Method Detail

copyWithFlowControl

public static <V> void copyWithFlowControl(java.util.Iterator<V> source,
                                           CallStreamObserver<V> target)

Copy the values of an Iterator to the target CallStreamObserver while properly accounting for outbound flow-control. After calling this method, target should no longer be used.

For clients this method is safe to call inside ClientResponseObserver.beforeStart(io.grpc.stub.ClientCallStreamObserver<ReqT>), on servers it is safe to call inside the service method implementation.

Parameters:

source - of values expressed as an Iterator.

target - CallStreamObserver which accepts values from the source.

copyWithFlowControl

public static <V> void copyWithFlowControl(java.lang.Iterable<V> source,
                                           CallStreamObserver<V> target)

Copy the values of an Iterable to the target CallStreamObserver while properly accounting for outbound flow-control. After calling this method, target should no longer be used.

For clients this method is safe to call inside ClientResponseObserver.beforeStart(io.grpc.stub.ClientCallStreamObserver<ReqT>), on servers it is safe to call inside the service method implementation.

Parameters:

source - of values expressed as an Iterable.

target - CallStreamObserver which accepts values from the source.
