Class ConfigurationSetManager

Responsible for creating, deleting and checking for the existence of configuration sets.

Inheritance

System.Object

ConfigurationSetManager

Namespace: MESL.SqlRace.Domain

Assembly: MESL.SqlRace.Domain.dll

Syntax

public class ConfigurationSetManager : Object, IConfigurationSetManager

Remarks

Then ConfigurationSetManager will return a ConfigurationSet instance when the Create method is called which can then be used to add new configuration items.

Examples

The following is an example of using the ConfigurationSetManager to create a ConfigurationSet to add a simple shared configuration set:

// Local database connection string
string connectionString = @"Data Source=.\sqlexpress;Initial Catalog=SQLRACE01;Integrated Security=SSPI";

// Initialise SQL Race
Core.Initialize();

// Create simple configuration Set
ConfigurationSetManager configSetManager = ConfigurationSetManager.CreateConfigurationSetManager();
ConfigurationSet configSet = configSetManager.Create(connectionString, "Configuration set name", "Configuration set description");
configSet.AddParameter(new Parameter("Identifier", "Name", "Description", 1000, 0, 1000, 0, 0, 0xFF, 0, "RationalConversion", 1));
configSet.AddChannel(new Channel(1, "Name", 100, DataType.Unsigned8Bit, ChannelDataSourceType.Periodic));
configSet.AddConversion(new RationalConversion("RationalConversion", "units", "format", 0, 1, 0, 0, 0, 1));
try
{
  configSet.Commit();
} 
catch (ConfigurationSetAlreadyExistsException ex)
{
 // ConfigurationSet can be committed only once. It cannot be updated - new ConfigurationSet should be created instead
 Log.Warn($"Commit of a ConfigurationSet {configurationSet.Identifier} failed. The config set already exists"); 
}

An instance of ConfigurationSet can be committed once only.
