| AnyURIValue | | final public class AnyURIValue extends StringValue (Code) | | 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. It is possible
to validate that the string is a "valid URI" in the sense of XML Schema Part 2 (which refers to the XLink
specification and to RFC 2396); however, this validation is optional, and is not carried out by default.
In particular, there is no constraint that namespace URIs, collation URIs, and the like should be valid
URIs. However, casting from strings to xs:anyURI does invoke validation.

| AnyURIValue | | public AnyURIValue(CharSequence value)(Code) | | Constructor
Parameters:
value - the String value. Null is taken as equivalent to "". |
| convertPrimitive | | public AtomicValue convertPrimitive(BuiltInAtomicType requiredType, boolean validate, XPathContext context)(Code) | | Convert to target data type
Parameters:
requiredType - integer code representing the item type required
Parameters:
context - the result of the conversion, or an ErrorValue |
| convertToJava | | public Object convertToJava(Class target, XPathContext context) throws XPathException(Code) | | Convert to Java object (for passing to external functions)
Parameters:
target - the Java class to which conversion is required the result of the conversion
throws:
XPathException - if conversion to this target type is not possible |
| effectiveBooleanValue | | public boolean effectiveBooleanValue(XPathContext context) throws XPathException(Code) | | Get the effective boolean value of the value
Parameters:
context - the evaluation context (not used in this implementation) true, unless the value is boolean false, numeric zero, orzero-length string |
| equals | | public boolean equals(Object other)(Code) | | Determine if two AnyURIValues are equal, according to XML Schema rules. (This method
is not used for XPath comparisons, which are always under the control of a collation.)
throws:
ClassCastException - if the values are not comparable |
| getItemType | | public ItemType getItemType(TypeHierarchy th)(Code) | | Return the type of the expression
Type.ANY_URI_TYPE (always)
Parameters:
th - |
| isValidURI | | public static boolean isValidURI(CharSequence value)(Code) | | Check whether a string consititutes a valid URI
