Method Details

init

public void init(ComponentRegistry componentRegistry)

Specified by:

init in interface VisitableCommand

Overrides:

init in class AbstractWriteManyCommand<K,V>

getBiFunction

public BiFunction<T,EntryView.ReadWriteEntryView<K,V>,R> getBiFunction()

getArguments

public Map<?,?> getArguments()

setArguments

public void setArguments(Map<?,?> arguments)

withArguments

public final ReadWriteManyEntriesCommand<K,V,T,R> withArguments(Map<?,?> entries)

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.

isForwarded

public boolean isForwarded()

Overrides:

isForwarded in class AbstractWriteManyCommand<K,V>

setForwarded

public void setForwarded(boolean forwarded)

Overrides:

setForwarded in class AbstractWriteManyCommand<K,V>

isReturnValueExpected

public boolean isReturnValueExpected()

Description copied from interface: ReplicableCommand

If true, a return value will be provided when performed remotely. Otherwise, a remote ResponseGenerator may choose to simply return null to save on marshalling costs.

Returns:

true or false

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

isSuccessful

public boolean isSuccessful()

Description copied from interface: WriteCommand

Some commands may want to provide information on whether the command was successful or not. This is different from a failure, which usually would result in an exception being thrown. An example is a putIfAbsent() not doing anything because the key in question was present. This would result in a isSuccessful() call returning false.

Specified by:

isSuccessful in interface ReplicableCommand

Specified by:

isSuccessful in interface WriteCommand

Overrides:

isSuccessful in class AbstractWriteManyCommand<K,V>

Returns:

true if the command completed successfully, false otherwise.

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.

Specified by:

isConditional in interface WriteCommand

Overrides:

isConditional in class AbstractWriteManyCommand<K,V>

Returns:

true if the command is conditional, false otherwise

getAffectedKeys

public Collection<?> getAffectedKeys()

Returns:

a collection of keys affected by this write command. Some commands - such as ClearCommand - may return an empty collection for this method.

loadType

public VisitableCommand.LoadType loadType()

Returns:

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

toString

public String toString()

Overrides:

toString in class Object

getKeysToLock

public Collection<?> getKeysToLock()

Description copied from interface: RemoteLockCommand

It returns a Collection with the keys to be lock.

It may return an empty collection if no keys needs to be locked independently of the return value of RemoteLockCommand.hasSkipLocking(). It may contains duplicated keys and null is not a valid return value.

Returns:

a Collection of keys to lock.

toMutation

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