Method Detail

metrics

public Metrics.Read metrics()

access to metrics owned by the resource(s)

allChildren

public Resources.ReadAssociate allChildren()

Returns:

access to all children of this/these resource(s) (superset of containedChildren(), also includes the resources bound merely by Relationships.WellKnown.isParentOf).

the parent resource(s) of the current resource(s)

relationships

public Relationships.Read relationships()

Specified by:

relationships in interface Relatable<Relationships.Read>

Returns:

the (r/w) access interface to all (outgoing) relationships of the entities on the current position in the inventory traversal.

relationships

public Relationships.Read relationships(Relationships.Direction direction)

Specified by:

relationships in interface Relatable<Relationships.Read>

Parameters:

direction - the direction of the relation (aka edge) This is needed because relationships are not bidirectional.

Returns:

the (r/w) access interface to all relationships of the entities on the current position in the inventory traversal.

entities

public Page<Resource> entities(Pager pager)

Specified by:

entities in interface ResolvableToMany<Resource>
