Class TxReport

java.lang.Object

org.mozilla.mentat.TxReport

All Implemented Interfaces:

AutoCloseable

public class TxReport
extends Object

This class wraps a raw pointer than points to a Rust `TxReport` object.

The `TxReport` contains information about a successful Mentat transaction.

This information includes:

• `txId` - the identifier for the transaction.
• `txInstant` - the time that the transaction occured.
• a map of temporary identifiers provided in the transaction and the `Entid`s that they were mapped to.

Access an `Entid` for a temporary identifier that was provided in the transaction can be done through `entid(String:)`.

 TxReport report = mentat.transact("[[:db/add "a" :foo/boolean true]]");
 long aEntid = report.getEntidForTempId("a");
