public final class AnyURIValue
extends StringValue

An XPath value of type xs:anyURI.

This is implemented as a subtype of StringValue even though xs:anyURI is not a subtype of xs:string in the XPath type hierarchy. This enables type promotion from URI to String to happen automatically in most cases where it is appropriate.

This implementation of xs:anyURI allows any string to be contained in the value space. To check that the URI is valid according to some set of syntax rules, the caller should invoke a StandardURIChecker before constructing the AnyURIValue.

Field Detail

EMPTY_URI

public static final AnyURIValue EMPTY_URI

Constructor Detail

AnyURIValue

public AnyURIValue(CharSequence value)

Constructor

Parameters:

value - the String value. Null is taken as equivalent to "". This constructor does not check that the value is a valid anyURI instance. It does however perform whitespace normalization.

AnyURIValue

public AnyURIValue(CharSequence value,
           AtomicType type)

Constructor for a user-defined subtype of anyURI

Parameters:

value - the String value. Null is taken as equivalent to "".

type - a user-defined subtype of anyURI. It is the caller's responsibility to ensure that this is actually a subtype of anyURI, and that the value conforms to the definition of this type.

Method Detail

copyAsSubType

public AtomicValue copyAsSubType(AtomicType typeLabel)

Create a copy of this atomic value, with a different type label

Overrides:

copyAsSubType in class StringValue

Parameters:

typeLabel - the type label of the new copy. The caller is responsible for checking that the value actually conforms to this type.

Returns:

the copied value

getPrimitiveType

public BuiltInAtomicType getPrimitiveType()

Description copied from class: StringValue

Determine the primitive type of the value. This delivers the same answer as getItemType().getPrimitiveItemType(). The primitive types are the 19 primitive types of XML Schema, plus xs:integer, xs:dayTimeDuration and xs:yearMonthDuration, and xs:untypedAtomic. For external objects, the result is AnyAtomicType.

Overrides:

getPrimitiveType in class StringValue

Returns:

the primitive type

decode

public static String decode(String s)
