abstract class RelationshipDefinition(val property: KProperty1<*, *>, val nodeKClass: KClass<out Node>, val type: String, val direction: Direction, val parentKClass: KClass<out Node>, val allowedAuthorizations: Set<String>)

Defines a relationship between two Nodes There may or may not be an inverse relation on the foreign node

Parameters

property

the property on the class which defines the relationship

nodeKClass

the class associated with the item nodes

type

the type of the relation (label associated with Neo4j relationship)

direction

direction of the relation (direction associated with Neo4j relationship)

parentKClass

the class associated with the NodeDefinition this is used as part of, must be a subclass of the property defining class

allowedAuthorizations

the names of authorizations which allow via this relation. These names result in properties with value true on the relation
