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

Defines the many side of a many-to-many or many-to-one relationship between two Nodes

Parameters

property

type

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

direction

direction of the relation (direction associated with Neo4j relationship)
