AtlasRelationshipDef is a TypeDef that defines a relationship. As with other typeDefs the AtlasRelationshipDef has a name. Once created the RelationshipDef has a guid. The name and the guid are the 2 ways that the RelationshipDef is identified. RelationshipDefs have 2 ends, each of which specify cardinality, an EntityDef type name and name and optionally whether the end is a container. RelationshipDefs can have AttributeDefs - though only primitive types are allowed. RelationshipDefs have a relationshipCategory specifying the UML type of relationship required The way EntityDefs and RelationshipDefs are intended to be used is that EntityDefs will define AttributeDefs these AttributeDefs will not specify an EntityDef type name as their types. RelationshipDefs introduce new attributes to the entity instances. For example EntityDef A might have attributes attr1,attr2,attr3

EntityDef B might have attributes attr4,attr5,attr6 RelationshipDef AtoB might define 2 ends

end1: type A, name attr7 end2: type B, name attr8

When an instance of EntityDef A is created, it will have attributes attr1,attr2,attr3,attr7 When an instance of EntityDef B is created, it will have attributes attr4,attr5,attr6,attr8

In this way relationshipDefs can be authored separately from entityDefs and can inject relationship attributes into the entity instances

Constructors

AtlasRelationshipDef()

Initializes a new instance of AtlasRelationshipDef.

Properties

AttributeDefs	An array of attribute definitions.
Category	The enum of type category.
CreatedBy	The user who created the record.
CreateTime	The created time of the record.
DateFormatter	The date format.
Description	The description of the type definition.
EndDef1	The relationshipEndDef represents an end of the relationship. The end of the relationship is defined by a type, an attribute name, cardinality and whether it is the container end of the relationship.
EndDef2	The relationshipEndDef represents an end of the relationship. The end of the relationship is defined by a type, an attribute name, cardinality and whether it is the container end of the relationship.
Guid	The GUID of the type definition.
LastModifiedTS	ETag for concurrency control.
Name	The name of the type definition.
Options	The options for the type definition.
RelationshipCategory	The Relationship category determines the style of relationship around containment and lifecycle. UML terminology is used for the values. ASSOCIATION is a relationship with no containment. COMPOSITION and AGGREGATION are containment relationships. The difference being in the lifecycles of the container and its children. In the COMPOSITION case, the children cannot exist without the container. For AGGREGATION, the life cycles of the container and children are totally independent.
RelationshipLabel	The label of the relationship.
ServiceType	The service type.
TypeVersion	The version of the type.
UpdatedBy	The user who updated the record.
UpdateTime	The update time of the record.
Version	The version of the record.

Explicit Interface Implementations

IJsonModel<AtlasRelationshipDef>.Create(Utf8JsonReader, ModelReaderWriterOptions)	Reads one JSON value (including objects or arrays) from the provided reader and converts it to a model.
IJsonModel<AtlasRelationshipDef>.Write(Utf8JsonWriter, ModelReaderWriterOptions)	Writes the model to the provided Utf8JsonWriter.
IPersistableModel<AtlasRelationshipDef>.Create(BinaryData, ModelReaderWriterOptions)	Converts the provided BinaryData into a model.
IPersistableModel<AtlasRelationshipDef>.GetFormatFromOptions(ModelReaderWriterOptions)	Gets the data interchange format (JSON, Xml, etc) that the model uses when communicating with the service.
IPersistableModel<AtlasRelationshipDef>.Write(ModelReaderWriterOptions)	Writes the model into a BinaryData.
