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 Detail

XSIAttributeHandler

public XSIAttributeHandler(ValidationStack out)

Create a handler for xsi: attributes

Parameters:

out - the next filter in the pipeline

Method Detail

setStartTagBuffer

public void setStartTagBuffer(StartTagBufferEE stb)

Provide the location of the start tag buffer which buffers the attributes for a start tag and resolves namespaces

Parameters:

stb - the start tag buffer

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 nameCode,
                         SchemaType typeCode,
                         int locationId,
                         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.

properties - for future use. Should be set to zero.

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 an error occurs

attribute

public void attribute(NodeName nameCode,
                      SimpleType typeCode,
                      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.

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

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:

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

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
