PK_comparison_t

typedef int PK_comparison_t;


Specific Errors:
PK_ERROR_invalid_object      If constraint.interval.value[0] is greater than
                             constraint.interval.value[1].

Used in:

PK_double_constraint_t

This datatype allows the user to supply an interval and to test when given
a number (d) whether the constraint is true or false.  It has the following
values:

PK_comparison_always_c       true
PK_comparison_less_c         d <= constraint.interval.value[0]
PK_comparison_equal_c        d = constraint.interval.value[0]
PK_comparison_greater_c      d >= constraint.interval.value[1]
PK_comparison_between_c      d >= constraint.interval.value[0] &&
                             d <= constraint.interval.value[1]
PK_comparison_outside_c      d <= constraint.interval.value[0] ||
                             d >= constraint.interval.value[1]
PK_comparison_never_c        false
