FlexScript Class - Variant

Variant

Description

A type that can hold either a number, a string, a treenode or an Array.

The Variant class is an essential type by which data is exchanged between various functionalities in FlexSim. As such, the Variant represents a "jack of all trades" that can hold several different types of data. It can be a number type, holding a number value. It can be a string type, holding text data. It can be a treenode type, holding a reference to a node in FlexSim's tree. It can be an Array type, holding an array of Variants. And finally, it can be a null variant meaning it is none of the other types.

Method/Property Forwarding

Since the Variant is just a flexible container for other data types, its methods and properties are just forwarders to the various methods and properties of the types that the Variant holds. For example, if you have a Variant holding a treenode, you can use all of the methods and properties on a treenode directly on the Variant without having to cast to a treenode with the as() keyword.

Variant node = param(1);
node.name = "Object1";
node.value = 5;

The only property that is exclusive to the Variant is type, which tells you what type of data is held by a Variant. All other properties and methods simply forward to the associated method or property of the held class. If the Variant does not hold the associated type, then calling the type's method will result in an exception. For example, if a Variant has a number, and you call the find() method on it, FlexScript will throw an exception.

Casting

Variant will cast to any of its target types without throwing an exception. If the Variant does not hold the target type, it will just give a null-or-similar result. This means a NULL treenode, empty string, empty Array, or 0.0 number.

Variant num = 1;
string asString = num; // empty string
Variant str = "Hello";
double asNum = str; // 0.0

To determine the type of data that is held by a Variant, use the type property, or use the is() keyword.

Variants as Objects

If a variant holds a treenode with Object data, it can access Object properties and methods. However, the type property is simply a treenode type. In order to test if a Variant holds an Object node, you can use the is() keyword:

Variant obj = param(1);
if (obj.is(Object)) {
	obj.location = Vec3(1, 2, 3);
}
Variants as Arrays

The Variant implements special logic associated with arrays in that you can treat a Variant like an Array even if it does not hold array data. If a Variant holds, for example, a string, you can treat the Variant as if it were a 1-length Array with a string as its first element.

Variant val = "Hello";
int len = val.length; // len = 1
return val[len]; // returns "Hello";

Also, if you cast a Variant into a non-array type, and the Variant is in fact an Array, the cast operation will return the first element of the array. Thus you can even treat an Array Variant as a non-array type.

Variant myArray = ["Hello", "World"];
string myString = myArray;
return myString; // returns "Hello"

These capabilities are especially useful in Process Flow, where you are often dealing with label values that may or may not contain array data, but you want to interface with those data in a consistent manner.

Null Values

To check if a Variant is null you can compare the value with the special keyword nullvar or compare its type with the VAR_TYPE_NULL macro.

Variant val;
val == nullvar //true
val.type == VAR_TYPE_NULL // true

Where this gets more complicated is when dealing with treenode type Variants returned by other properies. See the discussion of treenode null values.

Other data types do not have null types but have an empty type that corresponds to that type:

string emptyString = "";
int emptyInt = 0;
double emptyDouble = 0.0;
Array emptyArray = [];
