[Java] Class BaseTemplate

  • All Implemented Interfaces and Traits:
    Writable

    public abstract class BaseTemplate
    extends Object
    implements Writable 

    All templates compiled through MarkupTemplateEngine extend this abstract class, which provides a number of utility methods to generate markup. An instance of this class can be obtained after calling Template.make or Template.make)} on a template generated by MarkupTemplateEngine.createTemplate.

    It is advised to use a distinct template instance for each thread (or more simply, each rendered document) for thread safety and avoiding mixing models.

    For the application needs, it is possible to provide more helper methods by extending this class and configuring the base template class using the TemplateConfiguration.setBaseTemplateClass method.

    • Method Detail

      • public BaseTemplate comment(Object cs)

        Renders the supplied object using its Object.toString method inside a comment markup block (<!-- ... -->). The object is rendered as is, unescaped.

        throws:
        IOException
        Parameters:
        cs - the object to be rendered inside an XML comment block.
        Returns:
        this template instance.

      • public Closure contents(Closure cl)

        Wraps a closure so that it can be used as a prototype for inclusion in layouts. This is useful when you want to use a closure in a model, but that you don't want to render the result of the closure but instead call it as if it was a specification of a template fragment.

        Parameters:
        cl - the fragment to be wrapped
        Returns:
        a wrapped closure returning an empty string

      • public Object fragment(Map model, String templateText)

        Renders an embedded template as a fragment. Fragments are cached in a template, meaning that if you use the same fragment in a template, it will only be compiled once, but once per template instance. This is less performant than using layout(java.util.Map, String).

        throws:
        IOException
        throws:
        ClassNotFoundException
        Parameters:
        model - model to be passed to the template
        templateText - template body
        Returns:
        this template instance

      • public Map getModel()

      • public Writer getOut()

        Convenience method to return the current writer instance.

        Returns:
        the current writer

      • public void includeEscaped(String templatePath)

        Includes contents of another file, not as a template but as escaped text.

        throws:
        IOException
        Parameters:
        templatePath - the path to the other file

      • public void includeGroovy(String templatePath)

        Includes another template inside this template.

        throws:
        IOException
        throws:
        ClassNotFoundException
        Parameters:
        templatePath - the path to the included resource.

      • public void includeUnescaped(String templatePath)

        Includes contents of another file, not as a template but as unescaped text.

        throws:
        IOException
        Parameters:
        templatePath - the path to the other file

      • public Object layout(Map model, String templateName)

        Imports a template and renders it using the specified model, allowing fine-grained composition of templates and layouting. This works similarly to a template include but allows a distinct model to be used. This version doesn't inherit the model from the parent. If you need model inheritance, see layout(java.util.Map, String, boolean).

        throws:
        IOException
        throws:
        ClassNotFoundException
        Parameters:
        model - model to be passed to the template
        templateName - the name of the template to be used as a layout
        Returns:
        this template instance

      • public Object layout(Map model, String templateName, boolean inheritModel)

        Imports a template and renders it using the specified model, allowing fine-grained composition of templates and layouting. This works similarly to a template include but allows a distinct model to be used. If the layout inherits from the parent model, a new model is created, with the values from the parent model, eventually overridden with those provided specifically for this layout.

        throws:
        IOException
        throws:
        ClassNotFoundException
        Parameters:
        model - model to be passed to the template
        templateName - the name of the template to be used as a layout
        inheritModel - a boolean indicating if we should inherit the parent model
        Returns:
        this template instance

      • public Object methodMissing(String tagName, Object args)

        This is the main method responsible for writing a tag and its attributes. The arguments may be:

        • a closure
        • in which case the closure is rendered inside the tag body
        • a string
        • , in which case the string is rendered as the tag body
        • a map of attributes
        • in which case the attributes are rendered inside the opening tag

        or a combination of (attributes,string), (attributes,closure)

        throws:
        IOException
        Parameters:
        tagName - the name of the tag
        args - tag generation arguments
        Returns:
        this template instance

      • public BaseTemplate pi(Map<?, ?> attrs)

        Renders processing instructions. The supplied map contains all elements to be rendered as processing instructions. The key is the name of the element, the value is either a map of attributes, or an object to be rendered directly. For example:

        pi("xml-stylesheet":[href:"mystyle.css", type:"text/css"])

        will be rendered as:

         <?xml-stylesheet href='mystyle.css' type='text/css'?>
         
        throws:
        IOException
        Parameters:
        attrs - the attributes to render
        Returns:
        this template instance

      • public abstract Object run()

      • public Object tryEscape(Object contents)

        Escapes the string representation of the supplied object if it derives from CharSequence, otherwise returns the object itself.

        Parameters:
        contents - an object to be escaped for XML
        Returns:
        an escaped string, or the object itself

      • @Override
        public Writer writeTo(Writer out)

        Main method used to render a template.

        throws:
        IOException
        Parameters:
        out - the Writer to which this Writable should output its data.
        Returns:
        a writer instance

      • public BaseTemplate xmlDeclaration()

        Renders an XML declaration header. If the declaration encoding is set in the template configuration, then the encoding is rendered into the declaration.

        throws:
        IOException
        Returns:
        this template instance

      • public BaseTemplate yield(Object obj)

        Renders the object provided as parameter using its Object.toString method, The contents is rendered after being escaped for XML, enforcing valid XML output.

        throws:
        IOException
        Parameters:
        obj - the object to be rendered
        Returns:
        this template instance

      • public BaseTemplate yieldUnescaped(Object obj)

        Renders the object provided as parameter using its Object.toString method, The contents is rendered as is, unescaped. This means that depending on what the Object.toString method call returns, you might create invalid markup.

        throws:
        IOException
        Parameters:
        obj - the object to be rendered unescaped
        Returns:
