    Test whether this is an anonymous type
    
    Specified by:
    
    isAnonymousType in interface SchemaType
    
    Returns:
    
    true if this SchemaType is an anonymous type
  - getBlock
```
public int getBlock()
```
    Returns the value of the 'block' attribute for this type, as a bit-significant integer with fields such as Derivation.DERIVATION_LIST and Derivation.DERIVATION_EXTENSION. This corresponds to the property "prohibited substitutions" in the schema component model.
    
    Specified by:
    
    getBlock in interface SchemaType
    
    Returns:
    
    the value of the 'block' attribute for this type
  - getBaseType
```
public SchemaType getBaseType()
```
    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.
    
    Specified by:
    
    getBaseType in interface SchemaType
    
    Returns:
    
    the base type, or null if this is xs:anyType (the root of the type hierarchy)

    Gets the integer code of the derivation method used to derive this type from its parent. Returns zero for primitive types.
    
    Specified by:
    
    getDerivationMethod in interface SchemaType
    
    Returns:
    
    a numeric code representing the derivation method, for example Derivation.DERIVATION_RESTRICTION
  - getFinalProhibitions
```
public int getFinalProhibitions()
```
    Get the types of derivation that are not permitted, by virtue of the "final" property.
    
    Specified by:

```
public void analyzeContentExpression(Expression expression,
                                     int kind)
                              throws XPathException
```
    Analyze an XPath expression to see whether the expression is capable of delivering a value of this type. This method is called during static analysis of a query or stylesheet to give compile-time warnings when "impossible" paths are used.
    
    Specified by:
    
    analyzeContentExpression in interface SchemaType
    
    Parameters:
    
    expression - the expression that delivers the content
    
    kind - the node kind whose content is being delivered: Type.ELEMENT, Type.ATTRIBUTE, or Type.DOCUMENT
    
    Throws:
    
    XPathException - if the expression will never deliver a value of the correct type
  - atomize
```
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
  - getValidationStatus
```
public SchemaValidationStatus getValidationStatus()
```
    Get the validation status of this component.
    
    Specified by:
    
    getValidationStatus in interface SchemaComponent
    
    Returns:
    
    one of the values SchemaValidationStatus.UNVALIDATED, SchemaValidationStatus.VALIDATING, SchemaValidationStatus.VALIDATED, SchemaValidationStatus.INVALID, SchemaValidationStatus.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.
