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 Detail

ComplexContentValidator

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

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:

ValidationException - if the schema is incomplete or invalid

Method Detail

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 ValidationException

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

Parameters:

type - the schema type used for validation

Throws:

ValidationException - 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 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 AttributeValidator

Parameters:

elemName - 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 - 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(CharSequence chars,
              int 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

properties - Additional properties

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 this element does not allow character data

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
