Accessing Data

Accessing data can't be easier

The API was designed mainly to perform great while providing an easy and accessible approach to persistent data containers found in entities, blocks, etc.

Accessing the data:

Using the class: DataRegistry, you can easily access an item's, a player's or a block's persistent data.

The method used to access persistent data is:

@OverridepublicvoidonEnable() {
PersistentDataAPIapi = newPersistentDataAPI(this);
DataRegistrydata = api.getDataRegistry(player/item/blockobject);
}

After accessing an object's Dataregistry, we can use some methods:

Method	Parameters	Exceptions thrown	Description
registerData()	AbstractPersistentData / dataName, dataValue	DataException if data already exists	Registers a new data That doesn't exist
unregisterData()	AbstractPersistentData / dataName	DataException if data doesn't exist	Deletes a registered data
setData()	AbstractPersistentData / dataName, dataValue	none	Changes existing data's value. If data doesn't exist, it will create it
getData()	AbstractPersistentData / dataName	DataException if data doesn't exist	Returns the value of the requested data
getAll()	none	none	Returns all keys and values of the given object's data container, in a HashMap
getKeys()	none	none	Returns all keys of the given object's container in a Set
getDataAsBytes()	AbstractPersistentData / dataName	DataException if data doesn't exist	Returns the data serialized to bytes (as an array of bytes)
dataExist()	AbstractPersistentData / dataName	none	Returns true if the requested data exists, false otherwise
