All Implemented Interfaces:

Result, Receiver

public class EntityValidator
extends ProxyReceiver

This class validates that elements and attributes of type ENTITY or ENTITIES have values are declared in the DOCTYPE declaration of the instance document as unparsed entities.

This component of the validation pipeline is used during standalone schema validation, but not during validation invoked from XSLT or XQuery, as constructed trees never contain unparsed entities.

Constructor Detail

EntityValidator

public EntityValidator(Receiver next)

Create a validator for attributes of type ENTITY or ENTITIES

Parameters:

next - the next receiver in the pipeline

Method Detail

setUnparsedEntity

public void setUnparsedEntity(String name,
                     String uri,
                     String publicId)
                       throws XPathException

Set the URI for an unparsed entity in the document.

Specified by:

setUnparsedEntity in interface Receiver

Overrides:

setUnparsedEntity in class ProxyReceiver

Parameters:

name - The name of the unparsed entity

uri - The system identifier of the unparsed entity

publicId - The public identifier of the unparsed entity

Throws:

XPathException - if an error occurs

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

characters

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

Character data

Specified by:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

Parameters:

chars - The characters

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 - 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 - 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

attribute

public void attribute(NodeName nameCode,
             SimpleType 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

usesTypeAnnotations

public boolean usesTypeAnnotations()

Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events

Specified by:

usesTypeAnnotations in interface Receiver

Overrides:

usesTypeAnnotations in class ProxyReceiver

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

reportValidationError

protected void reportValidationError(ValidationException err,
                         int locationId)
                              throws ValidationException

Report a validation error

Parameters:

err - The validation exception

locationId - identifies the location in the source document or stylesheet/query where the validation error was detected

Throws:

ValidationException - if the error is considered fatal
