public abstract class ContentValidator
extends ValidatingFilter

This class is an abstract superclass for all the validators. The class includes factory methods for constructing a validator.

Field Summary

static int	NIL_ALLOWED Constant indicating that xsi:nil is allowed and active.
static int	NIL_DISALLOWED Constant indicating that xsi:nil is disallowed.
static int	NIL_IGNORED Constant indicating that xsi:nil is allowed but ignored; this is true when we are validating against a type, rather than against an element declaration

Fields inherited from interface javax.xml.transform.Result

PI_DISABLE_OUTPUT_ESCAPING, PI_ENABLE_OUTPUT_ESCAPING

Field Detail

NIL_IGNORED

public static final int NIL_IGNORED

Constant indicating that xsi:nil is allowed but ignored; this is true when we are validating against a type, rather than against an element declaration

Constant Field Values

NIL_ALLOWED

public static final int NIL_ALLOWED

Constant indicating that xsi:nil is allowed and active. That is, we are validating against an element declaration that specifies nillable=true

Constant Field Values

NIL_DISALLOWED

public static final int NIL_DISALLOWED

Constant indicating that xsi:nil is disallowed. That is, we are validating against an element declaration that specifies nillable=false

Constructor Detail

ContentValidator

public ContentValidator()

Method Detail

getContainingElement

public int getContainingElement()

Get the fingerprint of the name of the element being validated (for diagnostics).

Returns:

the fingerprint, or -1 if not available.

getContainingElementLocationId

public int getContainingElementLocationId()

Get the location ID of the element being validated

Returns:

the location ID, or 0 if not available

getSchemaType

public abstract SchemaType getSchemaType()

Get the schema type against which we are validating, if any

Returns:

the schema type that this validator is validating against, or null

setXSIType

public void setXSIType(SchemaType xsiType)

Set the value of the xsi:type attribute. This is called immediately before the call of startElement on which the xsi:type attribute appears.

Parameters:

xsiType - the schema type identified by the xsi:type attribute

setNamespaceResolver

public void setNamespaceResolver(NamespaceResolver resolver)

Set the NamespaceResolver to be used for resolving QName-valued attributes

Parameters:

resolver - the namespace resolver

getNamespaceResolver

public NamespaceResolver getNamespaceResolver()

Get the namespace resolver

Returns:

the namespace resolver

setNillability

public void setNillability(int nillability)

Set whether this type permits xsi:nil = true

Parameters:

nillability - one of NIL_IGNORED, NIL_ALLOWED, NIL_DISALLOWED

getNillability

public int getNillability()

Determine whether this type permits xsi:nil = true BlockCom

Returns:

one of NIL_IGNORED, NIL_ALLOWED, NIL_DISALLOWED

isNil

public boolean isNil()

Determine whether xsi:nil = true was set on this element

Returns:

true if xsi:nil="true" was set

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 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.

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

makeValidator

public static ContentValidator makeValidator(int nameCode,
                                             int locationId,
                                             SchemaType xsiType,
                                             int validation,
                                             PipelineConfiguration pipe,

xsiType - the type identified by xsi:type, if specified; otherwise null

validation - the validation mode (strict, lax, preserve, strip)

pipe - the pipeline configuration

nextReceiver - the next receiver in the pipeline

Returns:

a Validator suitable for validating the content of this element

Throws:

XPathException

makeValidator

public static ContentValidator makeValidator(ElementDecl elementDecl,
                                             SchemaType schemaType,

Factory method to create a validator for elements of a given type

schemaType - the simple or complex type against which the content of the element is to be validated

pipe - the pipeline configuration

nextReceiver - the next receiver in the pipeline

Returns:

a Validator that can sit in the event pipeline to perform local validation of elements declared to have this type

Throws:

ValidationException

endDocument

public void endDocument()
                 throws XPathException

Notify the end of a document node

XPathException
