NetGroup class constructor

netGroup = new NetGroup(connection, groupspec)

Constructs a NetGroup on the specified NetConnection object and joins it to the group specified by the groupspec

parameter. Use the GroupSpecifier class to build the

groupspec string. In Server-Side ActionScript, you can pass a

groupspec String or a GroupSpecifier object as the groupspec argument. The NetConnection must use the RTMFP

protocol.

Throws an Error if either argument is missing or null, if the NetGroup fails to join the group specified in the

groupspec parameter, or if the protocol is not RTMFP.

The status messages are dispatched to “NetGroup.onStatus()” on page 110.

Availability

Flash Media Server 4

Parameters

connection A NetConnection object. The protocol must be RTMFP.

groupspec To publish or play a stream in a peer-to-peer multicast group, specify a groupspec string or a

GroupSpecifier object. To create a groupspec string, call

GroupSpecifier.toString().

Example

The following example passes a GroupSpecifier object as the groupspec parameter:

netGroup = new NetGroup(myConnection, myGroupSpecifier);

The following example passes a GroupSpecifier string as the groupspec parameter:

netGroup = new NetGroup(myConnection, myGroupSpecifier.toString());

NetGroup.addMemberHint()

netGroup.addMemberHint(peerID)

Manually adds a record specifying that peerID is a member of the Group. An immediate connection to it is attempted

only if it is needed for the topology.

Availability

Flash Media Server 4

Parameters

peerID A String. The peerID to add to the set of potential neighbors.
