Constructor Detail

### DigitsFacet

    public DigitsFacet(int facetType)

  Construct a totalDigits or fractionDigits facet. For internal use only.

  Parameters:
    `facetType` - indicates which facet to construct. One of `TOTAL_DIGITS` or `FRACTION_DIGITS`

Method Detail

### getName

    public String getName()

  Get the name of this facet

  Overrides:
    `getName` in class `Facet`
  Returns:
    either "totalDigits" or "fractionDigits"

### getValue

    public String getValue()

  Get the value of this facet as a string

  Overrides:
    `getValue` in class `Facet`
  Returns:
    the value of this facet as a string

### setValue

    public void setValue(String value)
                  throws SchemaException

  Set the value of this facet. For internal use only.

  Parameters:
    `value` - the value of the facet. This must be a string that parses as an integer.
  Throws:
    `SchemaException` - if the value is invalid (not an integer)

### checkFacetRestriction

    public void checkFacetRestriction(UserSimpleType type,
                                      SimpleType base)
                               throws SchemaException,
                                      ValidationException

  Check that this facet is legal when used on a type derived by restriction

  Overrides:
    `checkFacetRestriction` in class `Facet`
  Parameters:
    `base` - the type from which the restricted type is derived
    `type` - the type on which the facet is defined
  Throws:
    `SchemaException` - if the facet is not allowed for this simple type, or if the combination of facets is inconsistent with values defined on the base type.
    `ValidationException`

### testAtomicValue

    public boolean testAtomicValue(AtomicValue value)

  Test whether an atomic value conforms to this facet

  Overrides:
    `testAtomicValue` in class `Facet`
  Parameters:
    `value` - the value to be tested
  Returns:
    true if the value conforms; false if it doesn't conform
