Method Details

getDefaultPort

public int getDefaultPort()

The port number used in case the target or the underlying naming system doesn't provide a port number.

Since:

1.21.0

getProxyDetector

public ProxyDetector getProxyDetector()

If the NameResolver wants to support proxy, it should inquire this ProxyDetector. See documentation on ProxyDetector about how proxies work in gRPC.

Since:

1.21.0

getSynchronizationContext

public SynchronizationContext getSynchronizationContext()

Returns the SynchronizationContext where NameResolver.start(Listener2), NameResolver.shutdown() and NameResolver.refresh() are run from.

Since:

1.21.0

getScheduledExecutorService

@ExperimentalApi("https://github.com/grpc/grpc-java/issues/6454")
public ScheduledExecutorService getScheduledExecutorService()

Returns a ScheduledExecutorService for scheduling delayed tasks.

This service is a shared resource and is only meant for quick tasks. DO NOT block or run time-consuming tasks.

The returned service doesn't support shutdown() and shutdownNow(). They will throw if called.

Since:

1.26.0

getServiceConfigParser

public NameResolver.ServiceConfigParser getServiceConfigParser()

Returns the NameResolver.ServiceConfigParser.

Since:

1.21.0

getChannelLogger

@ExperimentalApi("https://github.com/grpc/grpc-java/issues/6438")
public ChannelLogger getChannelLogger()

Returns the ChannelLogger for the Channel served by this NameResolver.

Since:

1.26.0

getOffloadExecutor

@Nullable
public Executor getOffloadExecutor()

Returns the Executor on which this resolver should execute long-running or I/O bound work. Null if no Executor was set.

Since:

1.25.0

getOverrideAuthority

@Nullable
@ExperimentalApi("https://github.com/grpc/grpc-java/issues/9406")
public String getOverrideAuthority()

Returns the overrideAuthority from channel ManagedChannelBuilder.overrideAuthority(java.lang.String). Overrides the host name for L7 HTTP virtual host matching. Almost all name resolvers should not use this.

Since:

1.49.0

toString

public String toString()

Overrides:

toString in class Object

toBuilder

public NameResolver.Args.Builder toBuilder()

Returns a builder with the same initial values as this object.

Since:

1.21.0

newBuilder

public static NameResolver.Args.Builder newBuilder()

Creates a new builder.

Since:

1.21.0
