Constructor Detail

GetAttributeNamesEntryProcessor

public GetAttributeNamesEntryProcessor()

Method Detail

getJvmId

public String getJvmId()

setJvmId

public void setJvmId(String jvmId)

Description copied from interface: JvmIdAware

Sets jvm id.

Specified by:

setJvmId in interface JvmIdAware

Parameters:

jvmId - the jvm id

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory id for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory id

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

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

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type id

process

public Object process(Map.Entry<String,SessionState> 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<String,SessionState>

Parameters:

entry - entry to be processed

Returns:

result of the process

getBackupProcessor

public EntryBackupProcessor<String,SessionState> getBackupProcessor()

Description copied from interface: EntryProcessor

Get the entry processor to be applied to backup entries.

Specified by:

getBackupProcessor in interface EntryProcessor<String,SessionState>

Returns:

the back up processor

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

Specified by:

writeData in interface DataSerializable

Parameters:

out - output

Throws:

IOException

readData

public void readData(ObjectDataInput in)
              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Parameters:

in - input

Throws:

IOException
