About manager

Manager uses Optional for minimizing NullPointerException moments. If you don't know how Optional works in this page you gonna understand it.

Finding and getting the item

To get the CustomItem object you can use this:

CustomItemManager manager = CustomItemManager.getManager();
manager.customItem("ID").ifPresent((item) -> {
    // Some code
});
// OR
CustomItem item = manager.customItem("ID").orElse(null); // If you don't like lambda

If we talk about runtime object of custom items:

ItemStack item = // some item here
CustomItemManager manager = CustomItemManager.getManager();
manager.tryGetCustomItem(item).ifPresent((runtime) -> {
    // Code here
});
// OR
// If you don't like lambda
CustomItemRuntime runtime = manager.tryGetCustomItem(item).orElse(null);

Creating ItemStack

To create ItemStack we need CustomItem object and manager:

CustomItemManager manager = CustomItemManager.getManager();
manager.customItem("ID").ifPresent((item) -> {
    ItemStack itemStack = manager.createItem(item);
    // Code here
});
// OR
CustomItem item = manager.customItem("ID").orElse(null); // If you don't like lambda
if (item != null) {
    ItemStack itemStack = manager.createItem(item);
}

Checking if item is custom

CustomItemManager manager = CustomItemManager.getManager();
boolean check = manager.isCustomItem(itemStack); // recomended
// OR
boolean check = manager.tryGetCustomItem(itemStack).isPresent();

Register the item

CustomItemManager.getManager().register(new MyItem());
