Method Detail

### getPrimitiveKind

    public short getPrimitiveKind()

  return an ID representing the built-in primitive base type. REVISIT: This method is (currently) for internal use only. the constants returned from this method are not finalized yet. the names and values might change in the further.
  Returns:
    an ID representing the built-in primitive base type

### validate

    public java.lang.Object validate(java.lang.String content,
                                     ValidationContext context,
                                     ValidatedInfo validatedInfo)
                              throws InvalidDatatypeValueException

  validate a given string against this simple type.
  Parameters:
    `content` - the string value that needs to be validated
    `context` - the validation context
    `validatedInfo` - used to store validation result
  Returns:
    the actual value (QName, Boolean) of the string value

### validate

    public java.lang.Object validate(java.lang.Object content,
                                     ValidationContext context,
                                     ValidatedInfo validatedInfo)
                              throws InvalidDatatypeValueException

  validate a given string value, represented by content.toString(). note that if content is a StringBuffer, for performance reasons, it's possible that the content of the string buffer is modified.
  Parameters:
    `content` - the string value that needs to be validated
    `context` - the validation context
    `validatedInfo` - used to store validation result
  Returns:
    the actual value (QName, Boolean) of the string value

### validate

    public void validate(ValidationContext context,
                         ValidatedInfo validatedInfo)
                  throws InvalidDatatypeValueException

  Validate an actual value against this simple type.
  Parameters:
    `context` - the validation context
    `validatedInfo` - used to provide the actual value and member types
  Throws:
    `InvalidDatatypeValueException` - exception for invalid values.

### applyFacets

    public void applyFacets(XSFacets facets,
                            short presentFacet,
                            short fixedFacet,
                            ValidationContext context)
                     throws InvalidDatatypeFacetException

  If this type is created from restriction, then some facets can be applied to the simple type. `XSFacets` is used to pass the value of different facets.
  Parameters:
    `facets` - the value of all the facets
    `presentFacet` - bit combination value of the costraining facet constants which are present.
    `fixedFacet` - bit combination value of the costraining facet constants which are fixed.
    `context` - the validation context
  Throws:
    `InvalidDatatypeFacetException` - exception for invalid facet values.

### isEqual

    public boolean isEqual(java.lang.Object value1,
                           java.lang.Object value2)

  Check whether two actual values are equal.
  Parameters:
    `value1` - the first value
    `value2` - the second value
  Returns:
    true if the two value are equal

### isIDType

    public boolean isIDType()

  Check whether this type is or is derived from ID. REVISIT: this method makes ID special, which is not a good design. but since ID is not a primitive, there doesn't seem to be a clean way of doing it except to define special method like this.
  Returns:
    whether this simple type is or is derived from ID.

### getWhitespace

    public short getWhitespace()
                        throws DatatypeException

  Return the whitespace corresponding to this datatype.
  Returns:
    valid values are WS_PRESERVE, WS_REPLACE, WS_COLLAPSE.
  Throws:
    `DatatypeException` - union datatypes don't have whitespace facet associated with them
