Method Details
- getOptions
  
  Map<String,String> getOptions()
  
  Returns:
  
  Options that were set in the client config using the prefix scan.server.selector.opts.. The prefix will be stripped. For example if scan.server.selector.opts.k1=v1 is set in client config, then the returned map will contain k1=v1.
- getServiceEnv
  
  ServiceEnvironment getServiceEnv()
- getScanServers
  
  Supplier<Collection<ScanServerInfo>> getScanServers()
  
  Returns:
  
  the set of live ScanServers. Each time the supplier is called it may return something different. A good practice would be to call this no more than once per a call to ScanServerSelector.selectServers(SelectorParameters) so that decisions are made using a consistent set of scan servers.
