public class UserUnionType
A class that represents the XML Schema simple-type with variety union.
A "plain" union is a union that is not derived by restriction and whose
member types are all either atomic types or plain union types. Only plain union
types can be named in the XPath SequenceType production. (All union types, however,
can act as the target of a cast expression). This class implements the interface
PlainType
despite the fact that not all its instances represent plain
unions; to test whether a union is a plain union, use the isPlainType()
method.

Creates a new Union type. |
Method Summary | |
---|---|
void |
addMemberTypeReference(TypeReference member)
Add a member type to the list of member types |
void |
elaborate(SchemaCompiler compiler)
Elaborate the schema component: after reloading a serialized schema component model, this expands the component with derived information needed during validation episodes. |
PlainType |
getAtomizedItemType()
Get the item type of the atomic values that will be produced when an item of this type is atomized |
double |
getDefaultPriority()
Determine the default priority of this item type when used on its own as a Pattern |
List<TypeReference> |
getMemberTypeReferences()
Get the list of member types |
Set<PlainType> |
getPlainMemberTypes()
Get the set of atomic types that are subsumed by this type |
ItemType |
getPrimitiveItemType()
Method defined in ItemType: get a primitive supertype in the ItemType type hierarchy |
int |
getPrimitiveType()
Method defined in ItemType: get a primitive supertype in the ItemType type hierarchy |
ItemType |
getSuperType(TypeHierarchy th)
Method defined in ItemType: get a supertype in the ItemType type hierarchy |
SequenceIterator<AtomicValue> |
getTypedValue(CharSequence value,
NamespaceResolver resolver,
ConversionRules rules)
Get the typed value corresponding to a given string value, assuming it is valid against this type |
boolean |
isAtomicType()
Test whether this Simple Type is an atomic type |
boolean |
isAtomizable()
Ask whether values of this type are atomizable |
boolean |
isBuiltInType()
Determine whether this is a built-in type or a user-defined type |
boolean |
isIdRefType()
Ask whether this type is an IDREF or IDREFS type. |
boolean |
isIdType()
Ask whether this type is an ID type. |
boolean |
isListType()
Determine whether this is a list type |
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. |
boolean |
isPlainType()
Ask whether this Union type is a "plain type", defined as a union type whose member types are all atomic types or plain unions. |
boolean |
isUnionType()
Return true if this type is a union type (that is, if its variety is union) |
Iterator<TypeReference> |
iterateMemberTypeReferences()
Returns an Iterator over all the SimpleTypes that are members of a union type. |
void |
lookForCycles(Stack references,
SchemaCompiler compiler)
This method is called to look for cycles. |
boolean |
matches(Item item,
XPathContext context)
Test whether a given item conforms to this type |
boolean |
matchesItem(Item item,
boolean allowURIPromotion,
Configuration config)
Test whether a given item conforms to this type |
void |
serializeVariety(SchemaModelSerializer serializer)
Serialize the schema component |
void |
setMemberTypeReferences(List<TypeReference> members)
Set the member types of this union type. |
String |
toString()
|
String |
toString(NamePool pool)
Produce a representation of this type name for use in error messages. |
boolean |
validate(SchemaCompiler compiler)
Validate this Union, replacing all unresolved forwards references at the same time |
ValidationFailure |
validateContent(CharSequence value,
NamespaceResolver nsResolver,
ConversionRules rules)
Check whether a given input string is valid according to this SimpleType |
void |
visitNamedSchemaComponents(SchemaComponentVisitor visitor)
Visit all the schema components used in this ItemType definition |
