Enclosing class:

RemoteUsage

public static class RemoteUsage.UsageReader
extends Object

Helps obtaining usage parameters by name.

• RemoteUsage.Subsystems.getUsageReader(javax.management.MBeanServerConnection, String, String)

• RemoteUsage.Sbbs.getUsageReader(javax.management.MBeanServerConnection, javax.slee.ServiceID, javax.slee.SbbID, String)

• RemoteUsage.Profiles.getUsageReader(javax.management.MBeanServerConnection, String, String)

• RemoteUsage.Resources.getUsageReader(javax.management.MBeanServerConnection, String, String)
