Types

type ConfMap

type ConfMap map[string]ConfMapSection

func MakeConfMap

func MakeConfMap() (confMap ConfMap)

MakeConfMap returns an newly created empty ConfMap

func MakeConfMapFromFile

func MakeConfMapFromFile(confFilePath string) (confMap ConfMap, err error)

MakeConfMapFromFile returns a newly created ConfMap loaded with the contents of the confFilePath-specified file

func MakeConfMapFromStrings

func MakeConfMapFromStrings(confStrings []string) (confMap ConfMap, err error)

func (ConfMap) Dump

func (confMap ConfMap) Dump() (confMapString string)

Dump returns a single string that, if passed written to a file used as input to MakeConfMapFromFile() would result in an identical ConfMap.

To enable efficient comparisons, the elements of the ConfMap will be sorted in the output (both by sectionName and by optionName).

func (confMap ConfMap) FetchOptionValueUUID(sectionName string, optionName string) (optionValue []byte, err error)

FetchOptionValueUUID returns [sectionName]optionName's single string value converted to a UUID ([16]byte)

From RFC 4122, a UUID string is defined as follows:

UUID                   = time-low "-" time-mid "-" time-high-and-version "-" clock-seq-and-reserved clock-seq-low "-" node
time-low               = 4hexOctet
time-mid               = 2hexOctet
time-high-and-version  = 2hexOctet
clock-seq-and-reserved = hexOctet
clock-seq-low          = hexOctet
node                   = 6hexOctet
hexOctet               = hexDigit hexDigit
hexDigit               = "0" / "1" / "2" / "3" / "4" / "5" / "6" / "7" / "8" / "9" / "a" / "b" / "c" / "d" / "e" / "f" / "A" / "B" / "C" / "D" / "E" / "F"

From RFC 4122, a UUID (i.e. "in memory") is defined as follows (BigEndian/NetworkByteOrder):

0                   1                   2                   3
 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
