public class MetaTagAdjuster
extends ProxyReceiver

The MetaTagAdjuster adds a meta element to the content of the head element, indicating the required content type and encoding; it also removes any existing meta element containing this information

Constructor Detail

MetaTagAdjuster

public MetaTagAdjuster(Receiver next)

Create a new MetaTagAdjuster

Parameters:

next - the next receiver in the pipeline

Method Detail

setOutputProperties

public void setOutputProperties(Properties details)

Set output properties

Parameters:

details - the serialization properties

setIsXHTML

public void setIsXHTML(boolean xhtml)

Indicate whether we're handling HTML or XHTML

startElement

public void startElement(NodeName nameCode,
                         SchemaType typeCode,
                         Location location,
                         int properties)
                  throws XPathException

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

nameCode - integer code identifying the name of the element within the name pool.

typeCode - integer code identifying the element's type within the name pool.

location -

properties - properties of the element node

Throws:

XPathException - if an error occurs

attribute

public void attribute(NodeName nameCode,
                      SimpleType typeCode,
                      CharSequence value,
                      Location 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.

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

Parameters:

nameCode - The name of the attribute

typeCode - The type of the attribute

locationId - the location of the node in the source, or of the instruction that created it

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

Throws:

IllegalStateException: - attempt to output an attribute when there is no open element start tag

XPathException - if an error occurs

namespace

public void namespace(NamespaceBindingSet namespaceBindings,
                      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.

Specified by:

namespace in interface Receiver

Overrides:

namespace in class ProxyReceiver

Parameters:

namespaceBindings - the prefix/uri pair representing the namespace binding

properties - any special properties to be passed on this call

Throws:

IllegalStateException: - attempt to output a namespace when there is no open element start tag

XPathException - if an error occurs

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.

Specified by:

startContent in interface Receiver

Overrides:

startContent in class ProxyReceiver

Throws:

XPathException - if an error occurs

endElement

public void endElement()
                throws XPathException

End of element

Specified by:

endElement in interface Receiver

Overrides:

endElement in class ProxyReceiver

Throws:

XPathException - if an error occurs
