public abstract class AttributeValidator
extends ContentValidator

This class is an abstract superclass for all the receivers that do element content validation. Since all kinds of element content can be associated with attributes, the attribute validation is handled at this level.

Method Detail

setAttributeGroup

public void setAttributeGroup(AttributeGroupDecl attributeGroup)
                       throws ValidationException

Identify the set of attributes permitted by the complex type being validated. This is called during initialization of the AttributeValidator. It is not called if the type is a simple type; in such cases any attribute is an error, except for the xsi: attributes permitted on all elements.

Parameters:

attributeGroup - the set of attributes declared for this complex type

Throws:

ValidationException

attribute

public void attribute(int nameCode,
                      int typeCode,
                      CharSequence value,
                      int locationId,
                      int properties)
               throws XPathException

Handle an attribute

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

Parameters:

nameCode - integer identifying the name of the attribute

typeCode - integer identifying the type annotation (ignored)

value - the value of the attribute

properties - additional properties 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 - On any failure to write the attribute

startElement

public void startElement(int nameCode,
                         int typeCode,
                         int locationId,
                         int properties)
                  throws XPathException

Handle the start tag for a child element of the element being validated

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ContentValidator

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.

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 - properties of the element node

Throws:

XPathException

startContent

public final void startContent()
                        throws XPathException

Notify the start of the content, that is, the completion of all attributes and namespaces. The ValidationStack class is responsible for detecting this event and calling this method. 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

characters

public void characters(CharSequence chars,
                       int locationId,
                       int properties)
                throws XPathException

Handle character data appearing as a child of the element being validated

Specified by:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

Parameters:

chars - The character content

properties - Additional properties

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 this element does not allow character data
