Package edu.cornell.mannlib.vitro.webapp.controller.freemarker

Class DelimitingTemplateLoader

java.lang.Object

edu.cornell.mannlib.vitro.webapp.controller.freemarker.DelimitingTemplateLoader

All Implemented Interfaces:

freemarker.cache.TemplateLoader

public class DelimitingTemplateLoader
extends Object
implements freemarker.cache.TemplateLoader

Wrap a TemplateLoader, so each time a template is read, delimiters will be inserted at the beginning and end. This makes it easier for a developer can see what lines of HTML come from which templates. TemplateLoader returns a token object when finding a template, and then recognizes that object when it is used as an argument to getLastModified() or getReader(). In order to keep track of the template name, we wrap the token object and the name in a token of our own. Taking the easy way out and reading in the entire template into a string. This limits the template size to less than 2^31 characters (~2 GBytes). That seems adequate.
