Method Details

forAddress

public static ManagedChannelBuilder<?> forAddress(String name,
 int port)

forTarget

public static ManagedChannelBuilder<?> forTarget(String target)

directExecutor

public ManagedChannelImplBuilder directExecutor()

Description copied from class: ManagedChannelBuilder

Execute application code directly in the transport thread.

Depending on the underlying transport, using a direct executor may lead to substantial performance improvements. However, it also requires the application to not block under any circumstances.

Calling this method is semantically equivalent to calling ManagedChannelBuilder.executor(Executor) and passing in a direct executor. However, this is the preferred way as it may allow the transport to perform special optimizations.

Specified by:

directExecutor in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

executor

public ManagedChannelImplBuilder executor(Executor executor)

Description copied from class: ManagedChannelBuilder

Provides a custom executor.

It's an optional parameter. If the user has not provided an executor when the channel is built, the builder will use a static cached thread pool.

The channel won't take ownership of the given executor. It's caller's responsibility to shut down the executor when it's desired.

Specified by:

executor in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

offloadExecutor

public ManagedChannelImplBuilder offloadExecutor(Executor executor)

Description copied from class: ManagedChannelBuilder

Provides a custom executor that will be used for operations that block or are expensive, to avoid blocking asynchronous code paths. For example, DNS queries and OAuth token fetching over HTTP could use this executor.

It's an optional parameter. If the user has not provided an executor when the channel is built, the builder will use a static cached thread pool.

The channel won't take ownership of the given executor. It's caller's responsibility to shut down the executor when it's desired.

Overrides:

offloadExecutor in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

intercept

public ManagedChannelImplBuilder intercept(List<ClientInterceptor> interceptors)

Description copied from class: ManagedChannelBuilder

Adds interceptors that will be called before the channel performs its real work. This is functionally equivalent to using ClientInterceptors.intercept(Channel, List), but while still having access to the original ManagedChannel. Interceptors run in the reverse order in which they are added, just as with consecutive calls to ClientInterceptors.intercept().

Specified by:

intercept in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

intercept

public ManagedChannelImplBuilder intercept(ClientInterceptor... interceptors)

Description copied from class: ManagedChannelBuilder

Adds interceptors that will be called before the channel performs its real work. This is functionally equivalent to using ClientInterceptors.intercept(Channel, ClientInterceptor...), but while still having access to the original ManagedChannel. Interceptors run in the reverse order in which they are added, just as with consecutive calls to ClientInterceptors.intercept().

Specified by:

intercept in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

interceptWithTarget

protected ManagedChannelImplBuilder interceptWithTarget(ManagedChannelBuilder.InterceptorFactory factory)

Description copied from class: ManagedChannelBuilder

Internal-only: Adds a factory that will construct an interceptor based on the channel's target. This can be used to work around nameResolverFactory() changing the target string.

Overrides:

interceptWithTarget in class ManagedChannelBuilder<ManagedChannelImplBuilder>

addTransportFilter

public ManagedChannelImplBuilder addTransportFilter(ClientTransportFilter hook)

Description copied from class: ManagedChannelBuilder

Adds a ClientTransportFilter. The order of filters being added is the order they will be executed

Overrides:

addTransportFilter in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

nameResolverFactory

@Deprecated
public ManagedChannelImplBuilder nameResolverFactory(NameResolver.Factory resolverFactory)

Deprecated.

Description copied from class: ManagedChannelBuilder

Provides a custom NameResolver.Factory for the channel. If this method is not called, the builder will try the providers registered in the default NameResolverRegistry for the given target.

This method should rarely be used, as name resolvers should provide a NameResolverProvider and users rely on service loading to find implementations in the class path. That allows application's configuration to easily choose the name resolver via the 'target' string passed to ManagedChannelBuilder.forTarget(String).

Specified by:

nameResolverFactory in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

defaultLoadBalancingPolicy

public ManagedChannelImplBuilder defaultLoadBalancingPolicy(String policy)

Description copied from class: ManagedChannelBuilder

Sets the default load-balancing policy that will be used if the service config doesn't specify one. If not set, the default will be the "pick_first" policy.

Policy implementations are looked up in the default LoadBalancerRegistry.

This method is implemented by all stock channel builders that are shipped with gRPC, but may not be implemented by custom channel builders, in which case this method will throw.

Overrides:

defaultLoadBalancingPolicy in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

decompressorRegistry

public ManagedChannelImplBuilder decompressorRegistry(DecompressorRegistry registry)

Description copied from class: ManagedChannelBuilder

Set the decompression registry for use in the channel. This is an advanced API call and shouldn't be used unless you are using custom message encoding. The default supported decompressors are in DecompressorRegistry.getDefaultInstance().

Specified by:

decompressorRegistry in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

compressorRegistry

public ManagedChannelImplBuilder compressorRegistry(CompressorRegistry registry)

Description copied from class: ManagedChannelBuilder

Set the compression registry for use in the channel. This is an advanced API call and shouldn't be used unless you are using custom message encoding. The default supported compressors are in CompressorRegistry.getDefaultInstance().

Specified by:

compressorRegistry in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

userAgent

public ManagedChannelImplBuilder userAgent(@Nullable
 String userAgent)

Description copied from class: ManagedChannelBuilder

Provides a custom User-Agent for the application.

It's an optional parameter. The library will provide a user agent independent of this option. If provided, the given agent will prepend the library's user agent information.

Specified by:

userAgent in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

overrideAuthority

public ManagedChannelImplBuilder overrideAuthority(String authority)

Description copied from class: ManagedChannelBuilder

Overrides the authority used with TLS and HTTP virtual hosting. It does not change what host is actually connected to. Is commonly in the form host:port.

If the channel builder overrides authority, any authority override from name resolution result (via EquivalentAddressGroup.ATTR_AUTHORITY_OVERRIDE) will be discarded.

This method is intended for testing, but may safely be used outside of tests as an alternative to DNS overrides.

Specified by:

overrideAuthority in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

idleTimeout

public ManagedChannelImplBuilder idleTimeout(long value,
 TimeUnit unit)

Description copied from class: ManagedChannelBuilder

Set the duration without ongoing RPCs before going to idle mode.

In idle mode the channel shuts down all connections, the NameResolver and the LoadBalancer. A new RPC would take the channel out of idle mode. A channel starts in idle mode. Defaults to 30 minutes.

This is an advisory option. Do not rely on any specific behavior related to this option.

Specified by:

idleTimeout in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

maxRetryAttempts

public ManagedChannelImplBuilder maxRetryAttempts(int maxRetryAttempts)

Description copied from class: ManagedChannelBuilder

Sets the maximum number of retry attempts that may be configured by the service config. If the service config specifies a larger value it will be reduced to this value. Setting this number to zero is not effectively the same as disableRetry() because the former does not disable transparent retry.

This method may not work as expected for the current release because retry is not fully implemented yet.

Overrides:

maxRetryAttempts in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

maxHedgedAttempts

public ManagedChannelImplBuilder maxHedgedAttempts(int maxHedgedAttempts)

Description copied from class: ManagedChannelBuilder

Sets the maximum number of hedged attempts that may be configured by the service config. If the service config specifies a larger value it will be reduced to this value.

This method may not work as expected for the current release because retry is not fully implemented yet.

Overrides:

maxHedgedAttempts in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

retryBufferSize

public ManagedChannelImplBuilder retryBufferSize(long bytes)

Description copied from class: ManagedChannelBuilder

Sets the retry buffer size in bytes. If the buffer limit is exceeded, no RPC could retry at the moment, and in hedging case all hedges but one of the same RPC will cancel. The implementation may only estimate the buffer size being used rather than count the exact physical memory allocated. The method does not have any effect if retry is disabled by the client.

This method may not work as expected for the current release because retry is not fully implemented yet.

Overrides:

retryBufferSize in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

perRpcBufferLimit

public ManagedChannelImplBuilder perRpcBufferLimit(long bytes)

Description copied from class: ManagedChannelBuilder

Sets the per RPC buffer limit in bytes used for retry. The RPC is not retriable if its buffer limit is exceeded. The implementation may only estimate the buffer size being used rather than count the exact physical memory allocated. It does not have any effect if retry is disabled by the client.

This method may not work as expected for the current release because retry is not fully implemented yet.

Overrides:

perRpcBufferLimit in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

disableRetry

public ManagedChannelImplBuilder disableRetry()

Description copied from class: ManagedChannelBuilder

Disables the retry and hedging subsystem provided by the gRPC library. This is designed for the case when users have their own retry implementation and want to avoid their own retry taking place simultaneously with the gRPC library layer retry.

Overrides:

disableRetry in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

enableRetry

public ManagedChannelImplBuilder enableRetry()

Description copied from class: ManagedChannelBuilder

Enables the retry and hedging subsystem which will use per-method configuration. If a method is unconfigured, it will be limited to transparent retries, which are safe for non-idempotent RPCs. Service config is ideally provided by the name resolver, but may also be specified via ManagedChannelBuilder.defaultServiceConfig(java.util.Map<java.lang.String, ?>).

Overrides:

enableRetry in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

setBinaryLog

public ManagedChannelImplBuilder setBinaryLog(BinaryLog binlog)

Description copied from class: ManagedChannelBuilder

Sets the BinaryLog object that this channel should log to. The channel does not take ownership of the object, and users are responsible for calling Closeable.close().

Overrides:

setBinaryLog in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Parameters:

binlog - the object to provide logging.

Returns:

this

maxTraceEvents

public ManagedChannelImplBuilder maxTraceEvents(int maxTraceEvents)

Description copied from class: ManagedChannelBuilder

Sets the maximum number of channel trace events to keep in the tracer for each channel or subchannel. If set to 0, channel tracing is effectively disabled.

Overrides:

maxTraceEvents in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

proxyDetector

public ManagedChannelImplBuilder proxyDetector(@Nullable
 ProxyDetector proxyDetector)

Description copied from class: ManagedChannelBuilder

Sets the proxy detector to be used in addresses name resolution. If null is passed the default proxy detector will be used. For how proxies work in gRPC, please refer to the documentation on ProxyDetector.

Overrides:

proxyDetector in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

defaultServiceConfig

public ManagedChannelImplBuilder defaultServiceConfig(@Nullable
 Map<String,?> serviceConfig)

Description copied from class: ManagedChannelBuilder

Provides a service config to the channel. The channel will use the default service config when the name resolver provides no service config or if the channel disables lookup service config from name resolver (see ManagedChannelBuilder.disableServiceConfigLookUp()). The argument serviceConfig is a nested map representing a Json object in the most natural way:

Json entry	Java Type
object	Map
array	List
string	String
number	Double
boolean	Boolean
null	null

If null is passed, then there will be no default service config.

Your preferred JSON parser may not produce results in the format expected. For such cases, you can convert its output. For example, if your parser produces Integers and other Numbers in addition to Double:

@SuppressWarnings("unchecked")
 private static Object convertNumbers(Object o) {
   if (o instanceof Map) {
     ((Map) o).replaceAll((k,v) -> convertNumbers(v));
   } else if (o instanceof List) {
     ((List) o).replaceAll(YourClass::convertNumbers);
   } else if (o instanceof Number && !(o instanceof Double)) {
     o = ((Number) o).doubleValue();
   }
   return o;
 }

Overrides:

defaultServiceConfig in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

disableServiceConfigLookUp

public ManagedChannelImplBuilder disableServiceConfigLookUp()

Description copied from class: ManagedChannelBuilder

Disables service config look-up from the naming system, which is enabled by default.

Overrides:

disableServiceConfigLookUp in class ManagedChannelBuilder<ManagedChannelImplBuilder>

Returns:

this

public void setStatsEnabled(boolean value)

Disable or enable stats features. Enabled by default.

For the current release, calling setStatsEnabled(true) may have a side effect that disables retry.

setStatsRecordStartedRpcs

public void setStatsRecordStartedRpcs(boolean value)

Disable or enable stats recording for RPC upstarts. Effective only if setStatsEnabled(boolean) is set to true. Enabled by default.

setStatsRecordFinishedRpcs
