## Interface SchemaType

- All Superinterfaces:
    SchemaAnnotated, SchemaComponent
  All Known Implementing Classes:
    SchemaTypeImpl

      public interface SchemaType
      extends SchemaComponent, SchemaAnnotated

  Represents a schema type.

  SchemaType is the metadata "type" class for `XmlObject`, and it plays the analogous role for `XmlObject` that `Class` plays for `Object`.

  Every XML Bean class corresponds to a singleton SchemaType object obtainable by ClassName.type (e.g., `XmlNonPositiveInteger.type`), and every XML Bean instance has an actual SchemaType, obtainable by `XmlObject.schemaType()`. The ClassName.type and schemaType() mechanisms are analogous to the ordinary Java ClassName.class and obj.getClass() mechanisms.

  All schema types are represented by a SchemaType, this includes all types regardless of whether they are built-in or user-defined, compiled or uncompiled, simple or complex.

  In addition, a compiled XML Bean type system includes special "document" schema types each representing a document containing nothing but a single element for each global element, and special "attribute" schema types each representing a fragment containing nothing but a single global attribute for global attribute.

  Do not confuse Schema Types with other types of Schema Components such as `Global Elements`, `Global Attributes`, `Named Model Groups`, or `Attribute Groups`. SchemaType represents a Type component, not any of the other kinds of components. There are different kinds of metadata objects for the different Schema components.

  The space of SchemaTypes is divided as follows:

  - First, there is the universal base type and the universal subtype. These are `XmlObject.type` (corresponding to xs:anyType) and `XmlBeans.NO_TYPE`, respectively. The first type is a base type of all other types. The other type indicates the absence of type information and, at least in set-theoretic terms, is a subtype of all other types.
  - There is another universal base type that is the base type for all simple types. This is the `XmlAnySimpleType.type`, corresponding to xs:anySimpleType. Only XmlObject.type and XmlAnySimpleType.type return `true` for `isURType()`, and only XmlBeans.NO_TYPE returns `true` for `isNoType()`.
  - The two "special" kinds of types that are generated that do not formally exist in the actual Schema specification are document types and global attribute types (corresponding to documents that contain a global element, or fragments that contain a global attribute). They can be detected using `isDocumentType()` and `isAttributeType()`. Other than their anonymity (lack of a type name) and their appearance only at the root of an instance, they are otherwise just like ordinary complex types.
  - Simple types can be detected using `isSimpleType()`. Complex types are considered to be all the types that are not simple.
  - Simple types are divided into three varieties: atomic types, list types, and union types. Which variety of simple type you have can be discoverd using `getSimpleVariety()`. It will return either `ATOMIC`, `LIST`, or `UNION`.
  - An `ATOMIC` simple type is always based on one of the 20 built-in primitive schema types. You can determine the underlying primitive type for an atomic simple type by calling `getPrimitiveType()`. An atomic type may add facet restrictions on top of the primitive type, and these facets can be explored using `getFacet(int)`, `getWhiteSpaceRule()`, `matchPatternFacet(java.lang.String)`, `getEnumerationValues()`, and related methods.
  - A `LIST` simple type is always based on another non-list simple type. The underlying list item type can be obtained by using `getListItemType()`.
  - A `UNION` simple type is always composed out of a number of other simple types. The direct members of the union can be obtained by `getUnionMemberTypes()`. When unions consist of other unions, it is useful to know useful to know the "leaves of the union tree", so the set of non-union types making up the union can be obtained by `getUnionConstituentTypes()`. The closure of the entire "union tree" is `getUnionSubTypes()` (this includes the type itself). For simple unions that do not consist of other unions, all three of these sets are the same.
  - Complex types have nested structure. They are divided into four content types: empty content, simple content, element-only content, and mixed content. All kinds of complex types may have attributes. The content type for a complex type can be dermined using `getContentType()`. This will return `EMPTY_CONTENT`, `SIMPLE_CONTENT`, `ELEMENT_CONTENT`, or `MIXED_CONTENT`.
  - If a complex type has `EMPTY_CONTENT`, the content model will be null.
  - If a complex type has `SIMPLE_CONTENT`, then it will extend the simple type that describes the content. In addition, the type may impose additional simple type facet restrictions; these can be determined in the same way they are for a simple type.
  - If a complex type has `ELEMENT_CONTENT` or `MIXED_CONTENT`, then the detailed content model can be determined by examining the particle tree (which may be null for MIXED_CONTENT). The particle tree can be obtained via `getContentModel()`.
  - When working with a complex type, most users will find it sufficient to discover the summarized shape of the content model and attribute model using `getElementProperties()`, `getAttributeProperties()`, and related methods rather than examining the particle tree and attribute model directly.

      True if this is a attribute type.

      Attribute types are generated for every global attribute. An attribute type is an unnamed complex type that contains exactly one attribute: we define these types, because they are the types of the "attribute documents" which contain the defined global attribute, and they all turn into Java types. (Named AttributenameAttribute.)

    - #### getTypeSystem

          SchemaTypeSystem getTypeSystem()

      Returns the SchemaTypeLoader in which this type was defined. Complex types are defined and used in exactly one schema type system, but simple types are defined in one type system and can be used in any number of type systems. The most common case is the builtin types, which are defined in the builtin type system and used elsewhere.
      Specified by:

    - #### getElementSequencer

          SchemaTypeElementSequencer getElementSequencer()

      Returns a `SchemaTypeElementSequencer` object, which can then be used to validate complex content inside this element. This is useful for example for trying out different names and see which one would be valid as a child of this element.

    - #### getUnionMemberTypes

          SchemaType[] getUnionMemberTypes()

      For union types only: get the shallow member types. This returns the declared member types of the union, so, for example if the type contains another union, the nested members of that union are NOT returned here.

      Returns null if this type is not a union.

    - #### getUnionSubTypes

          SchemaType[] getUnionSubTypes()

      For union types only: gets the full tree of member types. This computes the closure of the set returned by getUnionMemberTypes(), so, for example, it returns all the types nested within unions of unions as well as the top-level members; the set also includes the type itself. If you are seeking only the basic non-union consituents, use getUnionConstituentTypes.

      Returns null if this type is not a union.

    - #### getUnionConstituentTypes

          SchemaType[] getUnionConstituentTypes()

      For union types only: get the constituent member types. This returns only non-union types, so, for example, for unions of unions, this returns the flattened list of individual member types within the innermost unions.

      Returns null if this type is not a union.

    - #### getUnionCommonBaseType

          SchemaType getUnionCommonBaseType()

      For union types only: get the most specific common base type of the constituent member types. May return a UR type.

      Returns null if this type is not a union.

    - #### getAnonymousUnionMemberOrdinal

          int getAnonymousUnionMemberOrdinal()

      For anonymous types defined inside a union only: gets the integer indicating the declaration order of this type within the outer union type, or zero if this is not applicable. The first anonymous union member within a union type is numbered "1". Used to differentiate between different anonymous types.

    - #### getListItemType

          SchemaType getListItemType()

      For list types only: get the item type. This is the atomic or union type that is the type of every entry in the list.

      Returns null if this type is not a list.

    - #### getWhiteSpaceRule

          int getWhiteSpaceRule()

      For nonunion simple types: get the whitespace rule. This is either `WS_PRESERVE`, `WS_REPLACE`, or `WS_COLLAPSE`. Returns `WS_UNSPECIFIED` for unions and complex types.

    - #### newValue

          XmlAnySimpleType newValue(Object v)

      Creates an immutable simple type value that does not reside in a tree.

    - #### getRef

          SchemaType.Ref getRef()

      Retruns a SchemaType.Ref pointing to this schema type itself.

    - #### qnameSetForWildcardElements

          QNameSet qnameSetForWildcardElements()

      Returns a QNameSet of elements that may exist in wildcard buchets and are not explicitly defined in this schema type. Note: In this example:

           <xs:complexType name="exampleType">

           <xs:element name="someElement" type='xs:string' />
           <xs:any namespace="##targetNamespace" />
           </xs:sequence>
           </xs:complexType>

      the returned QNameSet will not contain the qname of 'someElement'.
      Returns:
        the constructed QNameSet

    - #### qnameSetForWildcardAttributes

          QNameSet qnameSetForWildcardAttributes()

      Returns a QNameSet of attributes that may exist in wildcard buchets and are not explicitly defined in this schema type. Note: In this example:

           <xs:complexType name="exampleType">
           ...
           <xs:attribute name='someAttribute' type='xs:string' />
           <xs:anyAttribute namespace="##targetNamespace" />
           </xs:complexType>

      the returned QNameSet will not contain the qname of 'someAttribute'.
      Returns:
        the constructed QNameSet

    - #### getDocumentation

             <xs:annotation>
                <xs:documentation>
                    getDocumentation method will return whatever stuff here.
                </xs:docmentation>
             </xs:annotation>
           </xs complexType>
