Class NormalizeNewlines

  • All Implemented Interfaces:
    TemplateModel, TemplateTransformModel

    public class NormalizeNewlines
    extends Object
    implements TemplateTransformModel

    Transformer that supports FreeMarker legacy behavior: all newlines appearing within the transformed area will be transformed into the platform's default newline. Unlike the old behavior, however, newlines generated by the data model are also converted. Legacy behavior was to leave newlines in the data model unaltered.

    Usage:
    From java:

     SimpleHash root = new SimpleHash();
    
     root.put( "normalizeNewlines", new freemarker.template.utility.NormalizeNewlines() );
    
     ...
     

    From your FreeMarker template:

     <transform normalizeNewlines>
       <html>
       <head>
       ...
       <p>This template has all newlines normalized to the current platform's
       default.</p>
       ...
       </body>
       </html>
     </transform>

      • getWriter

        public Writer getWriter​(Writer out,
                                Map args)
        Description copied from interface: TemplateTransformModel
        Returns a writer that will be used by the engine to feed the transformation input to the transform. Each call to this method must return a new instance of the writer so that the transformation is thread-safe.
        Specified by:
        getWriter in interface TemplateTransformModel
        Parameters:
        out - the character stream to which to write the transformed output
        args - the arguments (if any) passed to the transformation as a map of key/value pairs where the keys are strings and the arguments are TemplateModel instances. This is never null. If you need to convert the template models to POJOs, you can use the utility methods in the DeepUnwrap class.
        Returns:
        a writer to which the engine will feed the transformation input, or null if the transform does not support nested content (body). The returned writer can implement the TransformControl interface if it needs advanced control over the evaluation of the transformation body.
      • transform

        public void transform​(Reader in,
                              Writer out)
                       throws IOException
        Performs newline normalization on FreeMarker output.
        Parameters:
        in - the input to be transformed
        out - the destination of the transformation
        Throws:
        IOException
