Determine FieldDef Dependencies

Prerequisites: A valid RuleRepositoryDefBase, A valid EvalNetwork
Namespaces: InRule.Repository, InRule.Repository.Infos
Classes:   RuleApplicationDef, RuleRepositoryDefBase, DefUsageNetwork, FieldDef

Determine FieldDef Dependencies

The following recursive method shows how to identify all FieldDef dependencies for a given RuleRepositoryDefBase object.

public static IEnumerable<DefUsage> GetDependentFieldDefs(RuleRepositoryDefBase def,
DefUsageNetwork network)
{
 // Create collection of all usages by the given definition
 var usages = network.GetDefUsages(def.Guid, true);

 // Return list of dependencies
 return usages;
}

Instantiate the DefUsageNetwork

The following code snippet demonstrates the proper way to create an instance of the DefUsageNetwork.

public static DefUsageNetwork GetDefUsageNetwork(RuleApplicationDef ruleAppDef)
{
 return DefUsageNetwork.Create(ruleAppDef);
}
