?Hi,
I'm working on C# bindings. The goal is to obtain a more C# API for the API
users.
So I have create object for libvirt familly function (an object Connect,
Domain, Storage and so on).
All is almost done, but I need and advice about the way to handle object
properties. For example, for the Connect object, I expose a "RunningDomains"
property that can be used in this manner :
Connect myConn = new Connect("qemu+tcp://192.168.220.198/system");
List<Domain> runningDomains = myConn.RunningsDomains;
In the Connect object, the property "RunningDomains" is coded in this :
/// <summary>
/// Get the list of running domains
/// </summary>
public List<Domain> RunningDomains
{
get
{
if (_conn == IntPtr.Zero) return null;
int nbRunningDomain = NumOfDomains(_conn);
int[] runningDomainIds = new int[nbRunningDomain];
ListDomains(_conn, runningDomainIds, nbRunningDomain);
return runningDomainIds.Select(id => new
Domain(Domain.LookupByID(_conn, id), this)).ToList();
}
}
So the property call "virConnectNumOfDomains" and "virConnectListDomains" each
time the property is called. And I don't know if it is a good thing. The other
way, is to keep the list in the Connect object and handle domain adding or
removing in this via callbacks. This avoid multiple call to the librar.
Any advice ?
Regards,
Arnaud
