Creating Entities

  • Updated

Prerequisites: A valid RuleSession
Namespaces: InRule.Runtime
Classes: Entity, RuleSession
See Also: Retrieving a Rule Application, Creating a RuleSession

For typical entity models, there is a top level entity that provides access to all fields, sub-entities, and collections defined in the rule application.  The alternative independent entity model approach requires the use of Independent Rulesets.

Create blank Entity

//create a blank mortgage entity
Entity mortgageEntity = ruleSession.CreateEntity("Mortgage");

Create Entities with XML

// Create a mortgage entity with XML
Entity mortgageEntity = ruleSession.CreateEntity("Mortgage",@"<Mortgage>

Create the Entity model from a business object model

// Create a mortgage business object
Mortgage mortgage = new Mortgage();
LoanInfo loanInfo = new LoanInfo();
loanInfo.APR = 6.875m;
loanInfo.PropertyId = 1;
loanInfo.Principal = 500000;
loanInfo.TermInYears = 30;

mortgage.LoanInfo = loanInfo;
mortgage.PaymentSummary = new PaymentSummary();

Entity mortgageEntity = ruleSession.CreateEntity("Mortgage", mortgage);

Note: See also: Setting Fields examples

Note: In order to use object-based state, the rule application must first be bound to a .NET assembly schema.  See Binding to a .NET Assembly Schema in the main InRule Help file.
