Examples of org.apache.tapestry.MarkupWriter

org.apache.tapestry.MarkupWriter
An interface used by objects, such as Tapestry components, that need to render themselves as some form of XML markup. A markup writer maintains the idea of a current element. Attributes are added to the current element, and new text and elements are placed inside the current element. In this way, the markup writer maintains a facade that XML markup is generated as a stream, even though the implementation builds a kind of DOM tree. The DOM tree can be also be manipulated. This solves a number of problems from Tapestry 4 (and earlier) where random access to the DOM was desired and had to be simulated through complex buffering.
