Package facets.util.datatree Description

Simple XML-compatible trees.

datatree provides a Java API for tree-structured data that is both largely compatible with XML and straightforward to use. datatree nodes can be

• constructed directly without the need for a factory, complete with their data values and child nodes
• modified, manipulated and queried using standard Java idioms
• represented as and constructed from XML
• easily rendered and edited in simple tree viewers

The API itself is defined in this package, while facets.util provides supporting API and facets.util.app a demonstration class.

All three packages are extracted from the Facets implementation of Superficial http://superficial.sourceforge.net.
