Detailed Description

Define the interface for the connect strategy, i.e. the algorithm that controls how does the ORB establishes remote connections.

The thread that establishes remote connections can either make a blocking or a non-blocking connect. The strategy to wait for the connection completion can also be different.

This strategy controls how does the ORB schedules and waits for connection completion.

int TAO_Connect_Strategy::poll

(

TAO_LF_Multi_Event *

ev

)

Do a quick check to see if any connections are complete. This does the same as the wait with an explicit time value of 0.
