This class holds a list of indizes storing filter constants in net.esper.filter.FilterParamIndex nodes
and a set of net.esper.filter.FilterCallback.
An instance of this class represents a leaf-node (no indizes stored, just filter callbacks)
but can also be non-leaf (some indizes exist) in a filter evaluation tree.
Events are evaluated by asking each of the indizes to evaluate the event and by
adding any filter callbacks in this node to the "matches" list of callbacks.
The following tables list the members exposed by the FilterCallbackSetNode type.
