Types

type Map

type Map map[string]interface{}

Map is a map that maps domain names to some other data

type Tree

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

Tree is a radix-tree that supports domain-based matching including wildcard prefixes (specified with a leading .)

func NewTree

func NewTree() *Tree

NewTree constructs a new empty Tree

func NewTreeFromMap

func NewTreeFromMap(initial Map) *Tree

NewTreeFromMap constructs a Tree initialized from a given Map

func (*Tree) BestMatch

func (tree *Tree) BestMatch(domain string) (result interface{}, found bool)

BestMatch finds the best match for the given domain

func (*Tree) Get

func (tree *Tree) Get(domain string) (result interface{}, found bool)

Get gets the entry exactly matching the given domain

func (*Tree) Insert

func (tree *Tree) Insert(domain string, value interface{})

Insert inserts a new value into the tree

func (*Tree) ToMap

func (tree *Tree) ToMap() Map

ToMap obtains the Tree as a Map

func (*Tree) Walk

func (tree *Tree) Walk(fn func(domain string, value interface{}) bool)

Walk walks the tree, calling the supplied fn for each domain/value pair in the tree and continuing the walk as long as fn returns true.
