Class UncommittedSerializer

java.lang.Object
net.sf.saxon.event.SequenceReceiver
net.sf.saxon.event.ProxyReceiver
net.sf.saxon.serialize.UncommittedSerializer
All Implemented Interfaces:
Result, Receiver
public class UncommittedSerializer extends ProxyReceiver
This class is used when the decision on which serialization method to use has to be delayed until the first element is read. It buffers comments and processing instructions until that happens; then when the first element arrives it creates a real serialization pipeline and uses that for future output.

    • startElement

      public void startElement(NodeName elemName, SchemaType type, AttributeMap attributes, NamespaceMap namespaces, Location location, int properties) throws XPathException
      Output an element start tag.
      This can only be called once: it switches to a substitute output generator for XML, XHTML, or HTML, depending on the element name.

      startElement in interface Receiver
      Overrides:
      startElement in class ProxyReceiver
      Parameters:
      elemName - the name of the element.
      type - the type annotation of the element.
      attributes - the attributes of this element
      namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements
      location - an object providing information about the module, line, and column where the node originated
      properties - bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in class ReceiverOption
      Throws:
      XPathException - if an error occurs

    • startDocument

      public void startDocument(int properties) throws XPathException
      Description copied from class: ProxyReceiver

      Parameters:
      properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOption
      Throws:
      XPathException - if an error occurs
