return true when hit, false when not hit.

test

public boolean test(InternalRow row)

从接口复制的说明: Predicate

Test based on the specific input row.

指定者:

test 在接口中 Predicate

返回:

return true when hit, false when not hit.

test

public boolean test(long rowCount,
                    FieldStats[] fieldStats)

从接口复制的说明: Predicate

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

指定者:

test 在接口中 Predicate

返回:

return true is likely to hit (there may also be false positives), return false is absolutely not possible to hit.

negate

public Optional<Predicate> negate()

指定者:

negate 在接口中 Predicate

返回:

the negation predicate of this predicate if possible.

visit
