public interface PrismContainer<C extends Containerable>
extends Item<PrismContainerValue<C>,PrismContainerDefinition<C>>, PrismContainerable<C>

Prism container groups items into logical blocks. The reason for grouping may be as simple as better understandability of data structure. But the group usually means different meaning, source or structure of the data. For example, the a container is frequently used to hold properties that are dynamic, not fixed by a static schema. Such grouping also naturally translates to XML and helps to "quarantine" such properties to avoid Unique Particle Attribute problems.

Container contains a set of (potentially multi-valued) properties, references, or inner containers. The order of properties is not significant, regardless of the fact that it may be fixed in the XML representation. In the XML representation, each element inside the container must be either property, reference, or a container.

A container is mutable.

Method Details

getDefinition

PrismContainerDefinition<C> getDefinition()

Description copied from interface: Item

Returns applicable definition.

May return null if no definition is applicable or the definition is not known.

Specified by:

getDefinition in interface Item<PrismContainerValue<C extends Containerable>,PrismContainerDefinition<C extends Containerable>>

Specified by:

getDefinition in interface Itemable

Specified by:

getDefinition in interface PrismContainerable<C extends Containerable>

Returns:

applicable definition

getCompileTimeClass

@Nullable
@Nullable Class<C> getCompileTimeClass()

Returns the static type of data represented by values of this container, if known and applicable. (There are containers that are purely dynamic, i.e. without any compile time class.)

Specified by:

getCompileTimeClass in interface PrismContainerable<C extends Containerable>

canRepresent

boolean canRepresent(@NotNull
 @NotNull Class<?> compileTimeClass)

Returns true if values of this container can be represented as specified compile-time class. For example, PrismContainer of AbstractRoleType has: - canRepresent(AbstractRoleType.class) = true - canRepresent(FocusType.class) = true - canRepresent(ObjectType.class) = true - canRepresent(TaskType.class) = false - canRepresent(RoleType.class) = false

canRepresent

boolean canRepresent(QName type)

Returns true if values of this container can be presented as specified type (from compile-time or runtime schema). In particular, returns true if type of this container or any of its supertypes match given type.

getRealValues

@NotNull
@NotNull Collection<C> getRealValues()

Description copied from interface: Item

Returns (potentially empty) collection of "real values".

Specified by:

getRealValues in interface Item<PrismContainerValue<C extends Containerable>,PrismContainerDefinition<C extends Containerable>>

Returns:

List of current values. The list itself is freely modifiable - it is independent on the list of values in this container. However, values themselves are directly linked to the PCVs.

getRealValue

@NotNull
C getRealValue()

Description copied from interface: Item

Returns the "real value" (content) of this item: - value contained in PrismPropertyValue - Referencable in PrismReferenceValue - Containerable in PrismContainerValue - Objectable in PrismObjectValue Note that the real value can contain operational items. It can also contain container IDs (although they are not considered to be part of the real value). It does not contain information about item element name nor other metadata like origin, definition, etc. (Although e.g. Containerable can be converted back into PrismContainerValue that can be used to retrieve this information.)

Specified by:

getRealValue in interface Item<PrismContainerValue<C extends Containerable>,PrismContainerDefinition<C extends Containerable>>

setRealValue

void setRealValue(C value)
           throws SchemaException

Throws:

SchemaException

Throws:

SchemaException

getValue

@NotNull
@NotNull PrismContainerValue<C> getValue()

Description copied from interface: Item

Returns the value, if there is only one. Throws exception if there are more values. If there is no value, this method either: - returns null (for properties) - throws an exception (for items that can hold multiple values) - creates an empty value (for containers and references). TODO think again whether getOrCreateValue would not be better

Specified by:

getValue in interface Item<PrismContainerValue<C extends Containerable>,PrismContainerDefinition<C extends Containerable>>

getValue

PrismContainerValue<C> getValue(Long id)

getValues

@NotNull
@NotNull List<PrismContainerValue<C>> getValues()
