determineTargetEntityType

public static org.apache.olingo.commons.api.edm.EdmEntityType determineTargetEntityType(List<org.apache.olingo.server.api.uri.UriResource> resources)

Finds an entity type from a navigation property

determineStartNavigationPath

public static org.apache.olingo.server.api.uri.UriResourceProperty determineStartNavigationPath(List<org.apache.olingo.server.api.uri.UriResource> resources)

Used for Serializer

determineStartNavigationIndex

public static int determineStartNavigationIndex(List<org.apache.olingo.server.api.uri.UriResource> resources)

Example1 : /Organizations -> -1
Example2 : /Organizations('3')/AdministrativeInformation -> 1
Example3 : /Organizations('3')/Roles -> -1
Example4 : /Organizations('3')/Roles/RoleCategory -> 2
Example4 : /Organizations('3')/AdministrativeInformation/Created/User/LastName -> 4
