allMetrics

public Metrics.Read allMetrics()

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.

entities

public Page<Environment> entities(Pager pager)

Specified by:

entities in interface ResolvableToMany<Environment>
