Enclosing class:
UtilServiceGrpc
public static final class UtilServiceGrpc.UtilServiceFutureStub extends io.grpc.stub.AbstractFutureStub<UtilServiceGrpc.UtilServiceFutureStub>
A stub to allow clients to do ListenableFuture-style rpc calls to service UtilService. 

 The Utility Service provides a pseudo-random number generator.
 The single gRPC call defined for this service simply reports a single
 pseudo-random number in the transaction record. That value may either
 be a 32-bit integer within a requested range, or a 384-bit byte array.
 ### Block Stream Effects
 The requested value is reported exclusively in a `UtilPrngOutput` message.

    • atomicBatch

      public com.google.common.util.concurrent.ListenableFuture<TransactionResponse> atomicBatch(Transaction request)
      
 Execute a batch of transactions atomically.
 <p>
