Functions

func Abs

func Abs(a int64) int64

two's complement 64 bit abs value

func AvgMaxPos

func AvgMaxPos(vals []float64) (avg float64, max float64, maxPos float64)

UNUSED AvgMaxPos calculating mean (average), maximum value, and position of max value in a data set

func Exists

func Exists(path string) (bool, error)

UNUSED

• Name: Exists
• Purpose: Returns true if file or directory exists, false otherwise
• comments:

func IsIP

func IsIP(ip string) bool

UNUSED

• Name: IsIP
• Purpose: Returns true if string is a valid IP address, false otherwise
• comments:

func IsLoopback

func IsLoopback(ip string) bool

UNUSED

• Name: IsLoopback
• Purpose: Returns true if string is a valid IP address, false otherwise
• comments:

func IsSpecialIP

func IsSpecialIP(ip string) bool

UNUSED IsSpecialIP attempts to filter some IPs that we don't care about

func IsURL

func IsURL(str string) bool

UNUSED

• Name: IsURL
• Purpose: Returns true if string is a URL, false otherwise
• comments:

func Max

func Max(a int, b int) int

func Mean

func Mean(numList []float64) float64

UNUSED Mean calculating the mean (average) of a data set

func Min

func Min(a int, b int) int

retun the smaller of two integers

func RFC1918

func RFC1918(ip string) bool

RFC1918 returns true if it the ip looks non routable

func RemoveSortedDuplicates

func RemoveSortedDuplicates(sortedIn []int64) []int64

given a sorted slice, remove the duplicates

func Round

func Round(f float64) int64

rounding function since go doesn't have it

func StdDev

func StdDev(numList []float64) float64

UNUSED StdDev calculating the standard deviation (quantified amount of variation or dispersion) of a data set

func TypeConvert

func TypeConvert(m interface{}, desiredType reflect.Kind) (interface{}, int)

UNUSED

• Name: TypeConvert
• Purpose: Dynamic type converter
• comments:

func ValidIP

func ValidIP(ip string) bool

UNUSED ValidIP validates an ip

func Variance

func Variance(numList []float64) float64

UNUSED Variance calculating the variance of a data set

Types

type ByStringLength

type ByStringLength []string

ByStringLength Functions that, in combination with golang sort, allow users to sort a slice/list of strings by string length (shortest -> longest)

func (ByStringLength) Len

func (s ByStringLength) Len() int

func (ByStringLength) Less

func (s ByStringLength) Less(i, j int) bool

func (ByStringLength) Swap

func (s ByStringLength) Swap(i, j int)

type Cache

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

Cache is a simple cache mechanism to avoid db lookups

func NewCache

func NewCache() Cache

NewCache creates a new connection cache

func (Cache) Keys

func (c Cache) Keys() []string

UNUSED

func (Cache) Lookup

func (c Cache) Lookup(hash string) bool

Lookup a value in the cache, return true if present or false if not found. Once a lookup has been performed the value is cached so that the next lookup will cause the cache to return true.

type SortableInt64

type SortableInt64 []int64

SortableInt64 functions that allow a golang sort of int64s

func (SortableInt64) Len

func (s SortableInt64) Len() int

func (SortableInt64) Less

func (s SortableInt64) Less(i, j int) bool

func (SortableInt64) Swap

func (s SortableInt64) Swap(i, j int)
