Inheritance Relationships

Base Type

public eat::framework::DataPortBase (Class DataPortBase)

Class Documentation

template<typename T> class DataPort : public eat::framework::DataPortBase 

non-streaming data port for a specific type, T

T should be copyable and movable (value semantics), so that processes will not interact (i.e. see changes from non-upstream processes), and don’t have to copy manually

for heavy types (e.g. vector) it may be more efficient to use a smart pointer with const contents (like std::shared_ptr<const std::vector<…>>) to avoid copying unnecessarily

for types with RAII behaviour, readers should move from get_value to ensure that resources are freed as soon as possible

Public Functions

virtual bool compatible(const PortPtr &other) const override: are connections between this and other valid (i.e. the same type)

template<typename U> void set_value(U &&value): set the value — use this from a process for which this port is an output

const T &get_value() const: get the value — use this from a process for which this port is an input

T &get_value()

virtual void move_to(DataPortBase &other) override

virtual void copy_to(DataPortBase &other) override
