Class AbstractDelegatingTemplateLoader

java.lang.Object
  info.magnolia.freemarker.loaders.AbstractDelegatingTemplateLoader

All Implemented Interfaces:

freemarker.cache.TemplateLoader

Direct Known Subclasses:

LazyFileTemplateLoader, LazyWebappTemplateLoader

public abstract class AbstractDelegatingTemplateLoader
extends java.lang.Object
implements freemarker.cache.TemplateLoader

An abstract TemplateLoader that will attempt to initialize its delegate TemplateLoader and use a null object implementation until it succeeds. This allows us to wrap existing, constructor-configured TemplateLoader implementations, into content2bean-able beans, thus making them configurable in Magnolia's config repository.
