Examples of org.pegdown.ast.Node

org.pegdown.ast.Node
Base class of all AST nodes classes. Provides the basic infrastructure and can be used directly as a simple intermediate AST node without any special functionality (i.e. as a basic parent node).

            RootNode rootNode = PEGDOWN_PROCESSOR.parseMarkdown( text.toCharArray() );
            if ( !haveTitle && rootNode.getChildren().size() > 0 )
            {
                // use the first (non-comment) node only if it is a heading
                int i = 0;
                Node firstNode = null;
                while ( i < rootNode.getChildren().size() && isHtmlComment(
                    ( firstNode = rootNode.getChildren().get( i ) ) ) )
                {
                    i++;
                }
