This method implements a null value safe comparison of two objects. If the two given parameters are both null, the method returns true. If either parameter is null while the other is not null, the method returns false. In the other case, a first parameter's Object.equals(Object) method is called and the result is returned.

Parameters:

o1 - First object to be compared or null

o2 - Second object to be compared or null

Returns:

true iff both parameters are null or they equal accordingly to Object.equals(Object)
