| ClusterBuilder | | public class ClusterBuilder extends VirtualBuilder (Code) | | The builder for
ClusterNode clusternodes .
Provides these methods to retrieve clusternodes:
-
ClusterBuilder.getClusterNodes(SearchQuery) to retrieve clusternodes using a
SearchQuery (recommended).
-
ClusterBuilder.getMultiLevelSearchQuery(List,List,String,List,String,List,List,int) as a convenience method to create a
SearchQuery
-
ClusterBuilder.searchMultiLevelVector(List,List,String,List,String,List,List,int) to retrieve clusternodes using a constraint string.
Individual nodes in a 'cluster' node can be retrieved by calling the node's
MMObjectNode.getNodeValue(String) getNodeValue() method, using
the builder name (or step alias) as argument.
