Detailed Description

A sender.

This is a role class, so real senders need to inherit from it.

Constructor & Destructor Documentation

Sender::Sender ( const Global_id & id,

int

) [inline, explicit, protected]

Optimized constructor.
This constructor assumes that the object storage is zero-initialized.
Parameters:

id user-visible thread ID of the sender

ignored an integer argument. The value doesn't matter and is used just to distinguish this constructor from the default one.

Sender::Sender ( const Global_id & id ) [inline, protected]

Constructor.

Parameters:

id user-visible thread ID of the sender

Member Function Documentation

Global_id Sender::id ( ) const [inline]

Sender ID.

Returns:
user-visible thread ID of the sender

bool Sender::in_sender_list ( ) [inline]

Sender in a queue of senders?.

Returns:
true if sender has enqueued in a receiver's list of waiting senders

virtual void Sender::ipc_receiver_ready ( ) [pure virtual]

Receiver-ready callback.
Receivers make sure to call this function on waiting senders when they get ready to receive a message from that sender. Senders need to overwrite this interface.
Implemented in Irq, Preemption, and Thread.

Receiver * Sender::receiver ( ) const [inline]

Current receiver.

Returns:
receiver this sender is currently trying to send a message to.

void Sender::sender_dequeue ( Sender ** r ) [inline]

Dequeue from a sender list.

Parameters:

r pointer to sender-list head.

void Sender::sender_enqueue ( Sender ** r ) [inline, protected]

Enqueue in a sender list.

Parameters:

r pointer to sender-list head.

void Sender::set_receiver ( Receiver * receiver ) [inline, protected]

Set current receiver.

Parameters:

receiver the receiver we're going to send a message to

Reimplemented in Preemption.
