Interface Stability

All Known Implementing Classes:

StabilityComputation

public interface Stability

An interface to check the stability of the running application.

Theoretically, the architecture of a dynamic system is considered as stable when there are no change in progress. This concept is useful to determine when the system as complete its startup sequence, but also important ofter any deployment action that may have change the underlying architecture.

The stability service is implemented by Chameleon itself, but is made to be extended so the application can contribute StabilityChecker to extend the stability computation.

Be aware that stability computation is blocking the caller thread.

Method Summary

Modifier and Type	Method and Description
Map<StabilityChecker,StabilityResult>	getStabilityResult() Checks and retrieve the individual stability check result.
boolean	isStable() Checks whether the current framework is stable or not.

Method Detail

isStable

boolean isStable()

Checks whether the current framework is stable or not. Be aware that this method blocks the calling thread until stability is reached.

Returns:

true if the stability is reached, false otherwise.

getStabilityResult

Map<StabilityChecker,StabilityResult> getStabilityResult()

Checks and retrieve the individual stability check result.

Returns:

the results. The returned map is ordered.
