public class ValidationStack
extends ValidatingFilter

This class manages the receivers that do element content validation. It maintains a stack of Validators, each of which does local element validation of the contents of a single element, adding a new validator to the stack to handle each layer of nesting.

Constructor Details

ValidationStack

public ValidationStack(Receiver next,
 int initialValidationMode,
 SchemaType initialType)

Create a validation stack

Parameters:

next - the destination of events after passing through validation

initialValidationMode - the initial validation mode, strict/lax

initialType - the initial type to validate against, if any

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

setTopLevelElement

public void setTopLevelElement(NodeName name)

Set the name of the required top-level element (if any)

Parameters:

name - the name of the element that must appear at the root of the subtree being validated

getTopLevelElement

public NodeName getTopLevelElement()

Get the name of the required top-level element (if any)

Returns:

the name of the element that must appear at the root of the subtree being validated, or null if none has been set

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

setIsNilled

public void setIsNilled(boolean nilled)

Indicate whether the current element is nilled

Parameters:

nilled - true if xsi:nil is set

setXsiValidationErrors

public void setXsiValidationErrors(List<ValidationFailure> errors)

Supply a list of errors found in attributes in the XSI namespace. This is called immediately before calling startElement on the element containing these erroneous attributes

Parameters:

errors - the list of errors

startElement

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

Process element start tag

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

elemName - the name of the element.

typeCode - 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

setInitialValidator

public void setInitialValidator(ContentValidator validator)

Set the initial validator to be used for the outermost element

Parameters:

validator - the validator to be used for the outermost element being validated

characters

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

Description copied from class: ProxyReceiver

Character data

Specified by:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

Parameters:

chars - The characters

locationId - provides information such as line number and system ID.

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

endDocument

public void endDocument()
                 throws XPathException

Notify the end of a document node

Specified by:

endDocument in interface Receiver

Overrides:

endDocument in class ProxyReceiver

Throws:

XPathException - if an error occurs

setKeepStatistics

public void setKeepStatistics(boolean keep)

Ask that statistics be maintained for the duration of the validation episode. The statistics indicate how often particular schema components (currently, element declarations and types) have been used.

Parameters:

keep - true if statistics are to be kept, false if not

getCoverageStatistics

public Map<SchemaComponent,Integer> getCoverageStatistics()

Get the statistics showing the usage of individual schema components during a validation episode

Returns:

a table showing for each component that has been used, the number of times it has been used. If statistics are not being maintained, returns null.
