public interface Observer

Observer for consuming events.

Field Summary

Fields

Modifier and Type	Field	Description
static int	MAX_PRIORITY	Maximum priority.
static int	MIN_PRIORITY	Minimum priority.

Method Summary

Modifier and Type	Method	Description
int	getPriority(Event event)	Retrieves the priority to observe this event. This can be used to process a supported event before others observers.
void	observe(Event event, Map<String,Object> transientVars)	Observes an event.
boolean	supports(Event event)	Checks if the event is supported.

Field Detail

MIN_PRIORITY

static final int MIN_PRIORITY

Method Detail

supports

boolean supports(Event event)

Checks if the event is supported. If true, the observe(Event) method will be called.

Parameters:

event - the event.

Returns:

true for observing this event, false otherwise.

getPriority

int getPriority(Event event)

Retrieves the priority to observe this event.
This can be used to process a supported event before others observers.

Parameters:

event - the event.

Returns:

the priority where 0 the max priority and Integer.MAX_VALUE the min priority.

observe

void observe(Event event,
             Map<String,Object> transientVars)
      throws Exception

Observes an event.

Parameters:

event - the event.

transientVars - transientVars passed from one Observer to another when processing a single Event. This may allow optimizations between observers.

Throws:

Exception - if an error occurs. All exceptions will be logged but not propagated, as the observation mechanism should never fail.
