Enclosing class:
UtilServiceGrpc
public static final class UtilServiceGrpc.UtilServiceStub extends io.grpc.stub.AbstractAsyncStub<UtilServiceGrpc.UtilServiceStub>
A stub to allow clients to do asynchronous 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.

    • prng

      public void prng(Transaction request, io.grpc.stub.StreamObserver<TransactionResponse> responseObserver)
      
 Generate a pseudo-random value.
 <p>
 The request body MUST be a
 [UtilPrngTransactionBody](#proto.UtilPrngTransactionBody)

    • atomicBatch

      public void atomicBatch(Transaction request, io.grpc.stub.StreamObserver<TransactionResponse> responseObserver)
      
 Execute a batch of transactions atomically.
 <p>
 All transactions in the batch will be executed in order, and if any
 transaction fails, the entire batch will fail.
