init
public void init(DataContainer dataContainer, OrderedUpdatesManager orderedUpdatesManager, StateTransferLock stateTransferLock, DistributionManager distributionManager, BiasManager biasManager)
-
invokeAsync
public CompletableFuture<Object> invokeAsync()
Description copied from interface:ReplicableCommand
Invoke the command asynchronously.This method replaces
ReplicableCommand.perform(InvocationContext)
for remote execution. The default implementation andReplicableCommand.perform(InvocationContext)
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 remoteResponseGenerator
may choose to simply return null to save on marshalling costs.- Returns:
- true or false
-
canBlock
public boolean canBlock()
Description copied from interface:ReplicableCommand
If true, the command is processed asynchronously in a thread provided by an Infinispan thread pool. Otherwise, the command is processed directly in the JGroups thread. This feature allows to avoid keep a JGroups thread busy that can originate discard of messages and retransmissions. So, the commands that can block (waiting for some state, acquiring locks, etc.) should return true.- Specified by:
canBlock
in interfaceReplicableCommand
- Overrides:
canBlock
in classBaseRpcCommand
- Returns:
true
if the command can block/wait,false
otherwise
-
writeTo
public void writeTo(ObjectOutput output) throws IOException
Description copied from interface:ReplicableCommand
Writes this instance to theObjectOutput
.- 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 byReplicableCommand.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.
-
toString
public String toString()
- Overrides:
toString
in classBaseRpcCommand
