JDocumentRenderer is an abstract class which provides a number of methods and properties to assist in rendering a particular document type. Not all document types implement renderers in this way. Some of the methods listed will be overridden by the child class so you should check the child class documentation for further information.
|render||Renders a script and returns the results as a string|
|getContentType||Return the content type of the renderer|
