  - negotiationType
```
@Deprecated
public OkHttpChannelBuilder negotiationType(NegotiationType type)
```
    Deprecated. use usePlaintext() or useTransportSecurity() instead.
    
    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
  - keepAliveTime

public OkHttpChannelBuilder keepAliveTime(long keepAliveTime,

public OkHttpChannelBuilder flowControlWindow(int flowControlWindow)

  - sslSocketFactory
```
public OkHttpChannelBuilder sslSocketFactory(SSLSocketFactory factory)
```
    Override the default SSLSocketFactory and enable TLS negotiation.
  - hostnameVerifier
```
public OkHttpChannelBuilder hostnameVerifier(@Nullable
                                             HostnameVerifier hostnameVerifier)
```
    Set the hostname verifier to use when using TLS negotiation. The hostnameVerifier is only used if using TLS negotiation. If the hostname verifier is not set, a default hostname verifier is used.
    Be careful when setting a custom hostname verifier! By setting a non-null value, you are replacing all default verification behavior. If the hostname verifier you supply does not effectively supply the same checks, you may be removing the security assurances that TLS aims to provide.
    
    This method should not be used to avoid hostname verification, even during testing, since AbstractManagedChannelImplBuilder.overrideAuthority(java.lang.String) is a safer alternative as it does not disable any security checks.
    
    Returns:
    
    this

    1.6.0

  - connectionSpec
```
public OkHttpChannelBuilder connectionSpec(com.squareup.okhttp.ConnectionSpec connectionSpec)
```
    For secure connection, provides a ConnectionSpec to specify Cipher suite and TLS versions.
    By default a modern, HTTP/2-compatible spec will be used.
    This method is only used when building a secure connection. For plaintext connection, use usePlaintext() instead.
    
    Throws:
    
    IllegalArgumentException - If connectionSpec is not with TLS
  - usePlaintext
```
public OkHttpChannelBuilder usePlaintext()
```
    Sets the negotiation type for the HTTP/2 connection to plaintext.
    
    Overrides:
    
    usePlaintext in class io.grpc.internal.AbstractManagedChannelImplBuilder<OkHttpChannelBuilder>
  - useTransportSecurity
```
public OkHttpChannelBuilder useTransportSecurity()
```
    Sets the negotiation type for the HTTP/2 connection to TLS (this is the default).
    With TLS 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(SSLSocketFactory) to override the socket factory used.
    
    Overrides:
    
    useTransportSecurity in class io.grpc.internal.AbstractManagedChannelImplBuilder<OkHttpChannelBuilder>
  - scheduledExecutorService
```
public OkHttpChannelBuilder scheduledExecutorService(ScheduledExecutorService scheduledExecutorService)
```
    Provides a custom scheduled executor service.
    It's an optional parameter. If the user has not provided a scheduled executor service when the channel is built, the builder will use a static cached thread pool.
    
    Returns:
    
    this
    
    Since:
    
    1.11.0
  - maxInboundMetadataSize
```
public OkHttpChannelBuilder maxInboundMetadataSize(int bytes)
```
    Sets the maximum size of metadata allowed to be received. Integer.MAX_VALUE disables the enforcement. Defaults to no limit (Integer.MAX_VALUE).
    The implementation does not currently limit memory usage; this value is checked only after the metadata is decoded from the wire. It does prevent large metadata from being passed to the application.
    
    Overrides:
    
    maxInboundMetadataSize in class io.grpc.internal.AbstractManagedChannelImplBuilder<OkHttpChannelBuilder>
    
    Parameters:
    
    bytes - the maximum size of received metadata
    
    Returns:
    
    this
    
    Throws:
    
    IllegalArgumentException - if bytes is non-positive
    
    Since:
    
    1.17.0
  - maxInboundMessageSize
```
public OkHttpChannelBuilder maxInboundMessageSize(int max)
```
    Sets the maximum message size allowed for a single gRPC frame. If an inbound messages larger than this limit is received it will not be processed and the RPC will fail with RESOURCE_EXHAUSTED.
    
    Overrides:
