CompoundTag
List tags represent NBT map-like data structure (key-value pairs). it's values may be of any type, so check the type before calling the appropriate getter.
constructor
Creates a new compound tag.
Returns CompoundTag
clear
Removes all the tags from the compound tags.
Returns void
contains
Parameters
key: string
Returns boolean
trueif specified key exists in compound tag.
containsValueOfType
Parameters
key: string
key to verify for the type
type: number
tag type to verify for, one of the ENbtDataType constants
Returns boolean
trueif specified key exists in compound tag and it's value is of specified type.
getAllKeys
Returns Array<string>
Java-array containing all the keys of the compound tag.
getByte
Parameters
key: string
Returns number
NBT tag of byte type by it's key.
getCompoundTag
Parameters
key: string
Returns CompoundTag
NBT tag of compound type by it's key. Note that a copy of existing compound tag is created so you cannot edit it directly. Use setCompoundTag method to apply changes or use getCompoundTagNoClone to edit it directly.

NBT (Named Binary Tag) is a tag based binary format designed to carry large amounts of binary data with smaller amounts of additional data. You can get or set nbt tags of entities, native tile entities (such as chests or beacons) and items. To get more information about these data structures, see page.
