public class SimpleTypeDefinition
extends UserSimpleType
implements UserSchemaComponent

A simple type definition holds all the information about a simpleType during the course of schema processing. On completion of schema processing, more specific objects are created, for example ListType, AtomicType, or UnionType, and the SimpleTypeDefinition is then discarded.

Constructor Detail

SimpleTypeDefinition

public SimpleTypeDefinition(SchemaAwareConfiguration config)
Create a SimpleTypeDefinition

Parameters:
config - the Saxon configuration
Method Detail

setItemTypeReference

public void setItemTypeReference(TypeReference itemType)
Set the reference to an item type of this list type

Parameters:
itemType - reference to a type forming the item type of this list type

setIsSimpleContent

public void setIsSimpleContent(boolean b)
Indicate that this simple type represents the content type of a complex type with simple content

Parameters:
b - true if this is the content type of a complex type with simple content

addMemberType

public void addMemberType(TypeReference memberType)
Add a member type to this union type

Parameters:
memberType - the member type to be added

getSimpleType

public UserSimpleType getSimpleType()
Get the simple type created for this definition

Returns:
the UserSimpleType object if it has been created, otherwise null

getCommonAtomicType

public AtomicType getCommonAtomicType()
Get the most specific possible atomic type that all items in this SimpleType belong to

Specified by:
getCommonAtomicType in interface SimpleType
Returns:
the lowest common supertype of all member types

fixup

public boolean fixup(SchemaCompiler compiler)
              throws SchemaException
Check references from this component to other components

Specified by:
fixup in interface UserSchemaComponent
Overrides:
fixup in class SchemaStructure
Parameters:
compiler - used for error reporting
Returns:
true if all is well, false if errors found
Throws:
SchemaException

validate

public boolean validate(SchemaCompiler compiler)
                 throws SchemaException
Checks the validity of this SimpleType definition.

Specified by:
validate in interface UserSchemaComponent
Overrides:
validate in class UserSimpleType
Parameters:
compiler - used for error reporting
Returns:
true when this Schema definition is valid, otherwise false.
Throws:
SchemaException - when this SimpleType definition is invalid.

getTypedValue

public SequenceIterator getTypedValue(CharSequence value,
                                      NamespaceResolver resolver,
                                      NameChecker nameChecker)
                               throws ValidationException
Get the typed value corresponding to a given string value, assuming it is valid against this type

Specified by:
getTypedValue in interface SimpleType
Parameters:
value - the string value
resolver - a namespace resolver used to resolve prefixes in QNames and notations
nameChecker - used to check names against XML 1.0 or XML 1.1 rules
Returns:
an iterator over the atomic sequence comprising the typed value
Throws:
ValidationException - if the supplied value is not in the lexical space of the data type

isBuiltInType

public boolean isBuiltInType()
Determine whether this is a built-in type or a user-defined type

Specified by:
isBuiltInType in interface SimpleType
Returns:
true if this is a built-in type

isNamespaceSensitive

public boolean isNamespaceSensitive()
Test whether this type is namespace sensitive, that is, if a namespace context is needed to translate between the lexical space and the value space. This is true for types derived from, or containing, QNames and NOTATIONs

Specified by:
isNamespaceSensitive in interface SimpleType
Returns:
true if the type is namespace-sensitive

validateContent

public ValidationFailure validateContent(CharSequence value,
                                         NamespaceResolver nsResolver,
                                         NameChecker nameChecker)
Check whether a given input string is valid according to this SimpleType

Specified by:
validateContent in interface SimpleType
Parameters:
value - the input string to be checked
nsResolver - a namespace resolver used to resolve namespace prefixes if the type is namespace sensitive. The value supplied may be null; in this case any namespace-sensitive content will throw an UnsupportedOperationException.
nameChecker - Used to check the syntax of names against the XML 1.0 or XML 1.1 rules
Returns:
null if validation succeeds; return a ValidationFailure describing the validation failure if validation fails. Note that the exception is returned rather than being thrown.
Throws:
UnsupportedOperationException - if the type is namespace-sensitive and no namespace resolver is supplied

serialize

public void serialize(SchemaModelSerializer serializer)
Serialize the schema component

Specified by:
serialize in interface SerializableSchemaComponent
Overrides:
serialize in class UserSimpleType
