Need more example in Transaction Insert and Query
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 ?
I suppose looking at the implementation of BoxStore.runInTxAsync can clear things up for you? It's basically the same as runInTx
, except the Runnable
is submitted to a thread pool and you get a callback once the transaction is done.
Simple example:
boxStore.runInTxAsync(new Runnable() {
@Override
public void run() {
notesBox.put(note);
...
}
}, new TxCallback<Void>() {
@Override
public void txFinished(@Nullable Void result, @Nullable Throwable error) {
// transaction is done! do something?
}
});
We maybe could add examples for this. -ut
Thank you for response. Yes there's need addition in Documentation and Examples about every Transactions methods .
