Types

type IO 

type IO struct{}

Parser can be used to parse and encode RAINS zone files

func (IO) Decode 

func (p IO) Decode(zoneFile []byte) ([]section.WithSigForward, error)

Decode returns all assertions contained in the given zonefile

func (IO) DecodeNameQueriesUnsafe 

func (p IO) DecodeNameQueriesUnsafe(encoding []byte) []*query.Name

DecodeNameQueriesUnsafe takes as input a byte string of name queries encoded in a format resembling the zone file format. It returns the queries. It panics when the input format is incorrect.

func (IO) Encode 

func (p IO) Encode(sections []section.Section) string

Encode returns the given sections represented in the zone file format if it is a zoneSection. In all other cases it returns the sections in a displayable format similar to the zone file format

func (IO) EncodeAndStore 

func (p IO) EncodeAndStore(path string, sections []section.Section) error

EncodeAndStore stores the given section represented in zone file format if it is an assertion, shard, pshard, or zone. In all other cases it stores the section in a displayable format similar to the zone file format

func (IO) EncodeSection 

func (p IO) EncodeSection(s section.Section) string

EncodeSection returns the given section represented in the zone file format if it is a zoneSection. In all other cases it returns the section in a displayable format similar to the zone file format

func (IO) LoadZonefile 

func (p IO) LoadZonefile(path string) ([]section.WithSigForward, error)

LoadZonefile takes as input a path to a file containing a zone in zonefile format. It returns the zone exactly as it is in the zonefile or an error in case of failure.

type WordScanner 

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

WordScanner uses bufio.Scanner to scan words of the input. Additionally it keeps track of the line (of the input) on which the scanner currently is

func NewWordScanner 

func NewWordScanner(data []byte) *WordScanner

NewWordScanner returns a WordScanner

func (*WordScanner) LineNumber 

func (ws *WordScanner) LineNumber() int

LineNumber returns the number of the line of the input data on which the current Token of the scanner is.

func (*WordScanner) Scan 

func (ws *WordScanner) Scan() bool

Scan moves the Scanner to the next Token, which will then be available through the Bytes or Text method. False is returned when the scan stops, either by reaching the end of the input or an error.

func (*WordScanner) Text 

func (ws *WordScanner) Text() string

Text returns the value of the current Token generated by a call to Scan as a newly allocated string.

func (*WordScanner) TextLine 

func (ws *WordScanner) TextLine() string

type ZFPLex 

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

func (*ZFPLex) Error 

func (l *ZFPLex) Error(s string)

The parser calls this method on a parse error.

func (*ZFPLex) Lex 

func (l *ZFPLex) Lex(lval *ZFPSymType) int

type ZFPLexer 

type ZFPLexer interface {
	Lex(lval *ZFPSymType) int
	Error(s string)
}

type ZFPParser 

type ZFPParser interface {
	Parse(ZFPLexer) int
	Lookahead() int
}

func ZFPNewParser 

func ZFPNewParser() ZFPParser

type ZFPParserImpl 

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

func (*ZFPParserImpl) Lookahead 

func (p *ZFPParserImpl) Lookahead() int

func (*ZFPParserImpl) Parse 

func (ZFPrcvr *ZFPParserImpl) Parse(ZFPlex ZFPLexer) int

type ZFPSymType 

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

type ZoneFileIO 

type ZoneFileIO interface {
	//Decode takes as input a byte string of section(s) in zonefile format. It returns a slice of
	//all contained assertions, shards, and zones in the provided order or an error in case of
	//failure.
	Decode(zoneFile []byte) ([]section.WithSigForward, error)

	//DecodeNameQueriesUnsafe takes as input a byte string of name queries encoded in a format
	//resembling the zone file format. It returns the queries. It panics when the input format is
	//incorrect.
	DecodeNameQueriesUnsafe(encoding []byte) []*query.Name

	//LoadZonefile takes as input a path to a file containing a zone in zonefile
	//format. It returns the zone exactly as it is in the zonefile or an error
	//in case of failure.
	LoadZonefile(path string) ([]section.WithSigForward, error)

	//Encode returns the given sections represented in zone file format if it is an assertion,
	//shard, or zone. In all other cases it returns the sections in a displayable format similar to
	//the zonefile format
	Encode(sections []section.Section) string

	//EncodeSection returns the given section represented in zone file format if it is an assertion,
	//shard, or zone. In all other cases it returns the section in a displayable format similar to
	//the zonefile format
	EncodeSection(section section.Section) string

	//EncodeAndStore stores the given sections represented in zone file format if it is an
	//assertion, shard, pshard, or zone. In all other cases it stores the sections in a displayable
	//format similar to the zone file format
	EncodeAndStore(path string, section []section.Section) error
}

ZoneFileIO is the interface for all parsers of zone files for RAINS
