Class NbtCompound

java.lang.Object
net.minecraft.nbt.NbtCompound
All Implemented Interfaces:
NbtElement
public class NbtCompound extends Object implements NbtElement
Represents an NBT compound object. This mutable object holds unordered key-value pairs with distinct case-sensitive string keys. This can effectively be used like a HashMap<String, NbtElement>. Note that this does not implement Map. Its type is 0xa. To get the compound as a map, use
invalid reference 
#toMap()
.

There are two ways to use this compound; one is to create NBT instances yourself and use get(String) or put(String, NbtElement). Manual casting is required in this case. The other, easier way is to use methods with type names, such as getInt(String) or putInt(String, int). Where applicable, these methods return and accept Java types (e.g. int, long[]) instead of NbtElement subclasses. Note that there is no putCompound method, since you can just use the put method. These getters also have the advantage of providing type safety, because if type mismatch occurs or there is no such element in the compound, it returns the default value for that type instead of throwing or returning null.

    • getBoolean

      public boolean getBoolean(String key)
      Returns the boolean value stored with the key.
      Returns:
      the boolean value stored with the key
      Implementation Note:
      Since NBT does not have a boolean type, NbtByte is used instead. This method returns true for any values which, after casting to byte as described at getByte(String), is not 0. Since all non-numeric values become 0 during casting to bytes, this method returns false for those as well. This includes values often considered truthy in other languages, such as a non-empty string or list.
