Interface SimpleType

public interface SimpleType extends SchemaType

This interface represents a simple type, which may be a built-in simple type, or a user-defined simple type.
Method Summary

Method Detail

getBuiltInBaseType

public SchemaType getBuiltInBaseType()

getCommonAtomicType

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

Returns: the lowest common supertype of all member types

getTypedValue

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

Parameters: value the string value resolver a namespace resolver used to resolve any namespace prefixes appearing in the content of values. Can supply null, in which case any namespace-sensitive content will be rejected. nameChecker

Returns: an iterator over the atomic sequence comprising the typed value. The objects returned by this SequenceIterator will all be of type AtomicValue

getWhitespaceAction

public int getWhitespaceAction(TypeHierarchy th)
Determine how values of this simple type are whitespace-normalized.

Parameters: th

Returns: one of PRESERVE, COLLAPSE, REPLACE.

isAtomicType

public boolean isAtomicType()
Test whether this Simple Type is an atomic type

Returns: true if this is an atomic type

isListType

public boolean isListType()
Test whether this Simple Type is a list type

Returns: true if this is a list 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

Returns: true if the type is namespace-sensitive

isUnionType

public boolean isUnionType()
Test whether this Simple Type is a union type

Returns: true if this is a union type

validateContent

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

Returns: null if validation succeeds; return a ValidationException 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
