Class GatewayGrpc.GatewayImplBase

java.lang.Object

org.hyperledger.fabric.protos.gateway.GatewayGrpc.GatewayImplBase

All Implemented Interfaces:

io.grpc.BindableService

Enclosing class:

GatewayGrpc

public abstract static class GatewayGrpc.GatewayImplBase
extends Object
implements io.grpc.BindableService

 The Gateway API for evaluating and submitting transactions via the gateway.
 Transaction evaluation (query) requires the invocation of the Evaluate service
 Transaction submission (ledger updates) is a two step process invoking Endorse
 followed by Submit. A third step, invoking CommitStatus, is required if the
 clients wish to wait for a Transaction to be committed.
 The proposal and transaction must be signed by the client before each step.

Method Summary

Modifier and Type	Method and Description
io.grpc.ServerServiceDefinition	bindService()
void	chaincodeEvents(SignedChaincodeEventsRequest request, io.grpc.stub.StreamObserver<ChaincodeEventsResponse> responseObserver) The ChaincodeEvents service supplies a stream of responses, each containing all the events emitted by the requested chaincode for a specific block.
void	commitStatus(SignedCommitStatusRequest request, io.grpc.stub.StreamObserver<CommitStatusResponse> responseObserver) The CommitStatus service will indicate whether a prepared transaction previously submitted to the Submit service has been committed.
void	endorse(EndorseRequest request, io.grpc.stub.StreamObserver<EndorseResponse> responseObserver) The Endorse service passes a proposed transaction to the gateway in order to obtain sufficient endorsement.
void	evaluate(EvaluateRequest request, io.grpc.stub.StreamObserver<EvaluateResponse> responseObserver) The Evaluate service passes a proposed transaction to the gateway in order to invoke the transaction function and return the result to the client.
void	submit(SubmitRequest request, io.grpc.stub.StreamObserver<SubmitResponse> responseObserver) The Submit service will process the prepared transaction returned from Endorse service once it has been signed by the client.

Method Detail

endorse

public void endorse(EndorseRequest request,
                    io.grpc.stub.StreamObserver<EndorseResponse> responseObserver)

 The Endorse service passes a proposed transaction to the gateway in order to
 obtain sufficient endorsement.
 The gateway will determine the endorsement plan for the requested chaincode and
 forward to the appropriate peers for endorsement. It will return to the client a
 prepared transaction in the form of an Envelope message as defined
 in common/common.proto. The client must sign the contents of this envelope
 before invoking the Submit service.
 

submit

public void submit(SubmitRequest request,
                   io.grpc.stub.StreamObserver<SubmitResponse> responseObserver)

 The Submit service will process the prepared transaction returned from Endorse service
 once it has been signed by the client. It will wait for the transaction to be submitted to the
 ordering service but the client must invoke the CommitStatus service to wait for the transaction
 to be committed.
 

commitStatus

public void commitStatus(SignedCommitStatusRequest request,
                         io.grpc.stub.StreamObserver<CommitStatusResponse> responseObserver)

 The CommitStatus service will indicate whether a prepared transaction previously submitted to
 the Submit service has been committed. It will wait for the commit to occur if it hasn’t already
 committed.
 

evaluate

public void evaluate(EvaluateRequest request,
                     io.grpc.stub.StreamObserver<EvaluateResponse> responseObserver)

 The Evaluate service passes a proposed transaction to the gateway in order to invoke the
 transaction function and return the result to the client. No ledger updates are made.
 The gateway will select an appropriate peer to query based on block height and load.
 

chaincodeEvents

public void chaincodeEvents(SignedChaincodeEventsRequest request,
                            io.grpc.stub.StreamObserver<ChaincodeEventsResponse> responseObserver)

 The ChaincodeEvents service supplies a stream of responses, each containing all the events emitted by the
 requested chaincode for a specific block. The streamed responses are ordered by ascending block number. Responses
 are only returned for blocks that contain the requested events, while blocks not containing any of the requested
 events are skipped.
