In an enum class two synthetic methods are created in the Bystecode. * values(): returns an array with all values, uses System.arraycopy * valueOf(String name): returns the value with the name name.

With this the mark phase must not be interrupted, while sweeping can be done piecewise. Lists with free blocks are kept by the class Heap. Adresses of free blocks are simple integer values. text/html 2022-12-20T11:27:12+00:00 Anonymous (anonymous@undisclosed.example.com) https://deepjava.org/dev/rts/start?rev=1671532032&do=diff Runtime System (RTS) The Java standard library is very powerful and rich. However, as our target compiler puts its focus on efficiency we do not want to support the full library. Some of the base classes, notably java/lang/String, is implemented much more efficient than the standard library. This leads to a very small memory footprint.
