from(Stanza)
MethodEvery PacketExtension class must have a static from()
method that retrieves that extension for a given Stanza (if any).
Sample Code
public static RSMSet from(Stanza) {
return packet.getExtension(ELEMENT, NAMESPACE);
}
Sometimes certain PacketExtension's are only found in one stanza type, in that case, specify the parameter type. For example public static CarbonExtension getFrom(Message)
.
