All Implemented Interfaces:

public class SimpleContentValidator
extends AttributeValidator

This class is a filter that is used to validate that an element has simple content conforming to a given simple type. This filter accumulates the character data in a buffer and invokes the validation method of the simple type at the time that endElement() is called. Child elements are rejected as invalid. This validator can handle simple types, or complex types with simple content: the attributes are validated by the superclass, Validator.

Constructor Detail

SimpleContentValidator

public SimpleContentValidator(ElementDecl declaration,
                              SchemaType type,
                              Receiver next)
                       throws MissingComponentException

Create a simple content validator

Parameters:

declaration - The element declaration (may be null). Used to check fixed/default values

type - The schema type of the element

next - The next receiver in the pipeline

Throws:

MissingComponentException - if a validator cannot be constructed because the schema is incomplete

Method Detail

getSchemaType

public SchemaType getSchemaType()

Get the schema type against which we are validating

Specified by:

getSchemaType in class ContentValidator

Returns:

the schema type

setSchemaType

public void setSchemaType(SchemaType type)
                   throws MissingComponentException

Set the schema type against which this validator is to perform validation

Parameters:

type - the schema type

Throws:

MissingComponentException - if an unresolved reference is present

startElement

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

Output element start tag (for a child of the element being validated)

Specified by:

startElement in interface Receiver

Overrides:

startElement in class AttributeValidator

Parameters:

elemName - the name of the element.

type - 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()

Return a validator to handle the children of the element just started. This will only be called during error recovery, because an exception would have been thrown when the element was started

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 net.sf.saxon.trans.XPathException

Throws:

XPathException - if an error occurs

endElement

public void endElement()
                throws XPathException

End of element being validated

Specified by:

endElement in interface Receiver

Overrides:

endElement in class ProxyReceiver

Throws:

XPathException - if an error occurs
