Method Details

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.

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

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.

Specified by:

supportedSince in interface ReplicableCommand

Specified by:

supportedSince in interface VersionAware

Overrides:

supportedSince in class InvalidateCommand

Returns:

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

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.
