Method Details

builder

static GrpcExceptionHandlerFunctionBuilder builder()

Returns a newly created GrpcExceptionHandlerFunctionBuilder.

apply

@Nullable
@Nullable io.grpc.Status apply(RequestContext ctx,
 Throwable cause,
 io.grpc.Metadata metadata)

Maps the specified Throwable to a gRPC Status, and mutates the specified Metadata. If null is returned, the built-in mapping rule is used by default.

orElse

default GrpcExceptionHandlerFunction orElse(GrpcExceptionHandlerFunction next)

Returns a GrpcExceptionHandlerFunction that returns the result of this function when this function returns non null result, in which case the specified function isn't executed. when this function returns null, returns a GrpcExceptionHandlerFunction that the result of the specified GrpcExceptionHandlerFunction.
