Interface UpdateManager

public interface UpdateManager

An update manager cooperates with update agents to automatically install updates to an application. All communication between the update agent and the update manager is asynchronous.

Implementations must be thread-safe.

Applications have no need to implement this class and should not do so because it may be subject to future expansion.
