Functions

func GetIndexFromName 

func GetIndexFromName(name string) (int, error)

GetIndexFromName - Get the index of an interface from its name

Types

type Bridge 

type Bridge struct {
	Interface
	// contains filtered or unexported fields
}

func NewBridge 

func NewBridge(name string) (*Bridge, error)

func (*Bridge) Delete
