Method Detail

appendClientFilter

public GrpcClientFactory<Client,BlockingClient,Filter,FilterableClient,FilterFactory> appendClientFilter(FilterFactory before)

Appends the passed FilterFactory to this factory.

The order of execution of these filters are in order of append. If 3 filters are added as follows:

     filter1.append(filter2).append(filter3)
 

making a request to a client wrapped by this filter chain the order of invocation of these filters will be:

     filter1 => filter2 => filter3 => client
 

Parameters:

before - the factory to apply before this factory is applied

Returns:

this

appendClientFilterFactory

protected abstract FilterFactory appendClientFilterFactory(FilterFactory existing,
                                                           FilterFactory append)

Appends the passed FilterFactory to this client factory.

Parameters:

existing - Existing FilterFactory.

append - FilterFactory to append to existing.

Returns:

a composed factory that first applies the before factory and then applies existing factory

newClient

protected abstract Client newClient(GrpcClientCallFactory clientCallFactory)

Create a new client that follows the specified gRPC Client contract using the passed GrpcClientCallFactory.

Parameters:

clientCallFactory - GrpcClientCallFactory to use for creating client calls. The returned Client should own the lifecycle of this factory.

Returns:

A new gRPC client following the specified gRPC Client contract.

newFilter

protected abstract Filter newFilter(Client client,
                                    FilterFactory filterFactory)

Create a new Filter using the passed Client and FilterFactory.

Parameters:

client - Client to use for creating a Filter through the FilterFactory.

filterFactory - FilterFactory

Returns:

A Filter filtering the passed Client.

newClient

protected abstract Client newClient(FilterableClient filterableClient)

Create a new Client using the passed FilterableClient.

Parameters:

filterableClient - FilterableClient to create a Client from.

Returns:

A new gRPC client following the specified gRPC Client contract.

newBlockingClient

protected abstract BlockingClient newBlockingClient(GrpcClientCallFactory clientCallFactory)

Create a new client that follows the specified gRPC BlockingClient contract using the passed GrpcClientCallFactory.

Parameters:

clientCallFactory - GrpcClientCallFactory to use for creating client calls. The returned Client should own the lifecycle of this factory.

Returns:

A new gRPC client following the specified gRPC BlockingClient contract.
