hagersaleh commented on FLINK-1910:
-----------------------------------
the result should happen
(2,Customer#000000002,XSTf4&&NCwDVaWNe6tEgvwfmRchLXak,121.65,AUTOMOBILE)
problem in this line i pass value from linkedlist
c.getField(4).equals(values.get(0).toString()) &&
c.getField(2).equals(values.get(1).toString())
new FilterFunction<Customer>() {
@Override
public boolean filter(Customer c) {
return c.getField(4).equals(values.get(0).toString()) &&
c.getField(2).equals(values.get(1).toString()) ;
}
});
but when write the coding when pass value Direct result coding =
(2,Customer#000000002,XSTf4&&NCwDVaWNe6tEgvwfmRchLXak,121.65,AUTOMOBILE)
when pass value Direct
new FilterFunction<Customer>() {
@Override
public boolean filter(Customer c) {
return c.getField(4).equals("AUTOMOBILE") &&
c.getField(2).equals("XSTf4&&NCwDVaWNe6tEgvwfmRchLXak") ;
}
});
> why this code flink not reurn value when use variable in filter
