Alessio Fabiani a écrit :
public boolean evaluate(Feature feature) {
Object value1 = eval( expression1, feature );
Object value2 = eval( expression2, feature );
if (value1 instanceof Long) {
value1 = new Integer(((Long)value1).intValue());
}
if (value2 instanceof Long) {
value2 = new Integer(((Long)value2).intValue());
}
return (value1 == null && value2 == null) ||
value1 != null && value1.equals( value2 );
}
Casting a long to an int before the comparaison may lead to inexact results if the long values
required more than 32 bits... A possible approach is to add the following check:
if (value1 instanceof Long) {
long v = ((Long)value1).longValue();
if (v >= Integer.MIN_VALUE && v <= Integer.MAX_VALUE) {
value1 = new Integer((int) v);
}
}
