Method Summary

void	addElement(NakedObject owningNakedObject, NakedObject objectToAdd) Add the specified element to this collection field in the specified object.
void	clearCollection(NakedObject inObject) Remove all elements from this collection field in the specified object.
ValidityContext<?>	createValidateAddInteractionContext(AuthenticationSession session, InteractionInvocationMethod invocationMethod, NakedObject owningNakedObject, NakedObject proposedObjectToAdd) Creates an InteractionContext that represents validation of a candidate object to be added to the collection.
ValidityContext<?>	createValidateRemoveInteractionContext(AuthenticationSession session, InteractionInvocationMethod invocationMethod, NakedObject owningNakedObject, NakedObject proposedObjectToRemove) Creates an InteractionContext that represents validation of a candidate object to be removed from the collection.
Consent	isValidToAdd(NakedObject owningNakedObject, NakedObject proposedObjectToAdd) Determines if the specified element can be added to the collection field, represented as a Consent.
Consent	isValidToRemove(NakedObject owningNakedObject, NakedObject proposedObjectToRemove) Determines if the specified element can be removed from the collection field, represented as a Consent.
void	removeElement(NakedObject owningNakedObject, NakedObject oObjectToRemove) Remove the specified element from this collection field in the specified object.

Method Detail

createValidateAddInteractionContext

ValidityContext<?> createValidateAddInteractionContext(AuthenticationSession session,
                                                       InteractionInvocationMethod invocationMethod,
                                                       NakedObject owningNakedObject,
                                                       NakedObject proposedObjectToAdd)

Creates an InteractionContext that represents validation of a candidate object to be added to the collection.

Typically it is easier to just call isValidToAdd(NakedObject, NakedObject) or #isValidToAddResult(NakedObject, NakedObject); this is provided as API for symmetry with interactions (such as AccessContext accesses) have no corresponding vetoing methods.

isValidToAdd

Consent isValidToAdd(NakedObject owningNakedObject,
                     NakedObject proposedObjectToAdd)

Determines if the specified element can be added to the collection field, represented as a Consent.

If allowed the add method can be called with the same parameters, .

See Also:

#isValidToAddResult(NakedObject, NakedObject)

addElement

void addElement(NakedObject owningNakedObject,
                NakedObject objectToAdd)

Add the specified element to this collection field in the specified object.

createValidateRemoveInteractionContext

ValidityContext<?> createValidateRemoveInteractionContext(AuthenticationSession session,
                                                          InteractionInvocationMethod invocationMethod,
                                                          NakedObject owningNakedObject,
                                                          NakedObject proposedObjectToRemove)

Creates an InteractionContext that represents validation of a candidate object to be removed from the collection.

Typically it is easier to just call isValidToAdd(NakedObject, NakedObject) or #isValidToAddResult(NakedObject, NakedObject); this is provided as API for symmetry with interactions (such as AccessContext accesses) have no corresponding vetoing methods.

isValidToRemove

Consent isValidToRemove(NakedObject owningNakedObject,
                        NakedObject proposedObjectToRemove)

Determines if the specified element can be removed from the collection field, represented as a Consent.

If allowed the remove method can be called with the same parameters, .

See Also:

removeElement(NakedObject, NakedObject), #isValidToAddResult(NakedObject, NakedObject)

removeElement

void removeElement(NakedObject owningNakedObject,
                   NakedObject oObjectToRemove)

Remove the specified element from this collection field in the specified object.

clearCollection

void clearCollection(NakedObject inObject)

Remove all elements from this collection field in the specified object.
