BasicNodeQuery
public class BasicNodeQuery extends BasicQuery implements NodeQuery(Code)
'Basic' implementation of bridge NodeQuery. Wraps a Query with all and only fields of one Step. If there is only one step, this can wrap NodeSearchQuery of core. Often, queries with more steps are sensible nodequeries, because sorting (e.g. posrel.pos) or filtering can be done on those steps (e.g. publishtimes). Nodes of this type can be used as an argument to function which do return 'real' nodes (so not clusternodes).

Constructor Detail
BasicNodeQuery
BasicNodeQuery(Cloud c)(Code)



BasicNodeQuery
BasicNodeQuery(BasicNodeManager nodeManager)(Code)
node query.



BasicNodeQuery
BasicNodeQuery(BasicNodeManager nodeManager, NodeSearchQuery q)(Code)
