An abort message.

Returns

An error is returned with the associated abort message.

Examples

The query below is a single transaction with three statements. The first statement creates a class, the second statement adds an instance to the class, and the third statement aborts the transaction. Due to the transaction being terminated by the Abort call, neither the creation of the class nor the addition of the instance is present in the database.

System.out.println(client.query(
     Arr(
       CreateClass(Obj("name", Value("cars"))),
       Create(
            Class("cars"),
            Obj( "data", Obj( "name", Value("Ford") ) )),
       Abort("Reset Transaction")
     )
).get());

ERROR java.util.concurrent.ExecutionException:
         com.faunadb.client.errors.BadRequestException: transaction aborted: Reset Transaction
