Use <T> with Class <T> clazz, T instance, to require it actually satisfies the class its providing for.

I had this and it didn't work. when I want to pass the plugins class, I can't cast to it, thus throwing a compiler error. https://i.imgur.com/ynHskze.png

Same as above for <T>, but just make this registerDependency, since its a different signature

Not necessary with <T> restrictions
| throw new IllegalArgumentException(instance.getClass().getName() + " isn't a subclass of " + clazz.getName() + "!"); | ||
| } | ||
| if(dependencies.containsRow(clazz) && dependencies.containsColumn(key)){ | ||
| throw new IllegalStateException("There is already an instance of " + clazz.getName() + " with the key " + key + " registered!"); |

Not sure we should throw, but just let it overwrite, maybe return old, like a typical put operation.

I think also more descriptive "injectDependencies"
| Map<String, Object> resolveContexts(CommandIssuer sender, List<String> args, int argLimit) throws InvalidCommandArgument { | ||
| args = Lists.newArrayList(args); | ||
| String[] origArgs = args.toArray(new String[args.size()]); | ||
| String[] origArgs = args.toArray(new String[0]); |
| throw new InvalidCommandArgument(false); | ||
| } | ||
| return players.toArray(new OnlinePlayer[players.size()]); | ||
| return players.toArray(new OnlinePlayer[0]); |
|
if some bungee or sponge ppl could suggest default dependencies or the platform that would be great. |
| try { | ||
| field.setAccessible(true); | ||
| field.set(baseCommand, object); | ||
| field.setAccessible(false); |

Don't know if theres a reason to set this to false? what if it was already accessible before.

If getDeclaredFields is the one that only includes its own fields, then switch to the other. we want to include parent class fields too, but I'm not at a java doc atm.

when we don't use getDeclaredFields, we can't inject private fields. do we want to just iterate over both?

Remove the PluginContainer one since per @kashike its not the same thing.
aikar
changed the title
also ran some intellij inspections.
