orcaice::Context Class Reference Component's naming and networking information. More... #include <context.h> List of all members. Public Member Functions const std::string &  tag () const   Component's tag used in configuration files. const orca::FQComponentName &  name () const   Component's fully-qualified name given to the Registry. bool  isApplication () const   Is this component executed inside and application or a service? Returns TRUE if this instance of the Component is used in a stand-alone application. Otherwise, returns FALSE, meaning that it's used inside an IceBox service. Ice::CommunicatorPtr  communicator () const   Returns smart pointer to the component's communicator. Ice::ObjectAdapterPtr  adapter () const   Returns smart pointer to the component's adapter. Ice::PropertiesPtr  properties () const orcaice::Home &  home () const   Access to setting home information. gbxsickacfr::gbxutilacfr::Tracer &  tracer () const   Access tracing functions. gbxsickacfr::gbxutilacfr::Status &  status () const   Access status functions. hydroutil::History &  history () const   Access history functions. void  activate () void  shutdown ()   Triggers component shutdown. hydroutil::Context  toHydroContext (const std::string &prefixToStrip) const hydroutil::Context  toHydroContext () const Detailed Description Component's naming and networking information. Contains pointers to component's registered name plus its communicator, adapter, etc. It makes it easy to pass all this information to the network and hardware handlers from the class derived from Component. A note on thread safety. None of access functions are thread-safe. However, all object which are referenced (with pointers and smart pointers) are themselves thread-safe. This means that once a copy of of Context is created, it is safe to use it from different threads. Pass context by const reference and store a copy, e.g. a class definition would look like this: class MyClass { public: MyClass( const orcaice::Context & context ) : context_(context) {}; private: orcaice::Context context_; } Member Function Documentation void orcaice::Context::activate (   )    Actiates server functionality of the component. This function is useful when component activation (technically Ice::ObjectAdapter activation) must be delayed until after something is initialized in the child thread. Ice::PropertiesPtr orcaice::Context::properties (   )  const [inline]   Convenience function which returns smart pointer to the component's properties. Same as calling communicator()->getProperties() hydroutil::Context orcaice::Context::toHydroContext (   )  const   Conveniance function which is a shortcut for the function above with prefixToStrip = tag()+".Config." hydroutil::Context orcaice::Context::toHydroContext (  const std::string &  prefixToStrip  )  const   Repackages itself into the form useful for initializing Hydro drivers. Strips 'prefixToStrip' from the front of all properties. Does not copy properties which do not begin with prefixToStrip. Transfers the following config parameters from Orca configs to Hydro configs: Orca.Warn.DefaultProperty The documentation for this class was generated from the following files: context.h context.cpp
