Interface PqIntList

public interface PqIntList
Specialized list interface for INT32 values.

Provides primitive iteration without boxing overhead. 

PqIntList scores = row.getIntList("scores");
for (var it = scores.iterator(); it.hasNext(); ) {
    int score = it.nextInt();
}

// Or with forEach:
scores.forEach(score -> System.out.println(score));
