API Reference

PlantUML Interface

StartUml() UML

Start a new UML diagram and returns its implementation.

uml := puml.StartUml()

UML Interface

Title(title string) UML

Adds a title to the diagram.

uml.Title("The UML Diagram")

Skinparam(param string, value string) UML

Adds a Skinparam to the diagram.

uml.Skinparam("responseMessageBelowArrow", "true")

Participant(displayName string, name string) UML

Adds a new Participant to the diagram.

uml.Participant("Service", "srv")

It will translate in puml as: participant Service as srv

ArrowR(from string, to string, msg string) UML

Adds an arrow to the diagram.

uml.ArrowR("srv1", "srv2", "msg")

It will translate in puml as: srv1->srv2: msg

ArrowL(from string, to string, msg string) UML

Adds an arrow with style to the diagram

uml.ArrowL("srv1", "srv2", "msg")

It will translate in puml as: srv1<-srv2: msg

String() string

Returns the UML diagram as string representation. Understands this method as Marshal.

diagram := uml.String()
