Package tenapull.util

Class Var<T>

java.lang.Object
tenapull.util.Var<T>
Type Parameters:
T - the type being wrapped
Direct Known Subclasses:
Var.String
public class Var<T>
extends java.lang.Object
Wraps a value of any type (T). Used mainly so that a lambda may mutate the value of a variable in the outer scope, because lambdas require that an outer variable be 'final or effectively final' if it is to be accessible from within the lambda. An instance of var satisfies this requirement while allowing its 'value' property to be mutated.

Also includes static-inner-class wrappers of each primitive type
