type DomainTree ¶
type DomainTree[T any] domainNode[T]
DomainTree is a domain tree.
func Create ¶
func Create[T any]() *DomainTree[T]
Create creates a tree like structure to add arbitrary data to DNS names. The DomainTree splits the domain name based on the dot (.), reverses the resulting list and add all strings the tree in order. It has support for wildcard domain names the tree nodes (`Set`), but not during retrieval (Get and Has). Get always returns the most specific node; it doesn't immediately return the node upon finding a wildcard node.
func (*DomainTree[T]) Get ¶
func (tree *DomainTree[T]) Get(fqdn string) T
Get retrieves the attached data from a given FQDN. The tree will return the data entry for the most specific FQDN entry. If no entry is found Get will return the default value for the specific type.
tree.Set("*.example.com", 1) tree.Set("a.example.com", 2) tree.Get("a.example.com") // 2 tree.Get("a.a.example.com") // 1 tree.Get("other.com") // 0
func (*DomainTree[T]) Has ¶
func (tree *DomainTree[T]) Has(fqdn string) bool
Has returns if the tree contains data for given FQDN.
func (*DomainTree[T]) Set ¶
func (tree *DomainTree[T]) Set(fqdn string, data T)
Set adds given data to the given fqdn. The FQDN can contain a wildcard on the start. example fqdn: *.example.com
