HelpModifiers class

Modifiers

static

  • modifies members of a class (variables, functions)
    • only affects the class, not on instances of the class

final

  • modifies variables (var, int, double)
    • must be assigned on init
    • shallow immutability: e.g., final collection members can be mutable, collection itself is immutable

const

  • modifies values and objects ([1,2,3], Point(2,3))
    • compile time constant: state can be determined at compile time and is then frozen (e.g., 1+2 is compile time const, DateTime.now() is not)
    • deep (transitive) immutability: e.g., const collection members are immutable, recursively
    • canonicalised values and objects: all assignments of the const value/object will refer to the same instance
