net.sf.saxon.value.UntypedAtomicValue
| UntypedAtomicValue | | public class UntypedAtomicValue extends StringValue (Code) | | 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.
|
| UntypedAtomicValue | | public UntypedAtomicValue(CharSequence value)(Code) | | Constructor
Parameters:
value - the String value. Null is taken as equivalent to "". |
| compareTo | | public int compareTo(Object other, Comparator collator, XPathContext context)(Code) | | 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.
-1 if the this value is less than the other, 0 if they are equal, +1 if thisvalue is greater. |
| getItemType | | public ItemType getItemType(TypeHierarchy th)(Code) | | Return the type of the expression
Type.UNTYPED_ATOMIC (always)
Parameters:
th - |
| schemaEquals | | public boolean schemaEquals(Value obj)(Code) | | Compare two values for equality. This supports identity constraints in XML Schema,
which allow list-valued elements and attributes to participate in key and uniqueness constraints.
This method returns false if any error occurs during the comparison, or if any of the items
in either sequence is a node rather than an atomic value. The default implementation of
schemaEquals() is the same as equals(), but subclasses can override this.
