Method Detail

invokeAsync

public CompletionStage<?> invokeAsync(ComponentRegistry registry)
                               throws Throwable

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.

Specified by:

invokeAsync in interface CacheRpcCommand

Throws:

Throwable

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

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.

Specified by:

isReturnValueExpected in interface ReplicableCommand

Returns:

true or false

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

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

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.

getCacheName

public ByteString getCacheName()

Specified by:

getCacheName in interface CacheRpcCommand

Returns:

the name of the cache that produced this command. This will also be the name of the cache this command is intended for.

getOrigin

public Address getOrigin()

Description copied from interface: CacheRpcCommand

Get the origin of the command

Specified by:

getOrigin in interface CacheRpcCommand

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

Parameters:

origin - the sender's Address

toString

public String toString()

Overrides:

toString in class Object
