Types

type IntMapper

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

IntConversor is a type that allows to map numbers between two or more ranges

func New

func New() IntMapper

Returns a new initialized conversor

func (*IntMapper) AddMapping

func (ic *IntMapper) AddMapping(from, to, length int)

Adds a new mapping. The behaviour is not defined for multiple overlapping ranges.

func (IntMapper) IsMapped

func (ic IntMapper) IsMapped(n int) bool

IsMapped returns true if the given number is inside a mapped rule

func (IntMapper) Transform

func (ic IntMapper) Transform(n int) int

Transform applies the mappings to the given integer n. If no mappings are found then n is returned
