func Get(addr resolver.Address) []string
Get returns the hierarchical path of addr.
func Group(addrs []resolver.Address) map[string][]resolver.Address
Group splits a slice of addresses into groups based on the first hierarchy path. The first hierarchy path will be removed from the result.
Input: [
{addr0, path: [p0, wt0]}
{addr1, path: [p0, wt1]}
{addr2, path: [p1, wt2]}
{addr3, path: [p1, wt3]}
]
Addresses will be split into p0/p1, and the p0/p1 will be removed from the path.
Output:
{
p0: [
{addr0, path: [wt0]},
{addr1, path: [wt1]},
],
p1: [
{addr2, path: [wt2]},
{addr3, path: [wt3]},
],
}
If hierarchical path is not set, or has no path in it, the address is dropped.
func Set(addr resolver.Address, path []string) resolver.Address
Set overrides the hierarchical path in addr with path.
