value_data_t const *  rhs 
)
static

Call the correct data comparison function for the condition.

Deals with regular expression comparisons, virtual attribute comparisons, and data comparisons.

Returns
  • -1 on failure.
  • 0 for "no match".
  • 1 for "match".

Convert both operands to the same type.

If casting is successful, we call cond_cmp_values to do the comparison

Returns
  • -1 on failure.
  • 0 for "no match".
  • 1 for "match".
