Alternate ways to Load State for Entities

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

Loading state from a file

// Load the state by passing in the path & filename.
mortgageEntity.LoadXml("Mortgage.xml");

Loading state from an XML string

// Load state from an XML string.
mortgageEntity.ParseXml("<Mortgage><LoanInfo><Principal>500000</Principal><APR>7</APR><TermInYears>30</TermInYears></LoanInfo><PaymentSummary /></Mortgage>");

Manually wiring up an Entity

//create ruleapp entities
Entity mortgageEntity = ruleSession.CreateEntity("Mortgage");
Entity loanInfo = ruleSession.CreateEntity("LoanInfo");
Entity paymentSummary = ruleSession.CreateEntity("PaymentSummary");

//set loanInfo values

loanInfo.Fields["Principal"].Value = 250000;
loanInfo.Fields["APR"].Value = 5.25;
loanInfo.Fields["TermInYears"].Value = 30;

//associate loanInfo entity to an Mortgage entity field
mortgageEntity.Fields["LoanInfo"].Value = loanInfo;

//associate paymentSummary entity to Mortgage entity field
mortgageEntity.Fields["PaymentSummary"].Value = paymentSummary;

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.
