Examples of IComponentSpecification

org.apache.tapestry.spec.IComponentSpecification
A specification for a component, as read from an XML specification file.
A specification consists of
- An implementing class
- An optional template
- An optional description
- A set of contained components
- Bindings for the properties of each contained component
- A set of named assets
- Definitions for helper beans
- Any reserved names (used for HTML attributes)
From this information, an actual component may be instantiated and initialized. Instantiating a component is usually a recursive process, since to initialize a container component, it is necessary to instantiate and initialize its contained components as well. @see org.apache.tapestry.IComponent @see IContainedComponent @see IComponentSpecification @see org.apache.tapestry.engine.IPageLoader @author glongman@intelligentworks.com @version $Id: IComponentSpecification.java 243791 2004-02-19 17:38:13Z hlship $
