Method Detail

get

public abstract ObjectAdapter get(ObjectAdapter fromObject)

Description copied from interface: CurrentHolder

Returns the referenced ObjectAdapter for the owning ObjectAdapter.

For example, if this is an OneToOneAssociation, then returns the referenced object.

Specified by:

get in interface CurrentHolder

getSpecification

public ObjectSpecification getSpecification()

Return the specification of the object (or objects) that this field holds. For a value are one-to-one reference this will be type that the accessor returns. For a collection it will be the type of element, not the type of collection.

Specified by:

getSpecification in interface ObjectFeature

isNotPersisted

public boolean isNotPersisted()

Description copied from interface: ObjectAssociation

Returns true if calculated from other data in the object, that is, should not be persisted.

Specified by:

isNotPersisted in interface ObjectAssociation

hasChoices

public boolean hasChoices()

Description copied from interface: ObjectAssociation

Whether there are any choices provided (eg choicesXxx supporting method) for the association.

Specified by:

hasChoices in interface ObjectAssociation

isMandatory

public boolean isMandatory()

Description copied from interface: ObjectAssociation

Determines if this field must be complete before the object is in a valid state

Specified by:

isMandatory in interface ObjectAssociation

isEmpty

public abstract boolean isEmpty(ObjectAdapter adapter)

Description copied from interface: ObjectAssociation

Returns true if this field on the specified object is deemed to be empty, or has no content.

Specified by:

isEmpty in interface ObjectAssociation

isOneToOneAssociation

public boolean isOneToOneAssociation()

Description copied from interface: ObjectMember

Whether this member represents a OneToOneAssociation.

If so, can be safely downcast to OneToOneAssociation.

Specified by:

isOneToOneAssociation in interface ObjectMember

Overrides:

isOneToOneAssociation in class ObjectMemberAbstract

getBusinessKeyName

public String getBusinessKeyName()

Description copied from interface: ObjectAssociation

Get the name for the business key, if one has been specified.

Specified by:

getBusinessKeyName in interface ObjectAssociation
