You can compute the threshold ahead of time and reference it directly in
the filter function.
(Below are 2 examples, depending on whether you like lambdas or not)
final int threshold =computeThreshold(); temperatureStream.filter(new
FilterFunction<Integer>() {
@Override public boolean filter(Integer temperature) {
return temperature >threshold; }
});
final int threshold =computeThreshold(); temperatureStream.filter(temperature ->
temperature >threshold);

Hi everyone,
Suppose I have to compute a filter condition
Integer threshold = compute threshold();
If I:
temperatureStream.filter(new FilterFunction<temperature>() {
@Override
public boolean filter(Integer temperature) throws Exception {
Integer threshold = compute threshold();
return temperature > threshold
}
would this mean I have computed threshold over and over again, for
every new element in the stream?
my threshold does not changes once it computed. I don't want to
recompute it every time for new elements? is there way I can pass it
as a parameter to the filter function?
