Class XJoinChain

java.lang.Object

org.apache.lens.api.metastore.XField

org.apache.lens.api.metastore.XJoinChain

All Implemented Interfaces:

org.jvnet.jaxb2_commons.lang.ToString

public class XJoinChain
extends XField
implements org.jvnet.jaxb2_commons.lang.ToString

Join chain represents the paths to reach a dimension. For example, to reach Country from SalesCube, there can be the following equivalent paths: SalesCube.deliveryStateid -> State.id, State.countryid -> Country.id SalesCube.deliveryCityid -> City.id, City.stateid -> State.id, State.countryid ->Country.id Both the above paths will be associated with same join chain i.e with same name, if they are equivalent and at runtime, LENS will choose the path to use. If the paths are not equivalent, they should be named differently. SalesCube.productionStateid -> State.id, State.countryid ->Country.id will be named differently.
