Method Detail

metrics

public Metrics.ReadAssociate metrics()

Returns:

access to metrics owned by the resource(s)

allChildren

public Resources.ReadAssociate allChildren()

Access to all children. Note that children that are existentially bound to this resource (i.e. in addition to Relationships.WellKnown.isParentOf there also exists the Relationships.WellKnown.contains relationship) cannot be disassociated using this interface.

Returns:

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

containedChildren

public Resources.ReadWrite containedChildren()

Returns:

access to children that are existentially bound to this/these resource(s)

parent

public Resources.Single parent()

Specified by:

parent in interface Resources.Single

Returns:

access to the parent resource (if any) that contains the resource on the current position in the path traversal. This resource will not exist for top-level resources living directly under an environment or feed.

parents

public Resources.Read parents()

Returns:

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

relationships

public Relationships.ReadWrite relationships()

Specified by:

relationships in interface Relatable<Relationships.ReadWrite>

Returns:

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

relationships

public Relationships.ReadWrite relationships(Relationships.Direction direction)

Specified by:

relationships in interface Relatable<Relationships.ReadWrite>

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.
