Defined at line 4039 of file fidling/gen/sdk/fidl/fuchsia.weave/fuchsia.weave/hlcpp/fuchsia/weave/cpp/fidl.h

ID. The endpoint ID is specified in, and this protocol retrieved from

[`fuchsia.weave/Stack.GetServiceDirectoryWatcher`].

Public Methods

void ~SvcDirectoryWatcher ()

void WatchServiceDirectory (WatchServiceDirectoryCallback callback)

Returns a vector of HostPorts for the watched endpoint ID.

First call returns the current list of HostPorts or blocks until the list

is available from the service. Subsequent calls will block until a new

ServiceDirectory lookup is made and will return the list associated with

the watched endpoint ID, which may or may not be the same as prior values.

Calling WatchServiceDirectory when a previous call is still pending will

cause the channel to be closed with `ZX_ERR_BAD_STATE`.
