Constructor Details

ReadWriteKeyCommand

public ReadWriteKeyCommand(ByteString cacheName,
 Object key,
 Function<EntryView.ReadWriteEntryView<K,V>, R> f,
 int segment,
 CommandInvocationId id,
 ValueMatcher valueMatcher,
 Params params,
 DataConversion keyDataConversion,
 DataConversion valueDataConversion)

Method Details

init

public void init(ComponentRegistry componentRegistry)

Specified by:

init in interface VisitableCommand

Overrides:

init in class AbstractWriteKeyCommand<K,V>

isConditional

public boolean isConditional()

Description copied from interface: WriteCommand

Certain commands only work based on a certain condition or state of the cache. For example, ConcurrentMap.putIfAbsent(Object, Object) only does anything if a condition is met, i.e., the entry in question is not already present. This method tests whether the command in question is conditional or not.

Returns:

true if the command is conditional, false otherwise

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.

toMutation

public Mutation<K,V,?> toMutation(Object key)

getFunction

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

supportedSince

public NodeVersion supportedSince()

Description copied from interface: ReplicableCommand

Returns a NodeVersion representing the Infinispan version in which this command was added. This value is used to ensure that when the cluster contains different Infinispan versions, only commands compatible with the oldest version are transmitted.

Abstract classes should not implement this method as the version should be specific to an individual implementation. Similarly, implementations which extend another ReplicableCommand should always override this method.

Returns:

a NodeVersion corresponding to the Infinispan version this command was added.

toString

public String toString()

Overrides:

toString in class AbstractWriteKeyCommand<K,V>
