    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)
                           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(int nameCode,
                             int 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`

### 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`
