class Component

Base class for all components.

This class is the base class for all components including holoscan::Operator, holoscan::Condition, and holoscan::Resource. It is used to define the common interface for all components.

Subclassed by holoscan::Condition, holoscan::NetworkContext, holoscan::Operator, holoscan::Resource, holoscan::Scheduler

Public Functions

Component() = default

template<typename ArgT, typename ...ArgsT, typename = std::enable_if_t<!std::is_base_of_v<Component, std::decay_t<ArgT>> && (std::is_same_v<Arg, std::decay_t<ArgT>> || std::is_same_v<ArgList, std::decay_t<ArgT>>)>>
inline explicit Component(ArgT &&arg, ArgsT&&... args)

Construct a new Component object.

Parameters

virtual ~Component() = default

inline int64_t id() const

Get the identifier of the component.

By default, the identifier is set to -1. It is set to a valid value when the component is initialized.

With the default executor (GXFExecutor), the identifier is set to the GXF component ID.

Returns

inline const std::string &name() const

Get the name of the component.

Returns

inline Fragment *fragment()

Get a pointer to Fragment object.

Returns

inline void add_arg(const Arg &arg)

Add an argument to the component.

Parameters

inline void add_arg(Arg &&arg)

Add an argument to the component.

Parameters

inline void add_arg(const ArgList &arg)

Add a list of arguments to the component.

Parameters

inline void add_arg(ArgList &&arg)

Add a list of arguments to the component.

Parameters

inline std::vector<Arg> &args()

Get the list of arguments.

Returns

inline virtual void initialize()

virtual YAML::Node to_yaml_node() const

Get a YAML representation of the component.

Returns

std::string description() const

Get a description of the component.

Returns
