All Implemented Interfaces:

Result, Receiver

public class ComplexContentValidator
extends AttributeValidator

This class is a filter that is used to validate the content of an element with a complex type. As each child element is encountered, it is used to compute a transition in the finite state machine compiled for the given complex type.

Constructor Details

ComplexContentValidator

public ComplexContentValidator(ElementDecl declaration,
 UserComplexType type,
 Receiver next)
                        throws MissingComponentException

Create a ComplexContentValidator for a given type

Parameters:

declaration - the element declaration, if available, or null otherwise.

type - the complex type

next - the next receiver in the pipeline

Throws:

MissingComponentException - if the schema is incomplete or invalid

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

setSchemaType

public void setSchemaType(UserComplexType type)
                   throws MissingComponentException

Set the schema type against which this validator is to validate the instance element

Parameters:

type - the schema type used for validation

Throws:

MissingComponentException - if there is a problem with the schema

getSchemaType

public SchemaType getSchemaType()

Description copied from class: ContentValidator

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

Specified by:

getSchemaType in class ContentValidator

Returns:

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

startElement

public void startElement(NodeName elemName,
 SchemaType elemType,
 AttributeMap attributes,
 NamespaceMap namespaces,
 Location location,
 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 AttributeValidator

Parameters:

elemName - the name of the element.

elemType - 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

getChildValidator

protected ContentValidator getChildValidator()

Get a validator to handle the children of the current element. This is called immediately on return from the startElement call that starts this element.

Specified by:

getChildValidator in class ContentValidator

Returns:

the validator to be used to handle the children

characters

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

Handle character data appearing as a child of the element being validated

Specified by:

characters in interface Receiver

Overrides:

characters in class AttributeValidator

Parameters:

chars - The character content

locationId - the location of the node in the source, or of the instruction that created it

properties - Additional properties @throws XPathException If this element does not allow character data

Throws:

XPathException - if an error occurs

endElement

public void endElement()
                throws XPathException

Validation at the end of the element being validated. (Note this is a different element from the one passed to startElement).

Specified by:

endElement in interface Receiver

Overrides:

endElement in class ProxyReceiver

Throws:

XPathException - if the element is invalid
