|
5 | * Represents a navigation property of an OData entity.
|
6 | *
|
7 | * OData is a relational data model, i.e. entities can be related to one another.
|
8 | * For example, BusinessPartner is in a 1:n relation with BusinessPartnerAddress and in a 1:1 relation with Customer.
|
9 | * Like normal properties, navigation properties can be used for selecting (expanding) and filtering.
|
10 | * For example, when constructing a query on the BusinessPartner entity, an instance of `Link<BusinessPartner, Customer>`
|
11 | * can be passed as argument to the select function, e.g. `BusinessPartner.TO_CUSTOMER`.
|
12 | *
|
13 | * NOTE: Due to historical development the Link and its extensions are used in the following way:
|
14 | * OData v2 entity: 1:N is a [[Link]], 1:0..1 is a [[OneToOneLink]]
|
15 | * OData v4 entity: 1:N is a [[OneToManyLink]], 1:0..1 is a [[OneToOneLink]]
|
16 | *
|
17 | * See also: [[Selectable]]
|
18 | * @typeparam EntityT - Type of the entity to be linked from
|
19 | * @typeparam LinkedEntityT - Type of the entity to be linked to
