Constructor Detail

Guid

public Guid()

Creates a Guid object

Guid

public Guid(java.lang.String guidHexString)

Construct a Guid from its string representation

Parameters:

guidHexString - a non null Hex string representing a Globally Unique Identifier. The string can be either in the expanded or compact form

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 Object. This Guid is unique across time and space

Returns:

a new instance of the Guid class

getBytes

public byte[] getBytes()

return the byte array 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 Object for equality with this guid

Overrides:

equals in class java.lang.Object

Parameters:

o - object to be compared for equality

Returns:

true if they are equal, false otherwise

equals

public boolean equals(Guid guid)

Compare the Guid for equality with this guid

Parameters:

guid - object to be compared for equaity

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

Overrides:

clone in class java.lang.Object

Returns:

a clone of an existing Guid object

main
