Method Detail

process

public Object process(Map.Entry entry)

Description copied from interface: EntryProcessor

Process the entry without worrying about concurrency.

Note that to modify an entry by using EntryProcessor you should explicitly call Map.Entry.setValue(V) method of Map.Entry such as:

 
 Override
        public Object process(Map.Entry entry) {
          Value value = entry.getValue();
          // process and modify value
          // ...
          entry.setValue(value);
          return result;
        }
 
 

otherwise EntryProcessor does not guarantee to modify the entry.

Specified by:

process in interface EntryProcessor

Parameters:

entry - entry to be processed

Returns:

result of the process

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory id for this class.

Specified by:
