Hi Team
We wanted to serialize an InstanceIdentifier to String and then deserialize the string back to InstanceIdentifier when required.
Model definition used:
container services{
list service {
key name;
leaf name {
type string;
}
list service-port{
key id;
leaf id {
type uint32;
}
}
}
}
Here are the steps followed
serialization:
1. Using BindingNormalizedNodeSerializer, Convert the InstanceIdentifier to yangInstanceIdentifier
2. AbstractModuleStringInstanceIdentifierCodec is used to serialize the YangInstanceIdentifier to String
I/p: InstanceIdentifier<ServicePort> sport = InstanceIdentifier.create(Services.class).child(Service.class, new ServiceKey("MyService")).child(ServicePort.class, new ServicePortKey(20L));
O/p: /normalizednodedemo:services/normalizednodedemo:service[normalizednodedemo:name='MyService']/normalizednodedemo:service-port[normalizednodedemo:id='20']
Deserialization:
1. AbstractModuleStringInstanceIdentifierCodec is used to deserialize, the String to YangInstanceIdentifier
2. Using BindingNormalizedNodeSerializer, Convert yangInstanceIdentifier to InstanceIdentifier
I/p: /normalizednodedemo:services/normalizednodedemo:service[normalizednodedemo:name='MyService']/normalizednodedemo:service-port[normalizednodedemo:id='20']
o/p: Exception raised

NOTE: We are using Boron-SR3
Is this issue fixed in later releases? If not, Can you please suggest us how to fix the issue.
Thanks
