Constructor Detail

PluginState

public PluginState(com.atlassian.event.api.EventPublisher eventPublisher,
                   LandlordRequests landlordRequests)

Method Detail

onPluginFrameworkDelayed

@EventListener
public void onPluginFrameworkDelayed(com.atlassian.plugin.event.events.PluginFrameworkDelayedEvent event)

Listens for a PluginFrameworkDelayedEvent - this is fired by the plugin system when earlyStartup has completed. i.e. the host containing the plugin system can be considered to be "WARM" and thus calls to query for tenant state now make sense.

Parameters:

event - The PluginFrameworkDelayedEvent sent by the plugin system

onPluginEnabledEvent

@EventListener
public void onPluginEnabledEvent(com.atlassian.plugin.event.events.PluginEnabledEvent event)

Listens for PluginEnabledEvent and sets pluginSystemReady to true if the host application is tenanted. We need to do this because the plugin may be DE installed at any time and there won't be a PluginFrameworkDelayedEvent Note that this is only a short term solution as in the future we may start upgrading plugins in the warm pool and of course they will not be tenanted

Parameters:

event - The PluginEnabledEvent sent by plugin system

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

pluginSystemReady

public boolean pluginSystemReady()
