Method Detail

getEventType

@NotNull
public String getEventType()

Description copied from interface: EventPoller

Returns the type of event (i.e. the EventDefinition name) that this poller checks for.

Specified by:

getEventType in interface EventPoller

Returns:

the type of event (i.e. the EventDefinition name) that this poller checks for

getSourceLocation

@NotNull
public String getSourceLocation()

poll

@Nullable
public Set<Event> poll()

Description copied from interface: EventPoller

Poll for new Events (i.e. Events that have occurred since the last time poll() was called).

Specified by:

poll in interface EventPoller

Returns:

any new Events (i.e. Events that have occurred since the last time poll() was called)

init

protected void init()

This performs any initialization that requires using the EventContext. It must *not* be called from our constructor, because pollers are constructed during PC initialization, and at that time the PC EventManager, which the EventContext relies on, is not yet available. Instead it is called from poll() on the first invocation of that method, at which point the PC will be initialized.
