C# 클래스 Pathoschild.WebApi.NhibernateOdata.Internal.FixStringMethodsVisitor

Intercepts queries before they're parsed by NHibernate to rewrite unsupported lambdas for string.Contains, string.StartsWith(string) and string.EndsWith(string).
The expression tree generated by the ODataQueryOptions.ApplyTo method looks like the following sample. .Lambda #Lambda1<System.Func`2[Pathoschild.WebApi.NhibernateOdata.Tests.Models.Parent,System.Boolean]>(Pathoschild.WebApi.NhibernateOdata.Tests.Models.Parent $$it) { (.If ( $$it.Name == null | .Constant<System.Web.Http.OData.Query.Expressions.LinqParameterContainer+TypedLinqParameterContainer`1[System.String]>(System.Web.Http.OData.Query.Expressions.LinqParameterContainer+TypedLinqParameterContainer`1[System.String]).TypedProperty == null ) { null } .Else { (System.Nullable`1[System.Boolean]).Call ($$it.Name).Contains(.Constant<System.Web.Http.OData.Query.Expressions.LinqParameterContainer+TypedLinqParameterContainer`1[System.String]>(System.Web.Http.OData.Query.Expressions.LinqParameterContainer+TypedLinqParameterContainer`1[System.String]).TypedProperty) } == (System.Nullable`1[System.Boolean]).Constant<System.Web.Http.OData.Query.Expressions.LinqParameterContainer+TypedLinqParameterContainer`1[System.Boolean]>(System.Web.Http.OData.Query.Expressions.LinqParameterContainer+TypedLinqParameterContainer`1[System.Boolean]).TypedProperty) == .Constant<System.Nullable`1[System.Boolean]>(True) } The actual System.Web.Http.OData parser DOES NOT support the "replace" string method, so we can't make it go through NHibernate.
