Method Detail

### isListType

    public boolean isListType()

  Test whether this Simple Type is a list type

  Returns:
    true if this is a list type

### isUnionType

    public boolean isUnionType()

  Test whether this Simple Type is a union type

  Returns:
    true if this is a union type

### getCommonAtomicType

    public AtomicType getCommonAtomicType()

  Get the most specific possible atomic type that all items in this SimpleType belong to

  Returns:
    the lowest common supertype of all member types

### getBuiltInBaseType

    public SchemaType getBuiltInBaseType()
                                  throws ValidationException

  Throws:
    `ValidationException`

### getTypedValue

    public SequenceIterator getTypedValue(java.lang.CharSequence value,
                                          NamespaceResolver resolver)
                                   throws ValidationException

  Get the typed value corresponding to a given string value, assuming it is valid against this type

  Parameters:
    `value` - the string value
    `resolver` - a namespace resolver used to resolve any namespace prefixes appearing in the content of values. Can supply null, in which case any namespace-sensitive content will be rejected.
  Returns:
    an iterator over the atomic sequence comprising the typed value. The objects returned by this SequenceIterator will all be of type `AtomicValue`
  Throws:
    `ValidationException`

### validateContent

    public ValidationException validateContent(java.lang.CharSequence value,
                                               NamespaceResolver nsResolver)

  Check whether a given input string is valid according to this SimpleType

  Parameters:
    `value` - the input string to be checked
    `nsResolver` - a namespace resolver used to resolve namespace prefixes if the type is namespace sensitive. The value supplied may be null; in this case any namespace-sensitive content will throw an UnsupportedOperationException.
  Returns:
    null if validation succeeds; return a ValidationException describing the validation failure if validation fails. Note that the exception is returned rather than being thrown.
  Throws:
    `java.lang.UnsupportedOperationException` - if the type is namespace-sensitive and no namespace resolver is supplied

### isNamespaceSensitive

    public boolean isNamespaceSensitive()

  Test whether this type is namespace sensitive, that is, if a namespace context is needed to translate between the lexical space and the value space. This is true for types derived from, or containing, QNames and NOTATIONs

  Returns:
    true if the type is namespace-sensitive

### getWhitespaceAction

    public int getWhitespaceAction()

  Determine how values of this simple type are whitespace-normalized.

  Returns:
    one of `Whitespace.PRESERVE`, `Whitespace.COLLAPSE`, `Whitespace.REPLACE`.
