|
28 | * Utility service, <code>tapestry.page.ComponentTemplateLoader</code>, which will process the |
|
29 | * component's {@link org.apache.tapestry.parse.ComponentTemplate template}, which involves working |
|
30 | * through the nested structure of the template and hooking the various static template blocks and |
|
31 | * components together using {@link org.apache.tapestry.IComponent#addBody(IRender)}and |
|
32 | * {@link org.apache.tapestry.ITemplateComponent#addOuter(IRender)}. |
|
33 | * <p> |
|
34 | * Because this service must be reentrant, it acts as a factory for a |
|
35 | * {@link org.apache.tapestry.services.impl.ComponentTemplateLoaderLogic}that is created (and |
|
36 | * discarded) for each component whose template is loaded. |
