176
|
|
|
|
|

|
|
|
|
|
|
|
PlantUML::ClassDiagram::Parse is parser for PlantUML class diagram syntax |
178
|
|
|
|
|
|
|
It generate objects that represent class structure written in class diagram. |

=head2 WAY TO USE |
181
|
|
|
|
|
|
|
|
182
|
|
|
|
|
|
|
Generate perl module using PlantUML::ClassDiagram::Class objects. |
183
|
|
|
|
|
|
|
In fact you will also use template engine (ex: Text::Xslate) together. |
184
|
|
|
|
|

|
|
|
|
|
|
