Since 9.2, please use invokeCommand(Collection, ReplicableCommand, ResponseCollector, DeliverOrder, long, TimeUnit) instead.

Invokes an RPC call on other caches in the cluster.

Parameters:

recipients - a list of Addresses to invoke the call on. If this is null, the call is broadcast to the entire cluster.

rpcCommand - the cache command to invoke

mode - the response mode to use

timeout - a timeout after which to throw a replication exception. implementations.

responseFilter - a response filter with which to filter out failed/unwanted/invalid responses.

deliverOrder - the DeliverOrder.

anycast - used when {@param totalOrder} is true, it means that it must use TOA instead of TOB.

a map of responses from each member contacted.

Throws:

Exception - in the event of problems.

isCoordinator

boolean isCoordinator()

Returns:

true if the current Channel is the coordinator of the cluster.

getCoordinator

Address getCoordinator()

Returns:

the Address of the current coordinator.

getAddress

Address getAddress()

Retrieves the current cache instance's network address

Returns:

an Address

getPhysicalAddresses

List<Address> getPhysicalAddresses()

Retrieves the current cache instance's physical network addresses. Some implementations might differentiate between logical and physical addresses in which case, this method allows clients to query the physical ones associated with the logical address. Implementations where logical and physical address are the same will simply return a single entry List that contains the same Address as getAddress().

Returns:

an List of Address

getMembers

List<Address> getMembers()

Returns a list of members in the current cluster view.

Returns:

a list of members. Typically, this would be defensively copied.

isMulticastCapable

boolean isMulticastCapable()

Tests whether the transport supports true multicast

Returns:

true if the transport supports true multicast

start

void start()

Description copied from interface: Lifecycle

Invoked on component start

Specified by:

start in interface Lifecycle

stop

void stop()

Description copied from interface: Lifecycle

Invoked on component stop

Specified by:

stop in interface Lifecycle

getViewId

int getViewId()

Throws:

CacheException - if the transport has been stopped.

withView

CompletableFuture<Void> withView(int expectedViewId)

Returns:

A CompletableFuture that completes when the transport has installed the expected view.

waitForView

@Deprecated
void waitForView(int viewId)
          throws InterruptedException

Deprecated.

Since 9.0, please use withView(int) instead.

Throws:

InterruptedException

getLog

checkTotalOrderSupported

void checkTotalOrderSupported()

check if the transport has configured with total order deliver properties (has the sequencer in JGroups protocol stack.

getSitesView

Set<String> getSitesView()

Get the view of interconnected sites. If no cross site replication has been configured, this method returns null. Inspecting the site view can be useful to see if the different sites have managed to join each other, which is pre-requisite to get cross replication working.

Returns:

set containing the connected sites, or null if no cross site replication has been enabled.

Invoke a command on a collection of nodes and pass the responses to a ResponseCollector.

The command is only sent immediately to the first target, and there is an implementation-dependent delay before sending the command to each target. There is no delay if the target responds or leaves the cluster. The remaining targets are skipped if ResponseCollector.addResponse(Address, Response) returns a non-null value.
