Constructor Summary

FreezableDelegatingMutableSet(java.io.Serializable identifier, java.lang.String role, Mother mom)

FreezableDelegatingMutableSet(java.io.Serializable identifier, java.lang.String role, Mother mom, CollectionOfFreezables c)

FreezableDelegatingMutableSet(java.io.Serializable identifier, java.lang.String role, Mother mom, FreezableDelegatingMutableSet c)
Creates a new Set that is a copy of c

Method Summary

protected MutableSetOfFreezables	createDelegate() Only called by DelegatingMutableSet's constructor.
Freezable	createEvilClone(Mother mom, java.lang.String role) Returns a new instance of a Freezable with the same internal state as this Freezable, but with the new id.
java.io.Serializable	getIdentifier() Get the identifier for this instance.
java.lang.String	getRole() Get the role for this instance.
boolean	sameAs(Freezable object) Returns true if this Freezable represents the samee information as object, and their internal state matches.
boolean	sameIdentifierAs(Freezable object) Returns true if this Freezable represents the same information as the Freezable object, ie if they have the same identifier.

Creates a new Set that is a copy of c

Method Detail

createDelegate

protected MutableSetOfFreezables createDelegate()

Only called by DelegatingMutableSet's constructor. Override this method to change the delegate MutableSet.

Specified by:

createDelegate in class DelegatingMutableSet

getIdentifier

public java.io.Serializable getIdentifier()

Description copied from interface: Freezable

Get the identifier for this instance. I've always used a Long, but the ejb spec says it can be anything. Try to use something immutable. Note that you will only have this Object plus metadetails of the class to use for identifier information. All you should need is the identifier.

Specified by:

getIdentifier in interface Freezable

getRole

public java.lang.String getRole()

Description copied from interface: Freezable

Get the role for this instance.

Specified by:

getRole in interface Freezable

sameIdentifierAs

public boolean sameIdentifierAs(Freezable object)

Description copied from interface: Freezable

Returns true if this Freezable represents the same information as the Freezable object, ie if they have the same identifier.

Specified by:

sameIdentifierAs in interface Freezable

sameAs

public boolean sameAs(Freezable object)

Description copied from interface: Freezable

Returns true if this Freezable represents the samee information as object, and their internal state matches.

Specified by:

sameAs in interface Freezable

createEvilClone

public Freezable createEvilClone(Mother mom,
                                 java.lang.String role)

Description copied from interface: Freezable

Returns a new instance of a Freezable with the same internal state as this Freezable, but with the new id. This method should only be called by Mother.

Specified by:

createEvilClone in interface Freezable
