Examples of org.apache.tapestry.Block

org.apache.tapestry.Block
A block is a collection of static text and elements, and components, derived from a component template. In the template, a block is demarcated using the <t:block> or <t:parameter> elements. The interface defines no methods, but the provided implementations of Block are capable of rendering their contents on demand.
