Class EnumerationFacet

java.lang.Object

com.saxonica.ee.schema.Facet

com.saxonica.ee.schema.EnumerationFacet

public class EnumerationFacet
extends Facet

Represents a single enumeration facet defined on a simple type. Note that unlike other facets, a value cannot be validated against a single enumeration facet; for this reason all the individual enumeration facets are assembled into an EnumerationFacetSet which is a pseudo-facet used to perform the validation.

EnumerationFacet

public EnumerationFacet()

Method Detail

getName

public String getName()

Get the name of this facet

Specified by:

getName in class Facet

Returns:

"enumeration"

getValue

public String getValue()

Returns the lexical representation of this facet

Specified by:

getValue in class Facet

Returns:

the value of this facet

getNamespaceContext

public NamespaceResolver getNamespaceContext()

Get the namespace context of the value

Returns:

the namespace context from the xs:enumeration element that defined the value

setValue

public void setValue(String value)

Set the value of this facet

Parameters:

value - the raw enumeration value as written in the schema

getTypedValue

public AtomicSequence getTypedValue(SimpleType type,
                           ConversionRules rules)
                             throws SchemaException,
                                    UnresolvedReferenceException

Get the typed value of the enumeration value

Parameters:

type - the simple type containing this facet

rules - the conversion rules for the configuration

Returns:

the enumeration value as written, converted to the simple type on which it appears. If the value is not valid against the type, throws a SchemaException

Throws:

SchemaException - if the schema is invalid

UnresolvedReferenceException - if an unresolved reference to a schema component is encountered

checkFacetRestriction

public void checkFacetRestriction(UserSimpleType type,
                         SimpleType base,
                         SchemaCompiler compiler)
                           throws SchemaException,
                                  UnresolvedReferenceException

Check that this facet is legal when used on a type derived by restriction

Overrides:

checkFacetRestriction in class Facet

Parameters:

base - the type from which the restricted type is derived

compiler - the schema compiler

type - the type on which the facet is defined

Throws:

SchemaException - if the facet value is not legal given the base type

UnresolvedReferenceException

setNamespaceContext

public void setNamespaceContext(NamespaceResolver map)

Save the namespace context for this enumeration value. For internal use only.

Parameters:

map - a NamespaceResolver mapping namespace prefixes (as strings) onto namespace URIs (as strings)

testAtomicValue

public boolean testAtomicValue(AtomicValue value)

Test whether an atomic value conforms to this facet

Specified by:

testAtomicValue in class Facet

Parameters:

value - the value to be tested

Returns:

true if the value conforms; false if it doesn't conform, or if the test fails. The implementation of this method is called only while testing whether the enumeration values themselves conform to the type, so it always returns true.

getFacetAsFunctionItem

public FunctionItem getFacetAsFunctionItem()

Description copied from class: Facet

Get a function item that represents this Facet schema component.

Specified by:

getFacetAsFunctionItem in class Facet
