Constructor & Destructor Documentation

Edge()

template<typename Thing1, typename Thing2>

Edge ( Thing1 && h, Thing2 && t )

inline

This constructor creates a new Edge object with head h (converted to a std::string using std::to_string if thing is not already a std::string, std::string_view, or char const*) and tail t (similarly converted to a std::string).

The newly constructed Edge has no attributes set.

Template Parameters

Thing

the type of the argument.

Parameters

h	the head of the edge.
t	the tail of the edge.

Member Function Documentation

add_attr()

template<typename Thing1, typename Thing2>

Edge & add_attr ( Thing1 && key, Thing2 && val )

inline

This function adds a new attribute, or replaces the value of an existing attribute of an Edge. The arguments key and val are converted to std::string (unless they are std::string, std::string_view, or char const* already).

Template Parameters

Thing1	the type of the first argument.
Thing2	the type of the second argument.

Parameters

key	the name of the attribute.
val	the value of the attribute.

Returns

A reference to this.

Warning

No checks of any kind are performed that the string representations of key or val are valid in DOT; see the Graphviz documentation for more details.

Friends And Related Symbol Documentation

to_human_readable_repr()

std::string to_human_readable_repr ( Dot::Edge const & e )

related

Return a human readable representation of a Dot::Edge object.

Parameters

e	the Dot::Edge object.

Exceptions

This function guarantees not to throw a LibsemigroupsException.
