universally Unique IDentifier (UUID) URN Namespace"), Section 4.

This is a lightweight implementation of an UUID, disregarding the different versions of UUIDs.

UUID

public UUID(DataInput input)
     throws IOException

Deprecated.

Constructs a UUID from a DataInput. Note if 16 bytes are not available this method will block.

Parameters:

input - the datainput with 16 bytes to read in from.

Throws:

IOException - exception if there is an IO problem also argument must contain 16 bytes.

UUID

public UUID(long mostSignificant,
            long leastSignificant)

Deprecated.

Constructs a UUID from two long values in most significant byte, and least significant bytes order.

Parameters:

mostSignificant - the most significant 8 bytes of the uuid to be constructed.

leastSignificant - the least significant 8 bytes of the uuid to be constructed.

UUID

public UUID(String uuidString)
     throws IllegalArgumentException

Deprecated.
