  +--oracle.ldap.util.Guid

All Implemented Interfaces:

java.lang.Cloneable

public final class Guid

extends java.lang.Object

implements java.lang.Cloneable

This class represents GUIDs (Globally Unique Identifiers), or object IDs. This is an immutable class.

Field Summary

static int	GUID_BYTE_SIZE number of bytes required for GUID
static int	GUID_STRING_SIZE number of bytes required for the string representation of GUID

Guid(byte[] byte_array)
Construct a Guid from a byte array

Constructor Summary

Guid()
Default constructor.

Guid(java.lang.String guid)
Construct a Guid from a string

Method Summary

java.lang.Object	clone() Clones a Guid object
boolean	equals(java.lang.Object o) Compare the Guid in a string format
byte[]	getBytes() return the 'byte' form of the Guid
int	hashCode() return the hashcode of this object for hashing purposes
static void	main(java.lang.String[] argv) main function used for testing
static Guid	newInstance() generates a new Guid
java.lang.String	toString() Retrieves the Guid in a string format

number of bytes required for the string representation of GUID

Constructor Detail

Guid

public Guid()

Default constructor.

Guid

public Guid(java.lang.String guid)

Construct a Guid from a string

Parameters:

guid - a string representation of a Globally Unique Identifier

Guid

public Guid(byte[] byte_array)

Construct a Guid from a byte array

Parameters:

byte_array - an array of bytes representing a GUID. This constructor will validate the length of the byte array before proceeding.

Method Detail

newInstance

public static Guid newInstance()

generates a new Guid

Returns:

a new instance of the Guid class

getBytes

public byte[] getBytes()

return the 'byte' form of the Guid

Returns:

a byte array containing the Guid bytes

toString

public final java.lang.String toString()

Retrieves the Guid in a string format

Overrides:

toString in class java.lang.Object

Returns:

the Guid in a string format

equals

public boolean equals(java.lang.Object o)

Compare the Guid in a string format

Overrides:

equals in class java.lang.Object

Returns:

true if they are equal, false otherwise

hashCode

public int hashCode()

return the hashcode of this object for hashing purposes

Overrides:

hashCode in class java.lang.Object

Returns:

the integer hashcode of the Guid

clone

public java.lang.Object clone()

Clones a Guid object

Returns:

a clone of an existing Guid object

main

public static void main(java.lang.String[] argv)

main function used for testing
