Package org.infinispan.commands.remote

Class ClusteredGetCommand

java.lang.Object

org.infinispan.commands.remote.BaseRpcCommand

org.infinispan.commands.remote.BaseClusteredReadCommand

org.infinispan.commands.remote.ClusteredGetCommand

All Implemented Interfaces:

CacheRpcCommand, ReplicableCommand, SegmentSpecificCommand, TopologyAffectedCommand

public class ClusteredGetCommand
extends BaseClusteredReadCommand
implements SegmentSpecificCommand

Issues a remote get call. This is not a VisitableCommand and hence not passed up the interceptor chain.

Method Details

invokeAsync

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

Invokes a logical "get(key)" on a remote cache and returns results.

Specified by:

invokeAsync in interface CacheRpcCommand

Returns:

Throws:

Throwable

getGlobalTransaction

@Deprecated
public GlobalTransaction getGlobalTransaction()

Deprecated.

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.

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.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class BaseRpcCommand

isWrite

public boolean isWrite()

setWrite

public void setWrite(boolean write)

getSegment

public int getSegment()

Description copied from interface: SegmentSpecificCommand

Returns the segment that this key maps to. This must always return a number 0 or larger.

Specified by:

getSegment in interface SegmentSpecificCommand

Returns:

the segment of the key

getKey

public Object getKey()

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
