```
public AtomicSequence atomize(NodeInfo node)
                       throws XPathException
```
    Get the typed value of a node that is annotated with this schema type.
    
    Specified by:
    
    atomize in interface SchemaType
    
    Parameters:
    
    node - the node whose typed value is required
    
    Returns:
    
    the typed value.
    
    Throws:
    
    XPathException - if the node cannot be atomized, for example if this is a complex type with element-only content
    
    Since:
    
    8.5. Changed in 9.5 to return the new type AtomicSequence
  - isSameType
```
public boolean isSameType(SchemaType other)
```
    Test whether this is the same type as another type. They are considered to be the same type if they are derived from the same type definition in the original XML representation (which can happen when there are multiple includes of the same file)
    
    Specified by:
    
    isSameType in interface SchemaType
    
    Parameters:
    
    other - the other type
    
    Returns:
    
    true if this is the same type as other
  - getDescription
```
public java.lang.String getDescription()
```
    Get a description of this type for use in error messages. This is the same as the display name in the case of named types; for anonymous types it identifies the type by its position in a source schema document.
    
    Specified by:
    
    getDescription in interface SchemaType
    
    Returns:
    
    text identifing the type, for use in a phrase such as "the type XXXX".
  - checkTypeDerivationIsOK
```
public void checkTypeDerivationIsOK(SchemaType base,
                                    int block)
                             throws SchemaException
```
    Check that this type is validly derived from a given type, following the rules for the Schema Component Constraint "Is Type Derivation OK (Simple)" (3.14.6) or "Is Type Derivation OK (Complex)" (3.4.6) as appropriate.
    
    Specified by:
    
    checkTypeDerivationIsOK in interface SchemaType
    
    Parameters:
    
    base - the base type; the algorithm tests whether derivation from this type is permitted
    
    block - the derivations that are blocked by the relevant element declaration
    
    Throws:
    
    SchemaException - if the derivation is not allowed
  - getSystemId
```
public java.lang.String getSystemId()
```
    Get the URI of the schema document where the type was originally defined.
    
    Specified by:
    
    getSystemId in interface SchemaType
    
    Returns:
    
    the URI of the schema document. Returns null if the information is unknown or if this is a built-in 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 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
    
    Returns:
    
    true if this type is an ID type
  - isIdRefType
```
public boolean isIdRefType()
```
    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
    
    Returns:
    
    true if this type is an IDREF type
  - getValidationStatus
```
public int getValidationStatus()
```
    Get the validation status of this component.
    
    Specified by:
    
    getValidationStatus in interface SchemaComponent
    
    Returns:
    
    one of the values SchemaComponent.UNVALIDATED, SchemaComponent.VALIDATING, SchemaComponent.VALIDATED, SchemaComponent.INVALID, SchemaComponent.INCOMPLETE
  - 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
  - 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:
    
    the schema component represented as a function from property names to property values.
  - toString
```
public java.lang.String toString()
```
    Specified by:
    
    toString in interface ItemType
    
    Overrides:
    
    toString in class java.lang.Object
  - toExportString
```
public java.lang.String toExportString()
```
    Return a string representation of this SequenceType suitable for use in export (SEF) files. The difference from the toString() method is that the representation will not contain references to anonymous types.
    
    Specified by:
    
    toExportString in interface ItemType
    
    Returns:
    
    the string representation as an instance of the XPath SequenceType construct, using only names that will be in-scope if the target environment imports the same schema as the source environment
  - generateJavaScriptItemTypeTest
```
public java.lang.String generateJavaScriptItemTypeTest(ItemType knownToBe,
                                                       int targetVersion)
```
    Generate Javascript code to test whether an item conforms to this item type
    
    Specified by:
    
    generateJavaScriptItemTypeTest in interface ItemType
    
    Parameters:
    
    knownToBe -
    
    targetVersion -
    
    Returns:
    
    a Javascript instruction or sequence of instructions, which can be used as the body of a Javascript function, and which returns a boolean indication whether the value of the variable "item" is an instance of this item type.
  - generateJavaScriptItemTypeAcceptor
```
public java.lang.String generateJavaScriptItemTypeAcceptor(java.lang.String errorCode,
                                                           int targetVersion)
                                                    throws XPathException
```
    Generate Javascript code to convert a supplied Javascript value to this item type, if conversion is possible, or throw an error otherwise.
    
    Specified by:
    
    generateJavaScriptItemTypeAcceptor in interface ItemType
    
    Parameters:
    
    errorCode - the error to be thrown if conversion is not possible
    
    targetVersion -
    
    Returns:
    
    a Javascript instruction or sequence of instructions, which can be used as the body of a Javascript function, and which returns the result of conversion to this type, or throws an error if conversion is not possible. The variable "val" will hold the supplied Javascript value.
    
    Throws:
    
    XPathException
