What Is The Difference Between Sealed Class And Dynamic Classes In Flex?

Answer»

Classes are sealed by default, i.e. properties cannot be added dynamically at runtime.

  • Dynamic classes can add additional dynamic properties at runtime; sealed classes cannot.
  • Sealed classes conserve MEMORY because no INTERNAL hash table is NEEDED to STORE dynamic properties, and the compiler can provide better ERROR feedback.
