net.sf.saxon.value
Class AnyURIValue
java.lang.Object
net.sf.saxon.value.Value
net.sf.saxon.value.AtomicValue
net.sf.saxon.value.StringValue
net.sf.saxon.value.AnyURIValue
- All Implemented Interfaces:
- Expression, Item, java.io.Serializable, ValueRepresentation
- 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.

EMPTY_URI
public static final AnyURIValue EMPTY_URI
AnyURIValue
public AnyURIValue(java.lang.CharSequence value)
- Constructor
- Parameters:
value
- the String value. Null is taken as equivalent to "".
convertPrimitive
public AtomicValue convertPrimitive(BuiltInAtomicType requiredType,
boolean validate)
- Convert to target data type
- Overrides:
convertPrimitive
in class StringValue
- Parameters:
requiredType
- integer code representing the item type requiredvalidate
- true if validation is required. If set to false, the caller guarantees that
the value is valid for the target data type, and that further validation is therefore not required.
Note that a validation failure may be reported even if validation was not requested.
- Returns:
- the result of the conversion, or an ErrorValue
getItemType
public ItemType getItemType()
- Return the type of the expression
- Specified by:
getItemType
in interface Expression
- Overrides:
getItemType
in class StringValue
- Returns:
- Type.ANY_URI_TYPE (always)
equals
public boolean equals(java.lang.Object other)
- 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.)
- Overrides:
equals
in class StringValue
- Throws:
java.lang.ClassCastException
- if the values are not comparable
effectiveBooleanValue
public boolean effectiveBooleanValue(XPathContext context)
throws XPathException
- Get the effective boolean value of the value
- Specified by:
effectiveBooleanValue
in interface Expression
- Overrides:
effectiveBooleanValue
in class StringValue
- Parameters:
context
- the evaluation context (not used in this implementation)
- Returns:
- true, unless the value is boolean false, numeric zero, or
zero-length string
- Throws:
XPathException
convertToJava
public java.lang.Object convertToJava(java.lang.Class target,
XPathContext context)
throws XPathException
- Convert to Java object (for passing to external functions)
- Overrides:
convertToJava
in class StringValue
- Parameters:
target
- the Java class to which conversion is required
- Returns:
- the result of the conversion
- Throws:
XPathException
- if conversion to this target type is not possible
