areEqual(o1:*, o2:*):Boolean [static]
Checks if objects are equal. | EquatableUtil | ||
| EquatableUtil | () | Constructor |
public function EquatableUtil()NumberUtil is a static class and shouldn't be instantiated.
IllegalOperationError — NumberUtil is a static class and shouldn't be instantiated.

| areEqual | () | method |
public static function areEqual(o1:*, o2:*):BooleanChecks if objects are equal.
First thi method compare objects using o1 == o2.
If it returns true then the method returns true.
Otherwise it will be checked if both objects implement org.as3coreaddendum.system.IEquatable interface and then use o1.equals(o2).
Parameters
o1:* — a Number object to evaluate.
| |
o2:* |
Boolean — true if the value is NaN (not a number) and false otherwise.
