Package com.orchestranetworks.addon.dmdv.data.filter Description

Provides the interfaces and class to define a filter that depends on the currently evaluated link. An administrator can include the custom filter in a link configuration. See the Developers Guide for more information.

Create custom filter class implements DisplayFilter:

1. Example of getting the current link's start and end node:

   NodeContext startNodeContext = context.getLink().getStartNodeContext();
   NodeContext endNodeContext = context.getLink().getEndNodeContext();
           

2. Example of getting the field's data from the start node:

   NodeContext startNodeContext = context.getLink().getStartNodeContext();
   Object id = startNodeContext.getNode().getRecord().get(Path.parse("./Id"));
           

3. Example of getting all sources/targets/children/parents of start node:

   //get parents
   List<NodeContext> parentNodecontexts = context.getLink().getStartNodeContext()
           .getContexts(LinkType.CONTAINMENT, RelationShipType.TARGET);
   
   //get children
   List<NodeContext> childrenNodecontexts = context.getLink().getStartNodeContext()
           .getContexts(LinkType.CONTAINMENT, RelationShipType.SOURCE);
   
   //get sources
   List<NodeContext> sourcesNodecontexts = context.getLink().getStartNodeContext()
           .getContexts(LinkType.LINE, RelationShipType.SOURCE);
   
   //get targets
   List<NodeContext> targetsNodecontexts = context.getLink().getStartNodeContext()
           .getContexts(LinkType.LINE, RelationShipType.TARGET);
