type Resolver

type Resolver struct {
	RootNameServers []connection.Info

}

Resolver provides methods to resolve names in RAINS.

func New

func New(rootNS, forwarders []connection.Info, mode ResolutionMode, addr connection.Info) *Resolver

New creates a resolver with the given parameters and default settings

func (*Resolver) ClientLookup

func (r *Resolver) ClientLookup(query *query.Name) (*message.Message, error)

ClientLookup forwards the query to the specified forwarders or performs a recursive lookup starting at the specified root servers. It returns the received information.

func (*Resolver) ServerLookup

func (r *Resolver) ServerLookup(query *query.Name, connInfo connection.Info, token token.Token)

ServerLookup forwards the query to the specified forwarders or performs a recursive lookup starting at the specified root servers. It sends the received information to conInfo.
