Interface IOptionsListener

All Known Implementing Classes:

CacheManagerImpl, ConfigImpl, DependenciesImpl

public interface IOptionsListener

Listener interface for options changes. To receive notification of options changes, register an instance of the implementing class as an OSGi service. The listener registration should specify a filter using the name property with the value obtained by calling IOptions.getName() for the options object who's changes you want to track.

Method Detail

optionsUpdated

void optionsUpdated(IOptions options,
                  long sequence)

This method is called when the options are loaded/changed.

Parameters:

options - The new options. Note that changes to the options may occur in-place, using the same IOptions object with updated values, or may result in a new object instance. This interface does not specify which approach is used by an implementation.

sequence - The sequence number. Notifications for different listener events (options, config, dependencies) that have the same cause have the same sequence number. The sequence number is incremented for subsequent event causes, but there is no guarantee about the the values for subsequent notifications other than that they will be increasing.
