GroovyPagesTemplateEngine (Grails 2.5.6.BUILD-SNAPSHOT)

org.codehaus.groovy.grails.web.pages.GroovyPagesTemplateEngine

All Implemented Interfaces and Traits:

org.springframework.context.ApplicationContextAware, org.springframework.web.context.ServletContextAware, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationListener, org.springframework.beans.factory.BeanClassLoaderAware
```
public class GroovyPagesTemplateEngine
extends ResourceAwareTemplateEngine
```
Based on (but not extending) the existing TemplateEngine implementations within Groovy. It allows GSP pages to be re-used in different context using code like the below: Template t = new GroovyPagesTemplateEngine() .createTemplate(context,request,response); t.make() .writeTo(out);
