Class NavigateCollectors.Endpoints

java.lang.Object
  wt.epm.structure.NavigateCollectors.AbstractCollector
      wt.epm.structure.NavigateCollectors.Endpoints

All Implemented Interfaces:

NavigateResultProcessor, ResultProcessor

Enclosing class:

NavigateCollectors

public static class NavigateCollectors.Endpoints

extends NavigateCollectors.AbstractCollector

This NavigateResultProcessor collects the endpoints of the links and adds them to a Collection or WTKeyedMap. The endpoints are two-element arrays where the first element is the query key for the object that we navigated from and the second element is the query key for the object that we navigated to (i.e. the other-side object).

Constructor Summary

NavigateCollectors.Endpoints(Collection collection)
With this constructor, the class will add the endpoints of the links to the given Collection.

NavigateCollectors.Endpoints(WTKeyedMap map, boolean reverse)
With this constructor, the class will add the endpoints of the links to the given WTKeyedMap.

Method Summary

void	addElement(Object object) Add the specified object to the result processor, and increase the size by one Supported API: false
void	selectWhatToReturn(Relationship relationship, QuerySpec querySpec) Specifies what objects or attributes to return when navigating a Binary link from one set of objects to another.

Constructor Detail

NavigateCollectors.Endpoints

public NavigateCollectors.Endpoints(Collection collection)

With this constructor, the class will add the endpoints of the links to the given Collection. The endpoints are two-element arrays where the first element is the query key for the object that we navigated from and the second element is the query key for the object that we navigated to (i.e. the other-side object).

NavigateCollectors.Endpoints

public NavigateCollectors.Endpoints(WTKeyedMap map,
                                    boolean reverse)

With this constructor, the class will add the endpoints of the links to the given WTKeyedMap.

If the reverse flag is false, the values will be WTSets that hold the query keys for the other-side objects and the keys will be the query keys for the objects that we navigated from.

If the reverse flag is true, the keys will be the query keys for the other-side objects and the values will be WTSets that hold the query keys for the objects that we navigated from.
