# clang-uml - UML diagram generator based on Clang and PlantUML

clang-uml is an automatic PlantUML class and sequence diagram generator, driven by
YAML configuration files. The main idea behind the project is to easily
maintain up-to-date diagrams within a code-base.  The configuration file or
files for clang-uml define the type and scope of each diagram.

| Association (A knows of B)   | Class A has a pointer or a reference to class B, or any container with a pointer or reference to B |
| Dependency (A uses B)        | Any method of class A has argument of type B                                                       |
| Aggregation (A has B)        | Class A has a field of type B or an owning pointer of type B                                       |
| Composition (A has B)        | Class A has a field of type container of B                                                         |
| Template (T specializes A)   | Class A has a template parameter T                                                                 |
| Nesting (A has inner class B)| Class B is an inner class of A
