    • getAsString

      @NotNull @NotNull String getAsString()
      Get this ItemMeta as an NBT string. If this ItemMeta does not have any NBT, then "{}" will be returned.

      This string should NEVER be relied upon as a serializable value. If serialization is desired, the ConfigurationSerializable API should be used instead.

      返回:
      the NBT string
    • getAsComponentString

      @NotNull @NotNull String getAsComponentString()
      Get this ItemMeta as a component-compliant string. If this ItemMeta does not contain any components, then "[]" will be returned.

      The result of this method should yield a string representing the components altered by this ItemMeta instance. When passed to ItemFactory.createItemStack(String) with a prepended item type, it will create an ItemStack that has an ItemMeta matching this ItemMeta instance exactly. Note that this method returns ONLY the components and cannot be passed to createItemStack() alone. An example may look something like this:

       ItemStack itemStack = // ... an item stack obtained from somewhere
       ItemMeta itemMeta = itemStack.getItemMeta();
      
       String components = itemMeta.getAsComponentString(); // example: "[minecraft:damage=53]"
       String itemTypeKey = itemStack.getType().getKey().toString(); // example: "minecraft:diamond_sword"
       String itemAsString = itemTypeKey + components; // results in: "minecraft:diamond_sword[minecraft:damage=53]"
      
       ItemStack recreatedItemStack = Bukkit.getItemFactory().createItemStack(itemAsString);
       assert itemStack.isSimilar(recreatedItemStack); // Should be true*
       

      *Components not represented or explicitly overridden by this ItemMeta instance will not be included in the resulting string and therefore may result in ItemStacks that do not match exactly. For example, if setDisplayName(String) is not set, then the custom name component will not be included. Or if this ItemMeta is a PotionMeta, it will not include any components related to lodestone compasses, banners, or books, etc., only components modifiable by a PotionMeta instance.

      This string should NEVER be relied upon as a serializable value. If serialization is desired, the ConfigurationSerializable API should be used instead.

      返回:
      the component-compliant string
    • getCustomTagContainer

      @NotNull @Deprecated(since="1.14") @NotNull CustomItemTagContainer getCustomTagContainer()

      原文: Returns a public custom tag container capable of storing tags on the item. Those tags will be sent to the client with all of their content, so the client is capable of reading them. This will result in the player seeing a NBT Tag notification on the item. These tags can also be modified by the client once in creative mode
