Method Detail

init

public void init(ComponentRegistry componentRegistry)

getCommandId

public byte getCommandId()

Description copied from interface: ReplicableCommand

Used by marshallers to convert this command into an id for streaming.

Returns:

the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.

writeTo

public void writeTo(ObjectOutput output)
             throws IOException

Description copied from interface: ReplicableCommand

Writes this instance to the ObjectOutput.

Parameters:

output - the stream.

Throws:

IOException - if an error occurred during the I/O.

readFrom

public void readFrom(ObjectInput input)
              throws IOException,
                     ClassNotFoundException

Description copied from interface: ReplicableCommand

Reads this instance from the stream written by ReplicableCommand.writeTo(ObjectOutput).

Parameters:

input - the stream to read.

Throws:

IOException - if an error occurred during the I/O.

ClassNotFoundException - if it tries to load an undefined class.

acceptVisitor

public Object acceptVisitor(InvocationContext ctx,
                            Visitor visitor)
                     throws Throwable

Description copied from interface: VisitableCommand

Accept a visitor, and return the result of accepting this visitor.

Parameters:

ctx - invocation context

visitor - visitor to accept

Returns:

arbitrary return value

Throws:

Throwable - in the event of problems

loadType

public VisitableCommand.LoadType loadType()

Returns:

Nodes on which the command needs to read the previous values of the keys it acts on.

performOnLostData

public Object performOnLostData()

Apply function on entry without any data

toString

public String toString()

Overrides:

toString in class AbstractDataCommand

getFunction

public Function<EntryView.ReadEntryView<K,V>,R> getFunction()

getKeyDataConversion

public DataConversion getKeyDataConversion()

getValueDataConversion

public DataConversion getValueDataConversion()

getParams
