Method Detail

init

public void init(SerializationService serializationService,
        Data indexKey,
        Object key,
        Object value)

It may be useful to use this init method in some cases that same instance of this class can be used instead of creating a new one for every iteration when scanning large data sets, for example:

 Predicate predicate = ...
 QueryEntry entry = new QueryEntry()
 for(i == 0; i < HUGE_NUMBER; i++) {
       entry.init(...)
       boolean valid = predicate.apply(queryEntry);

       if(valid) {
          ....
       }
  }
