Method Details

shouldAutoClose

public boolean shouldAutoClose()

Description copied from interface: TransportChannelProvider

Indicates whether the TransportChannel should be closed by the containing client class.

Specified by:

shouldAutoClose in interface TransportChannelProvider

needsExecutor

public boolean needsExecutor()

Description copied from interface: TransportChannelProvider

True if the TransportProvider needs an executor.

Specified by:

needsExecutor in interface TransportChannelProvider

withExecutor

public FixedTransportChannelProvider withExecutor(ScheduledExecutorService executor)

Specified by:

withExecutor in interface TransportChannelProvider

withExecutor

public FixedTransportChannelProvider withExecutor(Executor executor)

Description copied from interface: TransportChannelProvider

Sets the executor to use when constructing a new TransportChannel.

Specified by:

withExecutor in interface TransportChannelProvider

needsHeaders

public boolean needsHeaders()

Description copied from interface: TransportChannelProvider

True if the TransportProvider has no headers provided.

Specified by:

needsHeaders in interface TransportChannelProvider

withHeaders

public FixedTransportChannelProvider withHeaders(Map<String,String> headers)

Description copied from interface: TransportChannelProvider

Sets the headers to use when constructing a new TransportChannel.

This method should only be called if TransportChannelProvider.needsHeaders() returns true.

Specified by:

withHeaders in interface TransportChannelProvider

needsEndpoint

public boolean needsEndpoint()

Description copied from interface: TransportChannelProvider

True if the TransportProvider has no endpoint set.

Specified by:

needsEndpoint in interface TransportChannelProvider

withEndpoint

public TransportChannelProvider withEndpoint(String endpoint)

Description copied from interface: TransportChannelProvider

Sets the endpoint to use when constructing a new TransportChannel.

This method should only be called if TransportChannelProvider.needsEndpoint() returns true.

Specified by:

withEndpoint in interface TransportChannelProvider

acceptsPoolSize

@Deprecated
public boolean acceptsPoolSize()

Deprecated.

FixedTransportChannelProvider doesn't support ChannelPool configuration

Description copied from interface: TransportChannelProvider

Reports whether this provider allows pool size customization.

Specified by:

acceptsPoolSize in interface TransportChannelProvider

withPoolSize

@Deprecated
public TransportChannelProvider withPoolSize(int size)

Deprecated.

FixedTransportChannelProvider doesn't support ChannelPool configuration

Description copied from interface: TransportChannelProvider

Number of underlying transport channels to open. Calls will be load balanced across them.

Specified by:

withPoolSize in interface TransportChannelProvider

getTransportChannel

public TransportChannel getTransportChannel()
                                     throws IOException

Description copied from interface: TransportChannelProvider

Provides a Transport, which could either be a new instance for every call, or the same instance, depending on the implementation.

If TransportChannelProvider.needsExecutor() is true, then TransportChannelProvider.withExecutor(Executor) needs to be called first to provide an executor.

If TransportChannelProvider.needsHeaders() is true, then TransportChannelProvider.withHeaders(Map) needs to be called first to provide headers.

if TransportChannelProvider.needsEndpoint() is true, then TransportChannelProvider.withEndpoint(String) needs to be called first to provide an endpoint.

Specified by:

getTransportChannel in interface TransportChannelProvider

Throws:

IOException

getTransportName

public String getTransportName()

Description copied from interface: TransportChannelProvider

The name of the transport.

This string can be used for identifying transports for switching logic.

Specified by:

getTransportName in interface TransportChannelProvider

needsCredentials

public boolean needsCredentials()

Description copied from interface: TransportChannelProvider

True if credentials are needed before channel creation.

Specified by:

needsCredentials in interface TransportChannelProvider

withCredentials

public TransportChannelProvider withCredentials(com.google.auth.Credentials credentials)

Description copied from interface: TransportChannelProvider

Sets the credentials that will be applied before channel creation.

Specified by:

withCredentials in interface TransportChannelProvider

create

public static FixedTransportChannelProvider create(TransportChannel transportChannel)

Creates a FixedTransportChannelProvider.
