All Implemented Interfaces:

Result, Receiver

public class XSIAttributeHandler
extends ValidatingFilter

This class processes attributes such as xsi:schemaLocation and xsi:type. To achieve this, it needs to be preceded in the pipeline by a StartTagBuffer, which buffers all attributes and namespaces, because the xsi:type and schemaLocation need to be processed before the start element event. Apart from the StartTagBuffer, this is the first class in the validation pipeline.

The main work of this class can be done in the startElement event, because the StartTagBuffer ensures that by this time, all the namespaces and attributes for the element are known and accessible.

Constructor Details

XSIAttributeHandler

public XSIAttributeHandler(ValidationStack out)

Create a handler for xsi: attributes

Parameters:

out - the next filter in the pipeline

Method Details

setPipelineConfiguration

public void setPipelineConfiguration(PipelineConfiguration pipe)

Description copied from interface: Receiver

Set the pipeline configuration

Specified by:

setPipelineConfiguration in interface Receiver

Overrides:

setPipelineConfiguration in class ProxyReceiver

Parameters:

pipe - the pipeline configuration

startElement

public void startElement(NodeName elemName,
 SchemaType type,
 AttributeMap attributes,
 NamespaceMap namespaces,
 Location location,
 int properties)
                  throws XPathException

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

elemName - the name of the element.

type - the type annotation of the element.

attributes - the attributes of this element

namespaces - the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elements

location - an object providing information about the module, line, and column where the node originated

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

Throws:

XPathException - if an error occurs

endDocument

public void endDocument()
                 throws XPathException

Description copied from class: ProxyReceiver

Notify the end of a document node

Specified by:

endDocument in interface Receiver

Overrides:

endDocument in class ProxyReceiver

Throws:

XPathException - if an error occurs
