Hi, Folks:
Choice case seems interchangeable with Container+when, here is the example of Choice case
container system {
description
"Contains various system parameters.";
choice services {
description
"Configure externally available services.";
case ssh {
description
"SSH service-specific configuration.";
// more leafs, containers, and stuff here...
}
case tls {
description
"TLS service-specific configuration.";
// more leafs, containers, and stuff here...
}
}
}
I think it can be replaced with container+when representation as follows:
container system {
description
"Contains various system parameters.";
container services {
description
"Configure externally available services.";
leaf transport {
enum ssh {
description
"ssh";
}
enum tls {
description
"tls";
}
}
container "ssh" {
when "../transport=ssh" {
description
"active only when the transport is ssh";
}
description
"SSH service-specific configuration.";
// more leafs, containers, and stuff here...
}
container "tls" {
when "../transport=tls" {
description
"active only when the transport is tls";
}
description
"TLS service-specific configuration.";
// more leafs, containers, and stuff here...
}
}
}
However I didn't see any guidance on when to use Choice case or when to use Container+when?
Any thought about this?
