An Untyped Atomic value. This inherits from StringValue for implementation convenience, even
though an untypedAtomic value is not a String in the data model type hierarchy.

Method Details

copyAsSubType
Create a copy of this atomic value, with a different type label- Overrides:
copyAsSubType
in classStringValue
- 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
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 classStringValue
- Returns:
- the primitive type
-
convertPrimitive
public ConversionResult convertPrimitive(BuiltInAtomicType requiredType, boolean validate, XPathContext context) Convert to target data type- Overrides:
convertPrimitive
in classStringValue
- Parameters:
requiredType
- type code of the required atomic typevalidate
- 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.context
- XPath dynamic context. Used only where the target type is one such as NCName whose definition is context-sensitive- Returns:
- the result of the conversion, if successful. If unsuccessful, the value returned will be a ValidationErrorValue. The caller must check for this condition. No exception is thrown, instead the exception will be encapsulated within the ErrorValue.
-
compareTo
Compare an untypedAtomic value with another value, using a given collator to perform any string comparisons. This works by converting the untypedAtomic value to the type of the other operand, which is the correct behavior for operators like "=" and "!=", but not for "eq" and "ne": in the latter case, the untypedAtomic value is converted to a string and this method is therefore not used.- Returns:
- -1 if the this value is less than the other, 0 if they are equal, +1 if this value is greater.
- Throws:
ClassCastException
- if the value cannot be cast to the type of the other operand
