class ConnectionBase

Detailed Description

The base signal class which stores connection objects.

It implements real-time management of connections, such that connection/disconnetion of a handler is always thread-safe and real-time.

Definition at line 128 of file SignalBase.hpp.


Constructor & Destructor Documentation

Deletes this Signal and will destroy all connections and handles of this object.

It is not necessary to call disconnect() or disconnect() prior to destroying a SignalBase.

Definition at line 229 of file SignalBase.cpp.

References destroy().


Member Function Documentation

Destroys all connections.

This will destroy all connections of this Event. All Handles will be disconnected and unable to reconnect.

Disconnects all connections.

All Handles will be disconnected, but able to reconnect.

void RTT::internal::SignalBase::reserve ( size_t  conns)

Reserves memory for a number of connections.

Use this method to efficiently reserve memory for possible connections. If not used, the event will reserve memory in batch, depending upon demand. This does not impair/influence real-time performance, only memory efficiency.

Parameters:
connsThe number of connections to reserve memory for.
