Constructor Summary

OneToOneActionParameterImpl(int index, NakedObjectActionImpl actionImpl, NakedObjectActionParamPeer peer)

Method Summary

NakedObject	get(NakedObject owner) Gets the proposed value of the Instance (downcast as a MutableProposed, wrapping the proposed value into a NakedObject.
Instance	getInstance(NakedObject nakedObject) Return an Instance of this Specification with respect to the provided NakedObject.
boolean	isObject() Subclasses should override either NakedObjectActionParameterAbstract.isObject() or NakedObjectActionParameterAbstract.isCollection().
java.lang.String	isValid(NakedObject nakedObject, java.lang.Object proposedValue) TODO: need to be able to validate parameters individually, eg if have RegEx annotation; should delegate to the Check framework instead.
void	set(NakedObject owner, NakedObject newValue) Sets the proposed value of the Instance (downcast as a MutableProposed, unwrapped the proposed value from a NakedObject.

Constructor Detail

OneToOneActionParameterImpl

public OneToOneActionParameterImpl(int index,
                                   NakedObjectActionImpl actionImpl,
                                   NakedObjectActionParamPeer peer)

Method Detail

isObject

public boolean isObject()

Description copied from class: NakedObjectActionParameterAbstract

Subclasses should override either NakedObjectActionParameterAbstract.isObject() or NakedObjectActionParameterAbstract.isCollection().

Specified by:

isObject in interface NakedObjectActionParameter

Overrides:

isObject in class NakedObjectActionParameterAbstract

isValid

public java.lang.String isValid(NakedObject nakedObject,
                                java.lang.Object proposedValue)

TODO: need to be able to validate parameters individually, eg if have RegEx annotation; should delegate to the Check framework instead.

Specified by:

isValid in interface NakedObjectActionParameter

Returns:

getInstance

public Instance getInstance(NakedObject nakedObject)

Description copied from interface: Specification

Return an Instance of this Specification with respect to the provided NakedObject.

For example, if the Specification is a OneToOneAssociation, then is an Instance implementation representing the { NakedObject/ OneToOneAssociation } tuple.

Implementations are expected to use a double-dispatch back to the provided NakedObject (passing themselves as a parameter), using NakedObjectMM.getInstance(Specification).

Note: this method may throw an UnsupportedOperationException; see NakedObjectMM.getInstance(Specification) for details.

Specified by:

getInstance in interface Specification

get

public NakedObject get(NakedObject owner)

Gets the proposed value of the Instance (downcast as a MutableProposed, wrapping the proposed value into a NakedObject.

Specified by:

get in interface CurrentHolder

set

public void set(NakedObject owner,
                NakedObject newValue)

Sets the proposed value of the Instance (downcast as a MutableProposed, unwrapped the proposed value from a NakedObject.
