Method Detail

handleResolvedAddresses

@Deprecated
public void handleResolvedAddresses(LoadBalancer.ResolvedAddresses resolvedAddresses)

Deprecated.

Description copied from class: LoadBalancer

Handles newly resolved server groups and metadata attributes from name resolution system. servers contained in EquivalentAddressGroup should be considered equivalent but may be flattened into a single list if needed.

Implementations should not modify the given servers.

Overrides:

handleResolvedAddresses in class LoadBalancer

Parameters:

resolvedAddresses - the resolved server addresses, attributes, and config.

acceptResolvedAddresses

public Status acceptResolvedAddresses(LoadBalancer.ResolvedAddresses resolvedAddresses)

Description copied from class: LoadBalancer

Accepts newly resolved addresses from the name resolution system. The EquivalentAddressGroup addresses should be considered equivalent but may be flattened into a single list if needed.

Implementations can choose to reject the given addresses by returning false.

Implementations should not modify the given addresses.

Overrides:

acceptResolvedAddresses in class LoadBalancer

Parameters:

resolvedAddresses - the resolved server addresses, attributes, and config.

Returns:

true if the resolved addresses were accepted. false if rejected.

handleNameResolutionError

public void handleNameResolutionError(Status error)

Description copied from class: LoadBalancer

Handles an error from the name resolution system.

Specified by:

Parameters:

error - a non-OK status

shutdown

public void shutdown()

Description copied from class: LoadBalancer

The channel asks the load-balancer to shutdown. No more methods on this class will be called after this method. The implementation should shutdown all Subchannels and OOB channels, and do any other cleanup as necessary.
