Class TestingInApplicationMonitor

java.lang.Object

de.is24.util.monitoring.InApplicationMonitor

de.is24.util.monitoring.TestingInApplicationMonitor

public class TestingInApplicationMonitor
extends InApplicationMonitor

This is a helper class for testing appmon4j integration. For example it allows a clean initialization of the InApplicationMonitor instance in a setup @before method. This class partially exposes methods, usually not available, and thus should not be used in production code. Especially as this code may induce concurrence problems in a multi threading environment.

getPlugins

Overrides:

setThreadLocalState

public void setThreadLocalState()

this method allows Tests running multi threaded to achieve some level of isolation against activities from other threads. All methods handed over to the CorePlugin will be handled by a dedicated CorePlugin instance for the calling thread, and all threads created by this thread. So this is currently only helpfull for StateValueProviders, MultiValueProviders and Versions. This core plugin will even "survive" calls to @seet resetInstanceForTesting or @see initInstanceForTesting calls in other threads. The dedicated CorePlugin will not be accessible via JMX, only the original CorePlugins data will be available via JMX.

Overrides:

resetThreadLocalState

public void resetThreadLocalState()
