Method Details

invokeAsync

public CompletionStage<org.infinispan.commons.util.IntSet> invokeAsync(ComponentRegistry registry)

Description copied from interface: CacheRpcCommand

Invoke the command asynchronously.

This method replaces ReplicableCommand.invoke() for remote execution. The default implementation and ReplicableCommand.invoke() will be removed in future versions.

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.

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

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.

getOrigin

public Address getOrigin()

Description copied from interface: CacheRpcCommand

Get the origin of the command

Specified by:

getOrigin in interface CacheRpcCommand

Overrides:

getOrigin in class BaseRpcCommand

setOrigin

public void setOrigin(Address origin)

Description copied from interface: CacheRpcCommand

Set the origin of the command

Specified by:

setOrigin in interface CacheRpcCommand

Specified by:

setOrigin in interface ReplicableCommand

Overrides:

setOrigin in class BaseRpcCommand

Parameters:

origin - the sender's Address

toString

public String toString()

Overrides:

toString in class BaseRpcCommand
