      Constructs a new ClasspathModelKnowledge instance.

  • Method Details

    • createKnowledge

      public void createKnowledge(boolean force) throws Exception
      Creates the knowledge base, with an option to force recreation.
      Parameters:
      force - true to force recreation of the knowledge base.
      Throws:
      Exception - if an error occurs during creation.

    • addPackages

      public void addPackages(Collection<Package> packages)
      Adds a collection of packages to be scanned for model types.
      Parameters:
      packages - The packages to add.

    • createKnowledge

      public void createKnowledge() throws Exception
      Creates the knowledge base by discovering types, building hierarchies, and gathering usage information.
      Throws:
      Exception - if an error occurs during creation.

    • createKnowledge

      public void createKnowledge(Collection<ClasspathModelKnowledge> modelKnowledges) throws Exception
      Creates the knowledge base by merging the classes already discovered by other, previously created ClasspathModelKnowledge instances, avoiding a redundant rescan of their packages.
      Parameters:
      modelKnowledges - The already-created model knowledges to merge.
      Throws:
      Exception - if an error occurs during creation.

    • getClassesDag

      public Dag<Class<Element>> getClassesDag(AccessType accessType)
      Returns the class hierarchy DAG for a specific access type.
      Parameters:
      accessType - The access type.
      Returns:
      The Dag of classes.

    • getDiscovery

      public Discovery<Element> getDiscovery(AccessType accessType)
      Returns the discovery instance for a specific access type.
      Parameters:
      accessType - The access type.
      Returns:
      The Discovery instance.
