Constructor Detail

PutDataMapCommand

public PutDataMapCommand(GlobalTransaction globalTransaction,
                         Fqn fqn,
                         Map data)

PutDataMapCommand

public PutDataMapCommand()

Method Detail

perform

public Object perform(InvocationContext ctx)

Adds the provided data map to the data map in the node referenced by the specified Fqn.

Parameters:

ctx - invocation context

Returns:

arbitrary return value generated by performing this command

rollback

public void rollback()

Description copied from interface: ReversibleCommand

Reverses a command that has already been invoked. Important: this method will be invoked at the end of interceptors chain. It should never be called directly from a custom interceptor.

acceptVisitor

public Object acceptVisitor(InvocationContext ctx,
                            Visitor visitor)
                     throws Throwable

Description copied from interface: VisitableCommand

Accept a visitor, and return the result of accepting this visitor.

Parameters:

ctx - invocation context

visitor - visitor to accept

Returns:

arbitrary return value

Throws:

Throwable - in the event of problems

getData

public Map getData()

setData

public void setData(Map data)

getCommandId

public int 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.

getParameters

public Object[] getParameters()

Description copied from class: AbstractDataCommand

Basic versions of these methods

Specified by:

getParameters in interface ReplicableCommand

Overrides:

getParameters in class AbstractVersionedDataCommand

Returns:

an object array of arguments, compatible with pre-2.2.0 MethodCall args.

setParameters

public void setParameters(int commandId,
                          Object[] args)

Description copied from class: AbstractDataCommand

Basic versions of these methods

Specified by:

setParameters in interface ReplicableCommand

Overrides:

setParameters in class AbstractVersionedDataCommand

Parameters:

commandId - command id to set. This is usually unused but *could* be used in the event of a command having multiple IDs, such as PutKeyValueCommand.

args - object array of args

isVersionedId

protected boolean isVersionedId(int id)

Specified by:

isVersionedId in class AbstractVersionedDataCommand

equals

public boolean equals(Object o)

Overrides:

equals in class AbstractVersionedDataCommand

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractVersionedDataCommand

toString

public String toString()

Overrides:

toString in class AbstractDataCommand
