Class ComplexContentOutputter

  • All Implemented Interfaces:
    javax.xml.transform.Result, Receiver

    public final class ComplexContentOutputter
    extends SequenceReceiver
    This class is used for generating complex content, that is, the content of an element or document node. It enforces the rules on the order of events within complex content (attributes and namespaces must come first), and it implements part of the namespace fixup rules, in particular, it ensures that there is a namespace node for the namespace used in the element name and in each attribute name.

    The same ComplexContentOutputter may be used for generating an entire XML document; it is not necessary to create a new outputter for each element node.

      • characters

        public void characters​(java.lang.CharSequence s,
                               int locationId,
                               int properties)
                        throws XPathException
        Produce text content output.
        Special characters are escaped using XML/HTML conventions if the output format requires it.
        Parameters:
        s - The String to be output
        locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
        properties - Bit significant value. The following bits are defined:
        DISABLE_ESCAPING
        Disable escaping for this text node
        USE_CDATA
        Output as a CDATA section
        NO_SPECIAL_CHARACTERS
        Value contains no special characters
        WHITESPACE
        Text is all whitespace
        Throws:
        XPathException - for any failure
      • startElement

        public void startElement​(int nameCode,
                                 int typeCode,
                                 int locationId,
                                 int properties)
                          throws XPathException
        Output an element start tag.
        The actual output of the tag is deferred until all attributes have been output using attribute().
        Parameters:
        nameCode - The element name code
        typeCode - integer code identifying the element's type within the name pool. The value -1 indicates the default type, xdt:untyped.
        locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
        properties - bit-significant properties of the element node. If there are no revelant properties, zero is supplied.
        Throws:
        XPathException
      • namespace

        public void namespace​(int nscode,
                              int properties)
                       throws XPathException
        Output a namespace declaration.
        This is added to a list of pending namespaces for the current start tag. If there is already another declaration of the same prefix, this one is ignored, unless the REJECT_DUPLICATES flag is set, in which case this is an error. Note that unlike SAX2 startPrefixMapping(), this call is made AFTER writing the start tag.
        Parameters:
        nscode - The namespace code
        properties - The most important property is REJECT_DUPLICATES. If this property is 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: it sets the REJECT_DUPLICATES flag, and this is treated as a hard error.
        Throws:
        XPathException - if there is no start tag to write to (created using writeStartTag), or if character content has been written since the start tag was written.
      • attribute

        public void attribute​(int nameCode,
                              int typeCode,
                              java.lang.CharSequence value,
                              int locationId,
                              int properties)
                       throws XPathException
        Output an attribute value.
        This is added to a list of pending attributes for the current start tag, overwriting any previous attribute with the same name.
        This method should NOT be used to output namespace declarations.
        Parameters:
        nameCode - The name of the attribute
        value - The value of the attribute
        properties - Bit fields containing properties of the attribute to be written
        typeCode - The type of the attribute, as held in the name pool. The additional bit NodeInfo.IS_DTD_TYPE may be set to indicate a DTD-derived type.
        locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
        Throws:
        XPathException - if there is no start tag to write to (created using writeStartTag), or if character content has been written since the start tag was written.
