PropertyEdge

open class PropertyEdge<T : Node> : Persistable

This class represents an edge between two Node objects in a Neo4J graph. It can be used to store additional information that relate to the relationship between the two nodes that belong to neither of the two nodes directly.

An example would be the name (in this case a) of an argument between a CallExpression (foo) and its argument (a Literal of 2) in languages that support keyword arguments, such as Python:

foo("bar", a = 2)

Constructors

fun <T : Node> PropertyEdge(start: Node, end: T)

Functions

fun addProperties(propertyMap: Map<Properties, Any?>?)

fun addProperty(property: Properties, value: Any?)

Adds a property to a PropertyEdge If the object is not a built-in type you must provide a serializer and deserializer in the PropertyEdgeConverter

containsProperties

fun containsProperties(props: Map<Properties, Any?>): Boolean

Checks if the properties of the edge contain the given properties with the specified values.
