Constructor Detail

BindingSetComparator

public BindingSetComparator(ISortOrder<E>[] sortOrder,
                    Comparator<E> valueComparator)

Parameters:

sortOrder - The sort order to be imposed. While the ISortOrder is defined in terms of IValueExpressions, any IValueExpressions MUST be either bare variables or constants or be IBinds where the nested IValueExpression has been computed and bound on the solutions to be compared by the caller.

valueComparator - The comparator used on the values extracted from the IBindingSets.
