Constructor Detail

AnySharedCountersImpl

public AnySharedCountersImpl(String name,
                             int type)

Create a facade with the specified name and transport type.

Parameters:

name - the name of the set of shared counters.

type - the transport type of the set of shared counters.

Method Detail

setRmiCounters

protected void setRmiCounters(RmiSharedCounters rmisc)

bind

public static SharedCounters bind(String name,
                                  int type,
                                  long[] initialValues)

Binds a fixed number of shared counters with the specified initial values in the location appropriate to the transport type (rmiregistry for RMI).

Parameters:

initialValues - the initial values for the counters.

lookup

public static SharedCounters lookup(String name,
                                    int type)

Looks up the shared counters in the location appropriate to the transport type (rmiregistry for RMI).

Returns:

the shared counters or null if not there.
