      • visit

        public boolean visit​(DependencyNode node)
        Starts the visit to the specified dependency node.
        Specified by:

        Parameters:
        node - the dependency node to visit
        Returns:
        true to visit the specified dependency node's children, false to skip the specified dependency node's children and proceed to its next sibling
      • endVisit

        public boolean endVisit​(DependencyNode node)
        Ends the visit to to the specified dependency node.
        Specified by:
        endVisit in interface DependencyNodeVisitor
        Parameters:
        node - the dependency node to visit
        Returns:
        true to visit the specified dependency node's next sibling, false to skip the specified dependency node's next siblings and proceed to its parent
      • getDependencyNodeVisitor

        public DependencyNodeVisitor getDependencyNodeVisitor()
        Gets the dependency node visitor that this visitor applies on the resultant dependency tree.
        Returns:
        the dependency node visitor, or null for none
      • getDependencyTree

        public DependencyNode getDependencyTree()
        Gets the root node of the resultant dependency tree constructed by this visitor.
        Returns:
