 ====== Module ======
-Module are base nodes used in model. They extends [[https://javadoc.grogra.de/graph/de/grogra/graph/impl/Node.html|Node]] by default, but can extend another object if specified.
+Modules are base nodes used in XL models. They extends [[https://javadoc.grogra.de/graph/de/grogra/graph/impl/Node.html|Node]] by default, but can extend another object if specified. To be used in a project modules are classes defined with:
+  - A public constructor with all its fields as variables
+  - Fields for each of the module [[:01_user_documentation:06_graph:02_node:01_attribute|attributes]]
+  - Accessor methods for these fields
+  - A [[:01_user_documentation:07_rgg_xl:02_xl:03_query:01_predicate:01_node:02_parametrized|parametrized pattern]] with all of its attributes as variable

-===== Constructor =====
-Additionally modules are created with a default constructor (aka a way for groimp to create them without parameters)
-e.g. module A(int len) {} can be added in a production rule with A(), A, A(1), ...
-===== Pattern =====
-Module are also compiled with a default pattern. e.g. they can be added in predicate with an attribute pattern:
-(with the same A as before)
-[ A(x, y) ==>  ;]
-x will be the instanceof the A, and y, the (int) len.
