GetObjOrNull()

OutputVar := MfNull.GetObjOrNull(obj)

GetObjOrNull(obj)

Checks to see if an object is null and returns obj if not null; Otherwise MfNull.Null

Parameters

obj

The Object or var to check to see if it is Null

Returns

If obj is null then MfNull.Null is returned. Otherwise the obj is returned.

Remarks

Static Method
Will always return an object, to check if null object is returned you could use MfObject.Equals() as show in the example below.

Example

intC := 0
While intC < 5
{
	varV := MfNull.GetObjOrNull(MyGetSomeValueMethod(intC))
	if (MfObject.Equals(varV, Mfnull.Null)) {
		MsgBox, 64, Null, This time the value is null
	}
	else {
		MsgBox, 64, Integer, % "This time the value is: " . varV.Value
	}
	intC++
}

MyGetSomeValueMethod(cnt) {
	if (Mod(cnt, 2)) {
		return null
	}
	else {
		return new MfInteger(cnt)
	}
}
