Class AntlrMill

java.lang.Object
de.monticore.grammar.concepts.antlr.antlr.AntlrMill
Direct Known Subclasses:
AntlrMillForGrammar_WithConcepts
public class AntlrMill extends Object
The mill is a factory for builders and other commonly used functions, such as parsers or visitors. The mill was introduced to ensure compositionality of languages, while retaining reusability of functions developed for sublanguages. Only one mill instance exists, even though in composed languages it is available under several static signatures.

  • Method Details

    • getMill

      public static AntlrMill getMill()

    • init

      public static void init()
      Initializes a languages Mill. This will also initialize the Mills of all languages it depends on. This ensures that all objects of this mill, such as builders, traversers, scopes, ..., deliver the element of the correct language.

    • prettyPrint

      public static String prettyPrint(de.monticore.ast.ASTNode node, boolean printComments)
      Uses the composed pretty printer to print an ASTNode of this language
      Parameters:
      node - The ASTNode to be printed
      printComments - Whether comments should be printed
      Returns:
      The pretty printer output

    • _prettyPrint

      protected String _prettyPrint(de.monticore.ast.ASTNode node, boolean printComments)

    • typeDispatcher

      public static IAntlrTypeDispatcher typeDispatcher()

    • _typeDispatcher

      protected IAntlrTypeDispatcher _typeDispatcher()

    • traverser

      public static AntlrTraverser traverser()
      A traverser is the conceptual entry point for every action within the visitor infrastructure. Visitors may be added, which contain the implementations for the visit and endVisit methods. Handlers may be added to modify the default traversal strategy. Each traverser retains their traversed elements to avoid duplicate traversal, possibly requiring ITraverser.clearTraversedElements() to be called in case of re-use inheritanceTraverser() should be preferred over normal traverser, as they further enable language composition.
      Returns:
      a new instance of this language's traverser

    • _traverser

      protected AntlrTraverser _traverser()

    • inheritanceTraverser

      public static AntlrTraverser inheritanceTraverser()
      A traverser is the conceptual entry point for every action within the visitor infrastructure. Visitors may be added, which contain the implementations for the visit and endVisit methods. Handlers may be added to modify the default traversal strategy. Each traverser retains their traversed elements to avoid duplicate traversal, possibly requiring ITraverser.clearTraversedElements() to be called in case of re-use Inheritance Traverser should be preferred over default ones, as they further enable language composition.
      Returns:
      a new instance of this language's inheritance traverser

    • _inheritanceTraverser

      protected AntlrTraverser _inheritanceTraverser()

    • globalScope

      public static IAntlrGlobalScope globalScope()

    • _globalScope

    • _scope

      protected IAntlrScope _scope()

    • scopesGenitor

      public static AntlrScopesGenitor scopesGenitor()
      Returns a new ScopeGenitor. ScopeGenitors are responsible for creating the scope structure of artifacts of only this language and linking it with the AST nodes. Note: ScopeGenitors do NOT delegate to elements of composed languages which is why you are most likely looking for scopesGenitorDelegator().
      Returns:
      a new instance of this language's scope genitor

    • _scopesGenitor

      protected AntlrScopesGenitor _scopesGenitor()

    • scopesGenitorDelegator

      public static AntlrScopesGenitorDelegator scopesGenitorDelegator()
      Returns a new ScopeGenitorDelegator. Delegates to the ScopeGenitors of composed languages, used for instantiating symbol tables in the context of language composition See the delegators #createFromAST method.
      Returns:
      a new instance of this language's scope genitor delegator

    • _scopesGenitorDelegator
