Examples of org.exist.storage.serializers.Serializer

org.exist.storage.serializers.Serializer
Serializer base class, used to serialize a document or document fragment back to XML. A serializer may be obtained by calling DBBroker.getSerializer(). The class basically offers two overloaded methods: serialize() and toSAX(). serialize() returns the XML as a string, while toSAX() generates a stream of SAX events. The stream of SAX events is passed to the ContentHandler set by setContentHandler(). Internally, both types of methods pass events to a {@link org.exist.util.serializer.Receiver}. Subclasses thus have to implement the various serializeToReceiver() methods. Output can be configured through properties. Property keys are defined in classes {@link javax.xml.transform.OutputKeys} and {@link org.exist.storage.serializers.EXistOutputKeys} @author Wolfgang Meier
