public class UserListType
extends UserSimpleType
implements ListType

Represents a SimpleType that is a list of a given SimpleType, known as its itemType. A ListType may be a restriction of another ListType; the itemType must either be an AtomicType or a UnionType whose members are not list types.

This class is not used to implement the built-in list types NMTOKENS, ENTITIES, IDREFS.

Constructor Detail

UserListType

public UserListType(EnterpriseConfiguration config)

Create a new user-defined ListType.

Parameters:

config - the Saxon configuration

Method Detail

isAtomicType

public boolean isAtomicType()

Test whether this Simple Type is an atomic type

Specified by:

isAtomicType in interface SchemaType

Specified by:

isAtomicType in interface SimpleType

Overrides:

isAtomicType in class UserSimpleType

Returns:

false, this is not an atomic type

isIdType

public boolean isIdType()

Ask whether this type is an ID type. This is defined to be any simple type who typed value may contain atomic values of type xs:ID: that is, it includes types derived from ID by restriction, list, or union. Note that for a node to be treated as an ID, its typed value must be a *single* atomic value of type ID; the type of the node, however, can still allow a list.

Specified by:

isIdType in interface SchemaType

Overrides:

isIdType in class UserSimpleType

isIdRefType

public boolean isIdRefType()

Ask whether this type is an IDREF or IDREFS type. This is defined to be any simple type who typed value may contain atomic values of type xs:IDREF: that is, it includes types derived from IDREF or IDREFS by restriction, list, or union

Specified by:

isIdRefType in interface SchemaType

Overrides:

isIdRefType in class UserSimpleType

isBuiltInType

public boolean isBuiltInType()

Determine whether this is a built-in type or a user-defined type

Specified by:

isBuiltInType in interface SimpleType

Returns:

true if this is a built-in type

isListType

public boolean isListType()

Returns true if this type is derived by list, or if it is derived by restriction from a list type, or if it is a union that contains a list as one of its members

Specified by:

isListType in interface SimpleType

Overrides:

isListType in class UserSimpleType

Returns:

true if this is a list type

addInheritedFacets

protected List<Facet> addInheritedFacets(List<Facet> localFacets)

Get the extended facet list, creating it if necessary. The extended facet list includes facets inherited from supertypes, unless they are redundant

Overrides:

addInheritedFacets in class UserSimpleType

Returns:

the extended facet list

elaborate

public void elaborate(SchemaCompiler compiler)
               throws SchemaException

Description copied from class: UserSimpleType

Elaborate the schema component: after reloading a serialized schema component model, this expands the component with derived information needed during validation episodes. The model is assumed to be valid.

Specified by:

elaborate in interface UserSchemaComponent

Overrides:

elaborate in class UserSimpleType

Throws:

SchemaException

getItemTypeReference

public TypeReference getItemTypeReference()

Get the reference to the item type of the list

Returns:

the type reference

getItemType

public SimpleType getItemType()
                       throws UnresolvedReferenceException

Returns the simpleType of the items in this ListType. This method assumes that the item type has been fully resolved

Specified by:

getItemType in interface ListType

Returns:

the simpleType of the items in this ListType. This will either be an AtomicType or a UnionType

Throws:

UnresolvedReferenceException - if the item type has not been fully resolved

getCommonAtomicType

public AtomicType getCommonAtomicType()

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

Specified by:

getCommonAtomicType in interface SimpleType

Returns:

the lowest common supertype of all member types

setItemTypeReference

public void setItemTypeReference(TypeReference type)

Sets the itemType for this ListType (the type of item that instances of this list type contain). For internal use only.

Parameters:

type - the SimpleType for this ListType.

validateContent

public ValidationFailure validateContent(CharSequence value,
                                         NamespaceResolver nsResolver,
                                         NameChecker nameChecker)

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

Specified by:

validateContent in interface 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.

nameChecker - XML 1.0 or 1.1 name checker, needed when validating against version-sensitive types such as xs:NCName

Returns:

null if validation succeeds; return a ValidationException describing the validation failure if validation fails, unless throwException is true, in which case the exception is thrown rather than being returned.

Throws:

UnsupportedOperationException - if the type is namespace-sensitive and no namespace resolver is supplied

getTypedValue

public SequenceIterator getTypedValue(CharSequence value,
                                      NamespaceResolver resolver,
                                      NameChecker nameChecker)
                               throws ValidationException

Get the typed value of a given input string. This method assumes that the input value is valid according to this SimpleType

Specified by:

getTypedValue in interface SimpleType

Parameters:

value - the string whose typed value is required

resolver - namespace resolver

nameChecker - XML 1.0 or 1.1 name checker

Returns:

an iterator over the atomic sequence comprising the typed value. The objects returned by this SequenceIterator will all be of type AtomicValue, The next() method on the iterator throws no checked exceptions, although it is not actually declared as an UnfailingIterator.

Throws:

ValidationException - if the supplied value is not in the lexical space of the data type

isNamespaceSensitive

public boolean isNamespaceSensitive()

Test whether this simple type is namespace-sensitive, that is, whether the item types is derived from xs:QName or xs:NOTATION

Specified by:

isNamespaceSensitive in interface SimpleType

Returns:

true if the item type is derived from xs:QName or xs:NOTATION

serializeVariety

public void serializeVariety(SchemaModelSerializer serializer)
                      throws XPathException

Serialize the schema component

Specified by:

serializeVariety in class UserSimpleType

Throws:

XPathException
