DISCLAIMER: These notes are from the defunct k8 project which precedes SquirrelJME. The notes for SquirrelJME start on 2016/02/26! The k8 project was effectively a Java SE 8 operating system and as such all of the notes are in the context of that scope. That project is no longer my goal as SquirrelJME is the spiritual successor to it.
Previously for WormStore I used the class type of an enumeration instead of using the actual Enum values so that they are not duplicated many in memory. However this complicates and probably does not save much although the enumeration list of valid elements is only stored for each unique VClass. So the little loss of memory is not a grave concern since it is only used in the echelon system. In the real kernel classes will not use the echelon system to represent class information as that said information exists in the binary format of the converted class.
Seems my WormStore code will need to be rethinked, I wish I really had access to default interface methods because I cannot invoke public methods that exist only in specific enumerations.
After not thinking about it and playing Zelda instead, while I was preparing to make food I realized that I am over complicating things. Instead of calling methods in the seemingly package private inner classes, I will instead invoke a static class or a protected inherited class member of WormStore. I will then pass the RWStruct along with the Enum and the expected value. The sub implementation can then do whatever such as invoking hidden members of the enumerations. I can either do protected abstract or a public static. Protected abstract could work although RWStruct is not classed off the sub class so that cannot work. Therefor public static must be done (cannot be private or protected because it is invisible), the class will be checked for that method and use that instead for verification purposes. I will have to start each static method with "ws" so that calls are avoided. If a read-only WormStore is passed to it and it tries modifying it anyway, it will fail. 2014/07/21 -- The following was moved from the k8 LaTeX file and placed here instead. Belayed String intern()
Normally in the implementation of the virtual machine there will be a string pool. This string pool contains many strings, however the string pool is only used to reduce string usage, and in most loading cases is not used much except by the class loader and such. Rather than adding unique strings to the pool when they are created, unique values will only be done at the time of intern(). This means that the first intern of a string value will return the same reference and latern intern() of those strings will return future references of the first call to intern. The string pool will then contain only soft references of intern strings. This way they are collected if nothing ever references them again.
