Constructor Detail

TemplateLoader

public TemplateLoader()

Creates a TemplateLoader that uses the current ClassLoader as a base. It is recommended that templates be compiled to a base package and that a TemplateLoader be constructed with the package prefix. This way, the TemplateLoader can easily distinguish between template classes and normal classes, only loading the templates.

TemplateLoader

public TemplateLoader(java.lang.String packagePrefix)

Creates a TemplateLoader that uses the current ClassLoader as a base.

Parameters:

packagePrefix - Package that templates should be loaded from

TemplateLoader

public TemplateLoader(java.lang.ClassLoader baseLoader,
                      java.lang.String packagePrefix)

Creates a TemplateLoader that uses the given ClassLoader as a base. A base ClassLoader is used to load both template and non-template classes. The base ClassLoader can use the package prefix for determining whether or not it is loading a template.

Parameters:

baseLoader - Base ClassLoader

packagePrefix - Package that templates should be loaded from
