Class NetworkAdapter

java.lang.Object
  com.webrenderer.event.NetworkAdapter

All Implemented Interfaces:

java.util.EventListener, NetworkListener

public abstract class NetworkAdapter

extends java.lang.Object

implements NetworkListener

An abstract adapter class for receiving network events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Extend this class to create a NetworkEvent listener and override the methods for the events of interest. (If you implement the NetworkListener interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you only have to define methods for events you care about.)

Create a listener object using the extended class and then register it with a browser using the browser's addNetworkListener method. When a network event occurs, the relevant method in the listener object is invoked and the NetworkEvent is passed to it.

Availble Methods from NetworkEvent at the time this event is fired:

• e.getURL()
• e.getMutableRequestHeaders()

Specified by:

onHTTPInterceptHeaders in interface NetworkListener

onProgressChange

public void onProgressChange(NetworkEvent e)

Description copied from interface: NetworkListener

Invoked when the progress of a document download changes.
Availble Methods from NetworkEvent at the time this event is fired:

• e.getCurrentProgress()
• e.getMaximumProgress()

Specified by:

onProgressChange in interface NetworkListener

onDocumentLoad

public void onDocumentLoad(NetworkEvent e)

Description copied from interface: NetworkListener

Availble Methods from NetworkEvent at the time this event is fired: None

Specified by:

onDocumentLoad in interface NetworkListener

onDocumentComplete

public void onDocumentComplete(NetworkEvent e)

Description copied from interface: NetworkListener

Invoked when a document stops loading in a browser. This may be invoked multiple times if a page has frames.
Availble Methods from NetworkEvent at the time this event is fired: e.getURL()

Specified by:

onDocumentComplete in interface NetworkListener

onNetworkStatus

public void onNetworkStatus(NetworkEvent e)

Description copied from interface: NetworkListener

Invoked when the status of the network has changed.

onNetworkStatus in interface NetworkListener

onNetworkError

public void onNetworkError(NetworkEvent e)

Description copied from interface: NetworkListener

Invoked when an error occurs on the network.
Availble Methods from NetworkEvent at the time this event is fired:

• e.getFailure()

Specified by:

onNetworkError in interface NetworkListener

onHTTPResponse

public void onHTTPResponse(NetworkEvent e)

Description copied from interface: NetworkListener

Invoked from an IMozillaBrowserCanvas when Http Response data is sent back from a request.
Availble Methods from NetworkEvent at the time this event is fired:

• e.getURL()
• e.getStatusText()
• e.getStatus()
• e.getResponseHeaders()
• e.getRequestHeaders()
