Class SequenceWrapper

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

    public class SequenceWrapper
    extends SequenceReceiver
    This class can be used in a push pipeline: it accepts any sequence as input, and generates a document in which the items of the sequence are wrapped by elements containing information about the types of the items in the input sequence.

      • attribute

        public void attribute​(int nameCode,
                              int typeCode,
                              java.lang.CharSequence value,
                              int locationId,
                              int properties)
                       throws XPathException
        Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.
        Parameters:
        nameCode - The name of the attribute, as held in the name pool
        typeCode - The type of the attribute, as held in the name pool
        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
        value - the string value of the attribute
        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
      • namespace

        public void namespace​(int namespaceCode,
                              int properties)
                       throws XPathException
        Notify a namespace. Namespaces are notified after the startElement event, and before any children for the element. The namespaces that are reported are only required to include those that are different from the parent element; however, duplicates may be reported. A namespace must not conflict with any namespaces already used for element or attribute names.
        Parameters:
        namespaceCode - an integer: the top half is a prefix code, the bottom half a URI code. These may be translated into an actual prefix and URI using the name pool. A prefix code of zero represents the empty prefix (that is, the default namespace). A URI code of zero represents a URI of "", that is, a namespace undeclaration.
        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
      • characters

        public void characters​(java.lang.CharSequence chars,
                               int locationId,
                               int properties)
                        throws XPathException
        Character data
        Parameters:
        chars - The characters
        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
        Throws:
        XPathException
      • comment

        public void comment​(java.lang.CharSequence chars,
                            int locationId,

                     throws XPathException
        Output a comment
        Parameters:
        chars - The content of the comment
        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 - Additional information about the comment. The following bits are defined:
        CHECKED
        Comment is known to be legal (e.g. doesn't contain "--")
        Throws:
        XPathException
      • processingInstruction

        public void processingInstruction​(java.lang.String target,
                                          java.lang.CharSequence data,
                                          int locationId,
                                          int properties)
                                   throws XPathException
        Processing Instruction
        Parameters:
        target - The PI name. This must be a legal name (it will not be checked).
        data - The data portion of the processing instruction
        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 - Additional information about the PI. The following bits are defined:
        CHECKED
        Data is known to be legal (e.g. doesn't contain "?>")
        Throws:
        XPathException
      • startContent

        public void startContent()
                          throws XPathException
        Notify the start of the content, that is, the completion of all attributes and namespaces. Note that the initial receiver 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.
        Throws:
        XPathException
