public interface QueryNodeProcessor
A
QueryNodeProcessor
is an interface for classes that process a QueryNode
tree.
The implementor of this class should perform some operation on a query node tree and return the same or another query node tree.
It also may carry a QueryConfigHandler
object that contains configuration about the
query represented by the query tree or the collection/index where it's intended to be executed.
In case there is any QueryConfigHandler
associated to the query tree to be processed,
it should be set using setQueryConfigHandler(QueryConfigHandler)
before process(QueryNode)
is invoked.
