The context is the following: Update demo data by changing the values of all and every "date" fields. The goal is to avoid listeners to update creation/modif dates and contributors, to start workflows, to try to index text, ...
So, it would be nice to have something like:
someMainEventService.disableListeners(); . . . do the update someMainEventService.enableListeners()
Which must be more subtle than just disable/enable all: It must disable only the listeners that were already enabled, then re-enable them (and not enable all listeners including the one that were disabled before the call)
Some more detaile APIs/doc/explanation would be welcome. For example, here, I'm just changing dates. But if I wanted to bulk change text, how could I handle indexing?
The code I am working on (in a plug-in, not in the platform 
):
ArrayList<String> enabledListeners = new ArrayList<String>(); boolean wasBlockAsyncHandlers; boolean wasBlockSyncPostCommitHandlers; protected void disableListeners() { EventServiceImpl esi = (EventServiceImpl) Framework.getService(EventService.class); // Disable async. listeneres wasBlockAsyncHandlers = esi.isBlockAsyncHandlers(); wasBlockSyncPostCommitHandlers = esi.isBlockSyncPostCommitHandlers(); esi.setBlockAsyncHandlers(true); esi.setBlockSyncPostCommitHandlers(true); // Disable sync. ("inline") listeners: Get the list of active // listeners, disable each of them, then recompute the thing EventListenerList ell = esi.getListenerList(); ArrayList<EventListenerDescriptor> descs = new ArrayList<EventListenerDescriptor>(); descs.addAll(ell.getEnabledInlineListenersDescriptors()); for (EventListenerDescriptor d : descs) { enabledListeners.add(d.getName()); d.setEnabled(false); } ell.recomputeEnabledListeners(); } protected void restoreListeners() { EventServiceImpl esi = (EventServiceImpl) Framework.getService(EventService.class); esi.setBlockAsyncHandlers(wasBlockAsyncHandlers); esi.setBlockSyncPostCommitHandlers(wasBlockSyncPostCommitHandlers); EventListenerList ell = esi.getListenerList(); ArrayList<EventListenerDescriptor> descs = new ArrayList<EventListenerDescriptor>(); descs.addAll(ell.getInlineListenersDescriptors()); for (EventListenerDescriptor d : descs) { if (enabledListeners.contains(d.getName())) { d.setEnabled(true); } } ell.recomputeEnabledListeners(); }
