understanding wiring in BlockingAMSenderP

Dear all,

Thanks a bunch for all the help you have given me earlier.


Now i have come up with a new problem. :) I was going through BlockingAMSender interface in tosthreads. I'm not able to understand how wiring is done for AMSend in tosthreads. Here is the problem...


BlockingAMSenderImplP uses AMSend.

generic module BlockingAMSenderImplP() {
provides {
interface Init;
interface BlockingAMSend[am_id_t id];
}
uses {
interface SystemCall;
interface Mutex;
interface AMSend[am_id_t id];
interface Packet;
interface Leds;
}
}



& the corresponding configuration file for BlockingAMSenderImplP is BlockingAMSenderP which is as follows.


configuration BlockingAMSenderP {
provides {
interface BlockingAMSend[am_id_t amId];
}
uses {
interface AMSend[am_id_t amId];
}
}

implementation {
components MainC;
components ActiveMessageC as AM;
components new BlockingAMSenderImplP();
components MutexC;
components SystemCallC;
components LedsC;

MainC.SoftwareInit -> BlockingAMSenderImplP;

BlockingAMSend = BlockingAMSenderImplP;
AMSend = BlockingAMSenderImplP;
BlockingAMSenderImplP.Mutex -> MutexC;
BlockingAMSenderImplP.SystemCall -> SystemCallC;
BlockingAMSenderImplP.Packet -> AM;
BlockingAMSenderImplP.Leds -> LedsC;
}

I understand BlockingAMSend= BlockingAMSenderImplP , if i'm not wrong both (BlockingAMSenderImplP and BlockingAMSenderP) provide BlockingAMSend interface. But AMSend on the other hand is used by both BlockingAMSenderImplP and BlockingAMSenderP. But who is providing it?

i would be thankful if you can help me understand this.
