| <h2 id="Description">Description</h2> |
| <p>This |
| <i>JavaApplication</i> metamodel aims at weaving a MoDisco Java Model with a MoDisco KDM Inventory Model. It relies on the core metamodel described in the |
| |
| <a href="../../../org.eclipse.modisco.infrastructure.doc/mediawiki/kdm_source_extension/user.html">kdm.source extension framework</a>. |
| </p> |
| <p>Such a metamodel allows linking java nodes to their physical position in the source files ( |
| <i>JavaNodeSourceRegion</i> metaclass owning |
| <i>startLine</i>, |
| <i>endLine</i> properties). |
| </p> |
| <p>As proposed in the |
| <a href="../../../org.eclipse.modisco.infrastructure.doc/mediawiki/kdm_source_extension/user.html">kdm.source extension framework</a>, the reference |
| <i>JavaASTNodeSourceRegion.javaNode</i> derives from |
| <i>ASTNodeSourceRegion.node</i>. So does |
| <i>Java2File.javaUnit</i> from |
| <i>CodeUnit2File.unit</i>. |

| </p> |
| <p>Note : the references |
| <i>java2DirectoryChildren</i> and |
| <i>java2FileChildren</i> are expected to be containment references. For some technical reasons (memory usage tuning via lazy loading), they are not containments to make sure that the |
| <i>Java2Directory</i>, |
| <i>Java2File</i> and |
| <i>JavaNodeSourceRegion</i> instances are managed in their own graph compared with |
| <i>JavaApplication</i> instances (see |
| <a href="../../../org.eclipse.modisco.java.doc.archi/mediawiki/composition/archi.html#Benchmark">benchmark</a>). |
