Detailed Description

Functionality for disconnecting the various references that objects make to each other.

This class is a wrapper around a boost::signal2 which guarantees that each attached function is run once and only once.

Constructor & Destructor Documentation

makVrv::DtDisconnectable::DtDisconnectable

(

)

Default constructor.

virtual makVrv::DtDisconnectable::~DtDisconnectable ( )

virtual

Destructor.

callDisconnectFunctions is not called in the destructor, it is up to to the caller to call it when it is necessary.

Member Function Documentation

virtual boost::signals2::connection makVrv::DtDisconnectable::addDisconnectFunction ( const boost::function< void()> &  callback )

virtual

Add a function to be called when callDisconnectFunctions is called.

If it has already been called, then the callback will be called during this call.

virtual bool makVrv::DtDisconnectable::callDisconnectFunctions ( )

virtual

Atomically call all the disconnect functions and mark this object as disconnected.

If callDisconnectFunctions has already been called or is currently being called, this call will do nothing.
