Constructor Detail

UnlockEntryProcessor

public UnlockEntryProcessor()

UnlockEntryProcessor

public UnlockEntryProcessor(ExpiryMarker lock,
                    String nextMarkerId,
                    long timestamp)

Method Detail

process

public Void process(Map.Entry<Object,Expirable> 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.

Parameters:

entry - entry to be processed

Returns:

result of the process

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

Writes object fields to output stream

Parameters:

out - output

Throws:

IOException

readData

public void readData(ObjectDataInput in)
              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Parameters:

in - input

Throws:

IOException

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. Id should be unique per DataSerializableFactory.

Returns:

type id
