      • attribute

        public void attribute​(NodeName name,
                              SimpleType type,
                              java.lang.CharSequence value,

                              int properties)
        Description copied from class: ProxyOutputter
        Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.
        Overrides:
        attribute in class ProxyOutputter
        Parameters:
        name - The name of the attribute
        type - The type annotation of the attribute
        value - the string value of the attribute
        location - provides information such as line number and system ID.
        properties - Bit significant value. The following bits are defined:
        DISABLE_ESCAPING
        Disable escaping for this attribute
        NO_SPECIAL_CHARACTERS
        Attribute value contains no special characters
      • namespace

        public void namespace​(java.lang.String prefix,
                              java.lang.String uri,
                              int properties)
        Description copied from class: ProxyOutputter
        Notify a namespace binding. This method is called at some point after startElement(). The semantics are similar to the xsl:namespace instruction in XSLT, or the namespace node constructor in XQuery. A namespace must not conflict with any namespaces already used for element or attribute names.
        Overrides:
        namespace in class ProxyOutputter
        Parameters:
        prefix - The namespace prefix; zero-length string for the default namespace
        uri - The namespace URI. In some cases a zero-length string may be used to indicate a namespace undeclaration.
        properties - The REJECT_DUPLICATES property: if set, the namespace declaration will be rejected if it conflicts with a previous declaration of the same prefix. If the property is not set, the namespace declaration will be ignored if it conflicts with a previous declaration. This reflects the fact that when copying a tree, namespaces for child elements are emitted before the namespaces of their parent element. Unfortunately this conflicts with the XSLT rule for complex content construction, where the recovery action in the event of conflicts is to take the namespace that comes last. XSLT therefore doesn't recover from this error:
      • startContent

        public void startContent()
        Description copied from class: ProxyOutputter
        Notify the start of the content, that is, the completion of all attributes and namespaces. Note that the initial Outputter of output from XSLT instructions will not receive this event, it has to detect it itself. Note that this event is reported for every element even if it has no attributes, no namespaces, and no content.
        Overrides:
        startContent in class ProxyOutputter
      • characters

        public void characters​(java.lang.CharSequence chars,
                               Location location,
                               int properties)
        Description copied from class: ProxyOutputter
        Notify character data. Note that some receivers may require the character data to be sent in a single event, but in general this is not a requirement.
        Specified by:
        characters in interface Receiver
        Overrides:
        characters in class ProxyOutputter
        Parameters:
        chars - The characters
        location - provides information such as line number and system ID.
        properties - Bit significant value. The following bits are defined:
        DISABLE_ESCAPING
        Disable escaping for this text node
        USE_CDATA
        Output as a CDATA section
      • processingInstruction

                                          Location location,
                                          int properties)

      • setHasFailed

        public void setHasFailed()
        Mark this feed as having failed (that is, as having detected and reported a dynamic error). Once the feed is marked as having failed, it should not attempt to process any further input.
