Examples of org.geotools.xml.transform.TransformerBase

org.geotools.xml.transform.TransformerBase
TransformerBase provides support for writing Object->XML encoders. The basic pattern for useage is to extend TransformerBase and implement the createTranslator(ContentHandler) method. This is easiest done by extending the inner class TranslatorSupport. A Translator uses a ContentHandler to issue SAX events to a javax.xml.transform.Transformer. If possible, make the translator public so it can be used by others as well. @author Ian Schneider @source $URL$
