Classes🔗

	Name
class	iox::popo::ChunkSender
class	iox::popo::Client The Client class for the request-response messaging pattern in iceoryx.
struct	iox::popo::ClientOptions This struct is used to configure the client.
class	iox::popo::ListenerImpl The Listener is a class which reacts to registered events by executing a corresponding callback concurrently. This is achieved via an encapsulated thread inside this class.
class	iox::popo::Listener
class	iox::popo::NotificationAttorney Class which allows accessing private methods to friends of NotificationAttorney. Used for example by the WaitSet. Implements the Client-Attorney Pattern.
struct	iox::popo::EventCallback
struct	iox::popo::NotificationCallback the struct describes a callback with a user defined type which can be attached to a WaitSet or a Listener
class	iox::popo::NotificationInfo NotificationInfo holds the state of a trigger like the pointer to the triggerOrigin, the notification id and the callback.
class	iox::popo::Publisher The Publisher class for the publish-subscribe messaging pattern in iceoryx.
struct	iox::popo::PublisherOptions This struct is used to configure the publisher.
class	iox::popo::RpcInterface
class	iox::popo::Request The Request class is a mutable abstraction over types which are written to loaned shared memory. These requests are sent to the server via the iceoryx system.
class	iox::popo::Response The Response class is a mutable abstraction over types which are written to loaned shared memory. These responses are sent to the client via the iceoryx system.
class	iox::popo::RpcBaseHeader
class	iox::popo::RequestHeader
class	iox::popo::ResponseHeader
class	iox::popo::PublisherInterface
class	iox::popo::Sample The Sample class is a mutable abstraction over types which are written to loaned shared memory. These samples are publishable to the iceoryx system.
class	iox::popo::Server The Server class for the request-response messaging pattern in iceoryx.
struct	iox::popo::ServerOptions This struct is used to configure the server.
class	iox::popo::Subscriber The Subscriber class for the publish-subscribe messaging pattern in iceoryx.
struct	iox::popo::SubscriberOptions This struct is used to configure the subscriber.
struct	iox::popo::StateBasedTrigger_t
struct	iox::popo::EventBasedTrigger_t
class	iox::popo::Trigger The Trigger class is usually managed by a factory class like a WaitSet and acquired by classes which would like to signal a notification. Multiple Trigger can share a common ConditionVariableData pointer so that multiple Trigger can signal a single instance.
class	iox::popo::TriggerHandle TriggerHandle is threadsafe without restrictions in a single process. Not qualified for inter process usage. The TriggerHandle is generated by a Notifyable like the WaitSet and handed out to the user when they acquire a trigger. The TriggerHandle corresponds with an internal Trigger and is used to signal an event via the trigger method. When it goes out of scope it cleans up the corresponding trigger in the Notifyable.
class	iox::popo::UntypedClient
class	iox::popo::UntypedPublisher The UntypedPublisher class for the publish-subscribe messaging pattern in iceoryx.
class	iox::popo::UntypedServer
class	iox::popo::UntypedSubscriber The UntypedSubscriber class for the publish-subscribe messaging pattern in iceoryx.
class	iox::popo::UserTrigger An event based trigger which can be used by the application developer directly. If you would like to trigger a WaitSet/Listener through an event of your class you should use the Trigger class.
class	iox::popo::WaitSet Logical disjunction of a certain number of Triggers.
