Member Function Documentation

virtual void onExpiration ( const NetFeed &  )
pure virtual

Invoked by the feed engine machinery when the feed associated with the given consumer has reached its expiration time.

The expiration time for the feed is defined by the 'expirationTime' member.

The given member must be invoked only when the consumer was already successfully acquired.

virtual void onFailure ( const NetFeed &  ,
const Char *   
)
pure virtual

Invoked by the feed engine machinery when it experienced an issue while receiving data for the feed associated with the given consumer.

The given member must be invoked only when the consumer was already successfully acquired.

virtual void onPacket ( const NetPacket &  )
pure virtual

Invoked by the feed engine machinery when a packet is received for the feed associated with the given consumer.

The given member must be invoked only when the consumer was already successfully acquired.

virtual void onTimeout ( const NetFeed &  )
pure virtual

Invoked by the feed engine machinery when any packet wasn't received for the feed associated with the given consumer for a predefined amount of time.

The given member must be invoked only when the consumer was already successfully acquired.

virtual void release ( )
pure virtual

Releases previously acquired consumer.

virtual bool tryAcquire ( )
pure virtual

Tries to gain access to the given consumer.

Before invoking any other member, the consumer must be successfully acquired. This is because the consumer may be busy while handling the other event from the other source.
