Examples of org.apache.tapestry.runtime.Component

org.apache.tapestry.runtime.Component
Interface that defines the lifecycle of a component, within a page, allowing for callbacks into the component for many different events. This interface is part of the public API for Tapestry, but is not expected to be directly implemented by component classes; it should only be implemented as part of the component class transformation process.
Most of the methods are related to render phases; see the corresponding annotations and component rendering documentation to see how they relate to each other.
This interface is likely to change without notice.
