- 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.

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 valuestype
- The schema type of the element
- Throws:
ValidationException
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 contentproperties
- Additional propertieslocationId
- 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
