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(SchemaAwareConfiguration 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

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

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

Throws:
XPathException
