public class UntypedAtomicValue extends StringValue
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.

copyAsSubType
public AtomicValue copyAsSubType(AtomicType typeLabel)
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
public BuiltInAtomicType 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
-
compareTo
public int compareTo(AtomicValue other, StringCollator collator, XPathContext context)
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.- Parameters:
other
- the value to compare this value withcollator
- the collation to be used for comparing stringscontext
- the XPath dynamic context- Returns:
- -1 if the this value is less than the other, 0 if they are equal, +1 if this value is greater.
- Throws:
java.lang.ClassCastException
- if the value cannot be cast to the type of the other operand
