Interface StabilityChecker

All Known Implementing Classes:

AbstractStabilityChecker, BundleStabilityChecker, IPojoProcessingStabilityChecker, ServiceStabilityChecker

public interface StabilityChecker

Service exposed to extend the stability computation. All provider exposing this service are involved in the stability computation. The priority of each checker lets order the check in a sequence. Low priority are executed first, while higher priority are executed at the end of the computation.

Be pretty careful when implementing this service:

• The process (check()) tries to reach the stability criteria
• The caller thread is blocked, so fail the stability after a reasonable timeout
