Method Details

parseServiceConfig

public NameResolver.ConfigOrError parseServiceConfig(Map<String,?> rawServiceConfig)

Description copied from class: NameResolver.ServiceConfigParser

Parses and validates the service configuration chosen by the name resolver. This will return a NameResolver.ConfigOrError which contains either the successfully parsed config, or the Status representing the failure to parse. Implementations are expected to not throw exceptions but return a Status representing the failure. The value inside the NameResolver.ConfigOrError should implement equals() and hashCode().

Specified by:

parseServiceConfig in class NameResolver.ServiceConfigParser

Parameters:

rawServiceConfig - The Map representation of the service config

Returns:

a tuple of the fully parsed and validated channel configuration, else the Status.
