test

Description copied from interface: Predicate

Test based on the specific input row.

Specified by:

test in interface Predicate

Returns:

return true when hit, false when not hit.

test

Description copied from interface: Predicate

Test based on the statistical information to determine whether a hit is possible.

Specified by:
