Method Details

newClientTransport

ConnectionClientTransport newClientTransport(SocketAddress serverAddress,
 ClientTransportFactory.ClientTransportOptions options,
 ChannelLogger channelLogger)

Creates an unstarted transport for exclusive use. Ownership of options is passed to the callee; the caller should not reuse or read from the options after this method is called.

Parameters:

serverAddress - the address that the transport is connected to

options - additional configuration

channelLogger - logger for the transport.

getScheduledExecutorService

ScheduledExecutorService getScheduledExecutorService()

Returns an executor for scheduling provided by the transport. The service should be configured to allow cancelled scheduled runnables to be GCed.

The executor should not be used after the factory has been closed. The caller should ensure any outstanding tasks are cancelled before the factory is closed. However, it is a known issue that ClientCallImpl may use this executor after close, so implementations should not go out of their way to prevent usage.

swapChannelCredentials

@CheckReturnValue
@Nullable
ClientTransportFactory.SwapChannelCredentialsResult swapChannelCredentials(ChannelCredentials channelCreds)

Swaps to a new ChannelCredentials with all other settings unchanged. Returns null if the ChannelCredentials is not supported by the current ClientTransportFactory settings.

close

void close()

Releases any resources.

After this method has been called, it's no longer valid to call newClientTransport(java.net.SocketAddress, io.grpc.internal.ClientTransportFactory.ClientTransportOptions, io.grpc.ChannelLogger). No guarantees about thread-safety are made.

getSupportedSocketAddressTypes

Collection<Class<? extends SocketAddress>> getSupportedSocketAddressTypes()

Returns the SocketAddress types this transport supports.
