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
-
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.- 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:
ClassCastException
- if the value cannot be cast to the type of the other operand
