Method Detail

getInterestedEventTypes

public java.lang.Class[] getInterestedEventTypes()

Description copied from interface: RegisterableTriggerInterface

Get the event classes that the trigger is interested in seeing. This is an optimization, so that a trigger's processEvent() method is called only when a valid event occurs.

Specified by:

getInterestedEventTypes in interface RegisterableTriggerInterface

Returns:

an array of Class objects which implement the 'Event' interface

See Also:

RegisterableTriggerInterface.getInterestedEventTypes()

getInterestedInstanceIDs

public java.lang.Integer[] getInterestedInstanceIDs(java.lang.Class c)

Description copied from interface: RegisterableTriggerInterface

Get a list of instance IDs specific to a class (as returned by getInterestedEventTypes) which the trigger is interested in seeing. These values are specific to the event type, and represent things such as specific measurements.

Specified by:

getInterestedInstanceIDs in interface RegisterableTriggerInterface

Parameters:

c - Class to get the interested event IDs for

Returns:

An array of integers representing the instance IDs for the specific event class

See Also:

RegisterableTriggerInterface.getInterestedInstanceIDs(java.lang.Class)

getConfigSchema

public ConfigSchema getConfigSchema()

Description copied from interface: ConditionalTriggerInterface

Return the schema for the configuration of this trigger. This does not actually get called by anyone, it's here to enforce the authors of triggers to implement getConfigSchema() for the CLI.

Specified by:

getConfigSchema in interface ConditionalTriggerInterface

Specified by:

getConfigSchema in interface RegisterableTriggerInterface

See Also:

RegisterableTriggerInterface.getConfigSchema()

getConfigResponse

public ConfigResponse getConfigResponse(AppdefEntityID id,
                                        AlertConditionValue cond)
                                 throws InvalidOptionException,
                                        InvalidOptionValueException

Description copied from interface: ConditionalTriggerInterface

Translate alert condition to config response object

Specified by:

getConfigResponse in interface ConditionalTriggerInterface

cond - the alert condition

Returns:

the equivalent config response object

Throws:

InvalidOptionException

InvalidOptionValueException

See Also:

org.hyperic.hq.bizapp.server.trigger.conditional.ConditionalTriggerInterface#getConfigResponse()

init

public void init(RegisteredTriggerValue tval,
                 AlertConditionEvaluator alertConditionEvaluator)
          throws InvalidTriggerDataException

Description copied from interface: RegisterableTriggerInterface

Initialize the trigger with a value object.

Specified by:

init in interface RegisterableTriggerInterface

Parameters:

tval - The trigger data object containing all the configuration data

alertConditionEvaluator - The evaluator to use for reporting trigger fired/trigger not fired events

Throws:

InvalidTriggerDataException - if the configuration data is invalid.

org.hyperic.hq.events.ext.RegisterableTriggerInterface#init(org.hyperic.hq.events.shared.RegisteredTriggerValue)

processEvent

public void processEvent(AbstractEvent e)
                  throws EventTypeException

Description copied from interface: TriggerInterface

Process an event from the dispatcher.

Specified by:

processEvent in interface TriggerInterface

Parameters:

e - the Event to process

Throws:

EventTypeException - if the trigger does not process events of the type provided
