Enum AnyType

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<AnyType>, ComplexType, SchemaComponent, SchemaType
    public enum AnyType
extends java.lang.Enum<AnyType>
implements ComplexType
    This class has a singleton instance which represents the XML Schema built-in type xs:anyType, also known as the urtype.

    See XML Schema 1.1 Part 1 section 3.4.7

    • Enum Constant Detail

      • INSTANCE

        public static final AnyType INSTANCE

    • Method Detail

      • values

        public static AnyType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static AnyType valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • getInstance

        public static AnyType getInstance()
        Get the singular instance of this class

        the singular object representing xs:anyType

        public java.lang.String getName()
        Get the local name of this type
        Specified by:
        getName in interface SchemaType
        Returns:
        the local name of this type definition, if it has one. Return null in the case of an anonymous type.

      • getEQName

        public java.lang.String getEQName()
        Get the name of this type as an EQName, that is, a string in the format Q{uri}local.

      • 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

                            throws java.lang.IllegalStateException
        Returns the base type that this type inherits from. This method can be used to get the base type of a type that is known to be valid. If this type is a Simpletype that is a built in primitive type then null is returned.
        Returns:
        the base type.
        Throws:
        java.lang.IllegalStateException - if this type is not valid.

      • getDerivationMethod

      • getComponentAsFunction

        public Function getComponentAsFunction()
        Get the schema component in the form of a function item. This allows schema information to be made visible to XSLT or XQuery code. The function makes available the contents of the schema component as defined in the XSD specification. The function takes a string as argument representing a property name, and returns the corresponding property of the schema component. There is also a property "class" which returns the kind of schema component, for example "Attribute Declaration".
        Specified by:
        getComponentAsFunction in interface SchemaComponent
        Returns:
