Class ComplexContentOutputter

All Implemented Interfaces:

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.

Overrides:

XPathException - if an error occurs

startDocument

public void startDocument(int properties)
                   throws XPathException

Start of a document node.

Parameters:

properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOptions

endDocument

public void endDocument()
                 throws XPathException

Notify the end of a document node

Throws:

XPathException - if an error occurs

characters

public void characters(CharSequence s,
              Location 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 -

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 - for any failure

startElement

public void startElement(NodeName elemName,
                SchemaType typeCode,
                Location location,
                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:

elemName - The element name

location -

typeCode - the type annotation of the element.

properties - bit-significant properties of the element node. If there are no revelant properties, zero is supplied. The definitions of the bits are in class ReceiverOptions

Throws:

XPathException - if an error occurs

namespace

public void namespace(NamespaceBinding nsBinding,
             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:

nsBinding - The namespace binding

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:

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(NodeName attName,
             SimpleType typeCode,
             CharSequence value,
             Location 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:

attName - The name of the attribute

value - The value of the attribute

locationId -

properties - Bit fields containing properties of the attribute to be written @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.

typeCode - The type annotation of the attribute

Throws:

XPathException - if an error occurs

public void endElement()
                throws XPathException

Output an element end tag.

Throws:

Specified by:

append in class SequenceReceiver

Parameters:

item - the item to be appended

usesTypeAnnotations

public boolean usesTypeAnnotations()

Returns:

true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation
