FirstOrDefault<T>(Func<T, Boolean>, String, IPersistEntity)

Returns firs or default entitiy satysfying the condition utilizing secondary index for inverse relations. Always use this overload if you query for the entities on the other side of inverse relation (like all IfcRelations). It might be significantly optimized in the implementation of this interface especially if the data is stored in the database.

Declaration
T FirstOrDefault<T>(Func<T, bool> condition, string inverseProperty, IPersistEntity inverseArgument)
    where T : IPersistEntity
Parameters
Type Name Description
System.Func<T, System.Boolean> condition

Condition
System.String inverseProperty

Name of the property which is being evaluated
IPersistEntity inverseArgument

Entity which should be equal/contained in the property
Returns
Type Description
T
Type Parameters
