Method Detail

getCommandId

public byte getCommandId()

Description copied from interface: ReplicableCommand

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

Specified by:

getCommandId in interface ReplicableCommand

Overrides:

getCommandId in class InvalidateCommand

Returns:

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

setKeys

public void setKeys(Object[] keys)

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.

Specified by:

getKeysToLock in interface RemoteLockCommand

Overrides:

getKeysToLock in class InvalidateCommand

Returns:

a Collection of keys to lock.

writeTo

public void writeTo(ObjectOutput output)
             throws IOException

Description copied from interface: ReplicableCommand

Writes this instance to the ObjectOutput.

Specified by:

writeTo in interface ReplicableCommand

Overrides:

writeTo in class InvalidateCommand

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).

Specified by:

readFrom in interface ReplicableCommand

Overrides:

readFrom in class InvalidateCommand

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.

Specified by:

acceptVisitor in interface VisitableCommand

Overrides:

acceptVisitor in class InvalidateCommand

Parameters:

ctx - invocation context

visitor - visitor to accept

Returns:

arbitrary return value

Throws:

Throwable - in the event of problems

toString

public String toString()

Overrides:

toString in class InvalidateCommand

isCausedByALocalWrite

public boolean isCausedByALocalWrite(Address address)

Returns true if the write that caused the invalidation was performed on this node. More formal, if a put(k) happens on node A and ch(A)={B}, then an invalidation message might be multicasted by B to all cluster members including A. This method returns true if and only if the node where it is invoked is A.
