Method Details

sameValueAs

public static boolean sameValueAs(NodeValue nv1,
 NodeValue nv2)

Return true if the two NodeValues are known to be the same value return false if known to be different values, throw ExprEvalException otherwise

compareByValue

public static int compareByValue(NodeValue nv1,
 NodeValue nv2)

compareAlways

public static int compareAlways(NodeValue nv1,
 NodeValue nv2)

raise

public static void raise(ExprException ex)

compareWithOrdering

public static int compareWithOrdering(NodeValue nv1,
 NodeValue nv2)

The sort order is to apply the rules in the following order:

1. Order by value space
2. Within a value space, order by value (if possible)
3. Order by RDF term (syntax)
