public class JDOMetaDataParser

extends com.solarmetric.modules.tools.compiler.CFMetaDataParser

Custom SAX parser used by the system to quickly parse JDO metadata files.

This parser maintains a static cache and will never parse the same source more than once; if it is called with a class or source that has already been parsed, it will return an empty list. This is for general efficiency (otherwise types without metadata will require continuous reparsing of the [package-name].jdo for their package and system.jdo, if they exist), and has the added upside of preventing infinite recursion in scenarious where types in the same [package-name].jdo refer to each other or to non-persistent types in that package.
