Class BuiltInListType

  • All Implemented Interfaces:
    CastingTarget, HyperType, ListType, SchemaComponent, SchemaType, SimpleType

    public class BuiltInListType
    extends java.lang.Object
    implements ListType

    This class is used to implement the built-in list types NMTOKENS, ENTITIES, IDREFS. It is also used to represent the anonymous type of the xsi:schemaLocation attribute (a list of xs:anyURI values).

    • Constructor Detail

      • BuiltInListType

        public BuiltInListType​(int fingerprint)
        Create a new ListType.
        Parameters:
        fingerprint - identifies the name of the type
    • Method Detail

      • 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
      • getSystemId

        public java.lang.String getSystemId()
        Get the URI of the schema document containing the definition of this type
        Specified by:
        getSystemId in interface SchemaType
        Returns:
        null for a built-in type
      • getRedefinitionLevel

        public int getRedefinitionLevel()
        Get the redefinition level. This is zero for a component that has not been redefined; for a redefinition of a level-0 component, it is 1; for a redefinition of a level-N component, it is N+1. This concept is used to support the notion of "pervasive" redefinition: if a component is redefined at several levels, the top level wins, but it is an error to have two versions of the component at the same redefinition level.
        Specified by:
        getRedefinitionLevel in interface SchemaComponent
        Returns:
        the redefinition level
      • getBaseType

        public SchemaType getBaseType()
        Returns the base type that this type inherits from. If this type is a Simpletype that is a built in primitive type then null is returned.
        Specified by:
        getBaseType in interface SchemaType
        Returns:
        the base type.

        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.

        isNamespaceSensitive in interface HyperType
        Returns:
