Method Detail

init

public void init(InterceptorChain chain,
                 InvocationContextContainer icc,
                 TransactionTable txTable)

getCacheName

public String 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.

setCacheName

public void setCacheName(String cacheName)

getGlobalTransaction

public GlobalTransaction getGlobalTransaction()

Specified by:

getGlobalTransaction in interface TransactionBoundaryCommand

perform

public Object perform(InvocationContext ctx)
               throws Throwable

Description copied from interface: ReplicableCommand

Performs the primary function of the command. Please see specific implementation classes for details on what is performed as well as return types. Important: this method will be invoked at the end of interceptors chain. It should never be called directly from a custom interceptor.

Specified by:

perform in interface ReplicableCommand

Parameters:

ctx - invocation context

Returns:

arbitrary return value generated by performing this command

Throws:

Throwable - in the event of problems.

getParameters

public Object[] getParameters()

Description copied from interface: ReplicableCommand

Used by marshallers to stream this command across a network

Specified by:

getParameters in interface ReplicableCommand

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 interface: ReplicableCommand

Used by the CommandsFactory to create a command from raw data read off a stream.

Specified by:

setParameters in interface ReplicableCommand

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

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 Object
