# Class BonjourPublisher

java.lang.Object
com.codename1.io.bonjour.BonjourPublisher

public final class BonjourPublisher extends Object

Advertises a Bonjour / mDNS service on the local network.

A publisher registers a service of a given type and port; once registered any client on the same network running `BonjourBrowser.browse(type, ...)` will see it. `txt` records carry small key/value metadata (typical limit 255 bytes per value).

##### Example -- advertise an HTTP service on port 8080

    BonjourPublisher pub = BonjourPublisher.publish(
            "MyServer", "_http._tcp.", 8080, null);

    // when shutting down
    pub.unpublish();

On iOS the build pipeline appends `type` to `NSBonjourServices` in Info.plist automatically when this class is referenced; without that entry iOS 14+ silently rejects the publish.

- ## Method Details

  - ### publish

    public static BonjourPublisher publish(String name, String type, int port, Map<String,String> txt)
    Publishes a new service. `name` is shown to humans browsing services and must be unique on the local subnet; the OS may append a suffix to resolve collisions. `type` is the mDNS type (e.g. `_http._tcp.`). `port` is the listening port on this device. `txt` may be `null` or a String->String map of metadata.

  - ### getName

    public String getName()

  - ### getType

    public String getType()

  - ### getPort

    public int getPort()

  - ### unpublish

    public void unpublish()
    Removes the advertisement. Idempotent.
