Examples of org.apache.tapestry.NestedMarkupWriter

org.apache.tapestry.NestedMarkupWriter
A writer that is created by, and nested within, another markup writer. This is used by many components that need to render their bodies to fully determine how to write the markup before their bodies; the markup is stored inside the nested markup writer until needed. @author Howard M. Lewis Ship @since 4.0 @see org.apache.tapestry.IMarkupWriter#getNestedWriter()
