Functions

func GetExternalIndex

func GetExternalIndex(index int) int

Get an External Index from a given integer

func IntToByteArray

func IntToByteArray(num int64, length int) []byte

Transforms a int64 to a byte array given a delim

func IntToCompactIndex

func IntToCompactIndex(integer int) []byte

Read an int and returns a Compact Index as byte array

func ReadCompactIndex

func ReadCompactIndex(reader *bytes.Reader) (int, int)

Reads byte from a buffer and returns an uncompacted index as int Due the variable length of a CompactIndex, this function moves forward the pointer of the passed reader

func ReadName

func ReadName(reader *bytes.Reader) (uint8, string)

Reads byte from a buffer and returns a name string Due the variable length of a Name, this function moves forward the pointer of the passed reader

func ReadNextBytes

func ReadNextBytes(file *os.File, params ...int) []byte

Read the next bytes with additional delim and offset options Params: file *os.File, delim int, offset int

func SetExportCount

func SetExportCount(file *os.File, expCnt []byte) error

func SetExportOffset

func SetExportOffset(file *os.File, expOfs []byte) error

func SetGenerations
