public abstract class ItemDefinitionImpl<I extends Item<?,?>>

implements ItemDefinition<I>, ItemDefinition.ItemDefinitionMutator, ItemDefinition.ItemDefinitionLikeBuilder, SerializableItemDefinition

Abstract item definition in the schema. This is supposed to be a superclass for all item definitions. Items are things that can appear in property containers, which generally means only a property and property container itself. Therefore this is in fact superclass for those two definitions. The definitions represent data structures of the schema. Therefore instances of Java objects from this class represent specific definitions from the schema, not specific properties or objects. E.g the definitions does not have any value. To transform definition to a real property or object use the explicit instantiate() methods provided in the definition classes. E.g. the instantiate() method will create instance of Property using appropriate PropertyDefinition. The convenience methods in Schema are using this abstract class to find appropriate definitions easily.

Field Details

itemName

@NotNull

protected boolean heterogeneousListItem

processing

protected ItemProcessing processing

Method Details

useSerializationProxy

protected static boolean useSerializationProxy(boolean localEnabled)

getItemName

@NotNull
public @NotNull ItemName getItemName()

Returns name of the defined entity. The name is a name of the entity instance if it is fixed by the schema. E.g. it may be a name of the property in the container that cannot be changed. The name corresponds to the XML element name in the XML representation of the schema. It does NOT correspond to a XSD type name. Name is optional. If name is not set the null value is returned. If name is not set the type is "abstract", does not correspond to the element.

Specified by:

getItemName in interface PrismItemBasicDefinition

Specified by:

getItemName in interface SerializableItemDefinition

Returns:

the name name of the entity or null.

getMinOccurs

public int getMinOccurs()

Description copied from interface: PrismItemBasicDefinition

setMaxOccurs

public void setMaxOccurs(int maxOccurs)

Specified by:

setMaxOccurs in interface PrismItemBasicDefinition.Mutable

isOperational

public boolean isOperational()

Description copied from interface: ItemDefinition

Marks operational item. Operational properties are auxiliary data (or meta-data) that are usually not modifiable by the end user. They are generated and maintained by the system. Operational items are also not usually displayed unless it is explicitly requested. The example of operational items are modification timestamps, create timestamps, user that made the last change, etc. They are also treated in a special way when comparing values. See ParameterizedEquivalenceStrategy.

Specified by:

isOperational in interface ItemDefinition<I extends Item<?,?>>

Specified by:

setAlwaysUseForEquals in interface ItemDefinition.ItemDefinitionMutator

isDynamic

public boolean isDynamic()

Description copied from interface: ItemDefinition

Returns true if definition was created during the runtime based on a dynamic information such as xsi:type attributes in XML. This means that the definition needs to be stored alongside the data to have a successful serialization "roundtrip". The definition is not part of any schema and therefore cannot be determined. It may even be different for every instance of the associated item (element name).

Specified by:

isDynamic in interface ItemDefinition<I extends Item<?,?>>

setDynamic

public void setDynamic(boolean dynamic)

Specified by:

setDynamic in interface ItemDefinition.ItemDefinitionMutator

getValueEnumerationRef

public PrismReferenceValue getValueEnumerationRef()

Description copied from interface: ItemDefinition

Reference to an object that directly or indirectly represents possible values for this item. We do not define here what exactly the object has to be. It can be a lookup table, script that dynamically produces the values or anything similar. The object must produce the values of the correct type for this item otherwise an error occurs.
