Constructor Detail

OkHttpChannelBuilder

protected OkHttpChannelBuilder(String host,
                               int port)

Method Detail

forAddress

public static OkHttpChannelBuilder forAddress(String host,
                                              int port)

Creates a new builder for the given server host and port.

forTarget

public static OkHttpChannelBuilder forTarget(String target)

Creates a new builder for the given target that will be resolved by NameResolver.

transportExecutor

public final OkHttpChannelBuilder transportExecutor(@Nullable
                                                    Executor transportExecutor)

Override the default executor necessary for internal transport use.

The channel does not take ownership of the given executor. It is the caller' responsibility to shutdown the executor when appropriate.

negotiationType

public final OkHttpChannelBuilder negotiationType(NegotiationType type)

Sets the negotiation type for the HTTP/2 connection.

If TLS is enabled a default SSLSocketFactory is created using the best Provider available and is NOT based on SSLSocketFactory.getDefault(). To more precisely control the TLS configuration call sslSocketFactory to override the socket factory used.

Default: TLS

enableKeepAlive

public final OkHttpChannelBuilder enableKeepAlive(boolean enable)

Enable keepalive with default delay and timeout.

enableKeepAlive

public final OkHttpChannelBuilder enableKeepAlive(boolean enable,
                                                  long keepAliveDelay,
                                                  TimeUnit delayUnit,
                                                  long keepAliveTimeout,
                                                  TimeUnit timeoutUnit)

Enable keepalive with custom delay and timeout.

sslSocketFactory

public final OkHttpChannelBuilder sslSocketFactory(SSLSocketFactory factory)

Override the default SSLSocketFactory and enable NegotiationType.TLS negotiation.

By default, when TLS is enabled, SSLSocketFactory.getDefault() will be used.

NegotiationType.TLS will be applied by calling this method.

connectionSpec

public final OkHttpChannelBuilder connectionSpec(ConnectionSpec connectionSpec)

For secure connection, provides a ConnectionSpec to specify Cipher suite and TLS versions.

By default DEFAULT_CONNECTION_SPEC will be used.

This method is only used when building a secure connection. For plaintext connection, use usePlaintext(boolean) instead.

Throws:

IllegalArgumentException - If connectionSpec is not with TLS

usePlaintext

public final OkHttpChannelBuilder usePlaintext(boolean skipNegotiation)

Equivalent to using negotiationType(NegotiationType) with PLAINTEXT.

Specified by:

usePlaintext in class ManagedChannelBuilder<OkHttpChannelBuilder>

buildTransportFactory

protected final io.grpc.internal.ClientTransportFactory buildTransportFactory()

Specified by:

buildTransportFactory in class io.grpc.internal.AbstractManagedChannelImplBuilder<OkHttpChannelBuilder>

getNameResolverParams

protected Attributes getNameResolverParams()

Overrides:
