public final class FilterParamIndexIn
Index for filter parameter constants to match using the 'in' operator to match against a supplied set of values (i.e. multiple possible exact matches). The implementation is based on a regular HashMap.

get(Object filterConstant)
Get the event evaluation instance associated with the constant. |
ReadWriteLock |
getReadWriteLock()
Supplies the lock for protected access. |
void |
matchEvent(EventBean eventBean,
Collection<FilterHandle> matches)
Perform the matching of an event based on the event property values, adding any callbacks for matches found to the matches list. |
void |
put(Object filterConstant,
EventEvaluator evaluator)
Store the event evaluation instance for the given constant. |
