test

public abstract boolean test(DataType type,
                             Object field,
                             List<Object> literals)

test

public abstract boolean test(DataType type,
                             long rowCount,
                             FieldStats fieldStats,
                             List<Object> literals)

negate

public abstract Optional<LeafFunction> negate()

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

visit

public abstract <T> T visit(FunctionVisitor<T> visitor,
                            FieldRef fieldRef,
                            List<Object> literals)
