Need more example in Transaction Insert and Query

[GulajavaMinistudio]

From this documentation, there are several transaction in ObjectBox
http://objectbox.io/documentation/transactions/

The class BoxStore offers the following methods to perform explicit transactions:
runInTx: Runs the given runnable inside a transaction.
runInReadTx: Runs the given runnable inside a read(-only) transaction. Unlike write transactions, multiple read transactions can run at the same time.
runInTxAsync: Runs the given Runnable as a transaction in a separate thread. Once the transaction completes the given callback is called (callback may be null).
callInTx: Like runInTx(Runnable), but allows returning a value and throwing an exception.

But I found little confused for runInTxAsync implementation. Any good example about how to implementation those transaction ?
