bool EventConsumerSelector::acceptEvent

(

const I2OChain &

ioc

)

Tests whether the specified event is accepted by this selector - returns true if the event is accepted, false otherwise.

void EventConsumerSelector::initialize

(

const InitMsgView &

imv

)

Initializes the selector instance from the specified INIT message. EventConsumerSelector instances need to be initialized before they will accept any events.
