Removing Templates in the Language Editor
| Prerequisites | A valid RuleSession, A valid Entity |
| Namespaces | InRule.Repository, InRule.Repository.Vocabulary, InRule.Repository.Templates |
| Classes | RuleApplicationDef, TemplateDef |
| See Also | Embedding the Language Rule Editor |
| References | InRule.Repository.dll |
The following example demonstrates how to remove Templates from the Business Language Editor. This code must run before the Populate method for the Business Language Editor is called.
Removing built-in InRule Templates
// Create a new VocabularyDef if Vocabulary is null
if (ruleAppDef.Vocabulary == null)
{
ruleAppDef.Vocabulary = new VocabularyDef();
}
// Remove the "Minus" template by adding a TemplateAvailabilitySettings and setting availability to Exclude
ruleAppDef.Vocabulary.TemplateAvailabilitySettings.Add(TemplateLiterals.TemplateGuids.Minus,
InRule.Repository.Vocabulary.TemplateAvailability.Exclude);Removing Rule Templates
// Make sure the Vocabulary is not null
if (ruleAppDef.Vocabulary == null)
{
// Create a new VocabularyDef if null
ruleAppDef.Vocabulary = new VocabularyDef();
}
// Get rule template by name (Note: this is not the same as the Display Name)
TemplateDef templateDef = (TemplateDef)ruleAppDef.Vocabulary.Templates["ExpressionTemplateDef1"];
// Remove the template using it's GUID
ruleAppDef.Vocabulary.TemplateAvailabilitySettings.Add(templateDef.Guid,
TemplateAvailability.Exclude);Determine FieldDef Dependencies
| Prerequisites | A valid RuleRepositoryDefBase, A valid EvalNetwork |
| Namespaces | InRule.Repository, InRule.Repository.Infos |
| Classes | RuleApplicationDef, RuleRepositoryDefBase, DefUsageNetwork, FieldDef |
| References | InRule.Common.dll, InRule.Repository.dll |
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);
}
