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

Parameters:
type - the schema type
Throws:
ValidationException - indicates a problem with the schema

startElement

public void startElement(NodeName nameCode,
                         SchemaType typeCode,
                         int locationId,
                         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:
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 - 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(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 the character data is invalid

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
