addListener in interface DynamicConfiguration

Parameters:

key - the key to represent a configuration

group - the group where the key belongs to

listener - configuration listener

removeListener

public void removeListener(String key,
                           String group,
                           ConfigurationListener listener)

Description copied from interface: DynamicConfiguration

Stops one listener from listening to value changes in the specified key.

Specified by:

removeListener in interface DynamicConfiguration

Parameters:

key - the key to represent a configuration

listener - configuration listener

getConfig

public String getConfig(String key,
                        String group,
                        long timeout)
                 throws IllegalStateException
