Lib Block Attributes

Changes:

• Added "lba.misc.OpenWrapper", which is meant to be the opposite of Convertible.
  • This is used in cases where an object really is a "simple wrapper" from one type to another
  • This has a single method: "Object getWrapped()".
    • Note that this may return null if an implementation can't expose the inner object without also exposing more details than they wish.
  • All of LBA's base wrapper implementations implement this:
    • GroupedItemInvViewFixedWrapper (returned by FixedItemInvView.getGroupedInv())
    • GroupedFluidInvViewFixedWrapper (returned by FixedFluidInvView.getGroupedInv())
    • FixedInventoryViewVanillaWrapper (turns a vanilla Inventory into an LBA FixedItemInvView)
    • InventoryFixedWrapper (turns an LBA FixedItemInv into a vanilla Inventory)
  • None of LBA's mod-compat implementations implement this.
• Added "lba.misc.Combined", which is meant to be the opposite of AttributeCombiner.
  • This is used in cases where an object is a "simpler combiner" of a list of objects (of the same type)
  • This has two methods:
    • "int getSubObjectCount()": Returns the number of objects that this combines.
    • "Object getSubObject(int index)": Returns the sub-object at that particular index.
      • Unlike "OpenWrapper" this must not return null, unless the index is invalid.
      • However getSubObjectCount() may return 0, or -1 if the sub-objects cannot be exposed normally.
  • There's also a new abstract class to make implementing these simpler: "lba.misc.AbstractCombined".
  • All of LBA's base combined implementations implement this.
