Types

type ParseState

type ParseState struct {
	Parenthesis  bool
	PreviousName string
}

ParseState represents the current state of the zone parser. ParseState is used by parseZone and does not need to be used manually.

type Record

type Record struct {
	Class   string
	Content string
	Host    string
	Ttl     uint
	Type    string
}

type Zone

type Zone struct {
	Origin        string
	Records       []Record
	SOAEmail      string
	SOANameserver string
	Ttl           uint
	Serial        uint
}

type ZoneSOA

type ZoneSOA struct {
	Email      string
	Nameserver string
	Serial     string
	Refresh    string
	Retry      string
	Expire     string
	Minimum    string
}

type ZoneScanner

type ZoneScanner struct {
	// contains filtered or unexported fields
}

ZoneScanner is a simple scanner that provides functionality for zone files. It should not be instantiated manually, instead use NewZoneScanner

func NewZoneScanner

func NewZoneScanner(zone string) *ZoneScanner

NewZoneScanner returnes a new ZoneScanner with the zones content.

func (*ZoneScanner) HasNext

func (z *ZoneScanner) HasNext() bool

func (*ZoneScanner) Next

func (z *ZoneScanner) Next(n int) string

Next Returns the next n chars of the scanners content and sets the new position. If n is greater than the remaining content, only the remaining content will be returned.

func (*ZoneScanner) Peek

func (z *ZoneScanner) Peek(n int) string

Peek Returns the next n chars of the scanners content without changing the position. If n is greater than the remaining content, only the remaining content will be returned.

func (*ZoneScanner) SkipToEoL

func (z *ZoneScanner) SkipToEoL()

SkipToEoL goes to the end of the line

func (*ZoneScanner) SkipWhitespace

func (z *ZoneScanner) SkipWhitespace()

SkipWhitespace goes to the next char that is not whitespace
