Interface ConfigurationStorage

public interface ConfigurationStorage

Interface for object to save and load configuration data

Provide implementation instance of this interface to save and load serialized configuration. Configuration data is serialized according to the configuration schema.

Configuration storage can be added using ConfigurationPersistenceManager accessed through KaaClient interface.

 class FileConfigurationStorage implements ConfigurationStorage {
     public void saveConfiguration(ByteBuffer buffer) {
         ...
     }
     public ByteBuffer loadConfiguration() {
         ...
     }
 }
 ...
 // Assuming Kaa instance is created
 KaaClient kaaClient = kaa.getClient();

 ConfigurationStorage configurationStorage = new FileConfigurationStorage();
 kaaClient.getConfigurationPersistenceManager().setConfigurationStorage(configurationStorage);
