ItemPredicate
Represents the predicate for an MCItemDefinition.
This predicate will match an item against either a specific MCItemDefinition or item tag (MCTag<T>), with the second taking precedence over the first. If this initial check succeeds, then the predicate may also verify additional item properties, such as its current amount, its damage, or internal NBT data via NBTPredicate. The predicate can also check the enchantments that are currently either applied to or stored onto the item via EnchantmentPredicates, or the potion effect that is currently present on the item, if any.
By default, any item will be able to pass the checks of this predicate.
Importing the class
It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import at the very top of the file.

ItemPredicate.withDataPredicate(builder as Consumer<NBTPredicate>) as ItemPredicate| Parameter | Type | Description |
|---|---|---|

Creates and adds a new EnchantmentPredicate to the list of predicates to match against the item’s enchantments.
The added predicate is simply added to the list. No validity checks are performed, meaning that there may be multiple predicates that target a single enchantment. In this case, they all need to match, thus they have to have compatible bounds.
Returns: This predicate for chaining.

Sets the maximum amount of items to max.
If the amount had already some bounds specified, then the maximum value of the bound will be overwritten with the
value specified in max. On the other hand, if the amount didn’t have any bounds set, the maximum is
set, leaving the lower end unbounded.
The maximum value is inclusive, meaning that a value that is equal to max will pass the check.
