Class UserListType

All Implemented Interfaces:
SerializableSchemaComponent, UserSchemaComponent, SourceLocator, Location, CastingTarget, HyperType, ListType, SchemaComponent, SchemaType, SimpleType, Locator

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 Details

    • UserListType

      public UserListType(EnterpriseConfiguration config)
      Create a new user-defined ListType.
      Parameters:
      config - the Saxon configuration
  • Method Details

    • 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() throws MissingComponentException
      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 in XSD 1.0, its typed value must be a *single* atomic value of type ID; the type of the node, however, can still allow a list. But in XSD 1.1, a list of IDs is permitted
      Specified by:
      isIdType in interface SchemaType
      Overrides:
      isIdType in class UserSimpleType
      Returns:
      true if this type is an ID type
      Throws:
      MissingComponentException
    • isIdRefType

      public boolean isIdRefType() throws MissingComponentException
      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
      Returns:
      true if this type is an IDREF type
      Throws:
      MissingComponentException
    • 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
      Parameters:
      compiler - the schema compiler
      Throws:
      SchemaException - if a fatal error occurs
    • getItemTypeReference

      public TypeReference getItemTypeReference()
      Get the reference to the item type of the list
      Returns:
      the type reference
    • getItemType

      public SimpleType getItemType() throws MissingComponentException
      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:
      MissingComponentException - if the item type has not been fully resolved
    • 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.
    • setTokenSeparator

      public void setTokenSeparator(RegularExpression regex)
      Set the regular expression defined in saxon:separator for tokenizing the supplied value

      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.
      rules - the conversion rules used in this configuration
      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.

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

      public ValidationFailure checkAgainstListFacets(UnicodeString value, NamespaceResolver nsResolver, ConversionRules rules, int count)
      Check whether a supplied value is valid against the facets defined on the list type. This method does NOT check that the items in the list are valid against the item type of the list

      nsResolver - the namespace context
      rules - the conversion rules
      count - the number of items in the list

      Specified by:
      isNamespaceSensitive in interface HyperType
      Returns:
      true if the item type is derived from xs:QName or xs:NOTATION; or if the item type cannot be determined (because it is missing from the schema)
