流利的NHibernate鉴别值 [英] Fluent NHibernate-discriminator value

问题描述

我需要为父类设置多个判别值。有可能吗？怎么做？

例如：



PARENT_CLASS



DiscriminateSubClassesOnColumn（COLUMN_NAME，X）;



CHILD_CLASS_1



DiscriminatorValue（Y ）;



CHILD_CLASS_2



DiscriminatorValue（Z）;



这是可能的。但是，如果我在COLUMN_NAME列中有超过这3个值，该怎么办？



例如，如果P和Q也是该列的可能值，那么该怎么办？我应该写吗？



DiscriminateSubClassesOnColumn（COLUMN_NAME，X，P，Q）;显然这是不可能写的。但我不知道该怎么做。有人可以帮帮我吗？



谢谢。

 ENTITY： 
 
  public   partial   class  InsuranceApprovalInvoice：OrderInsuranceApproval 
 {
 [DataMember（）] 
  public   virtual  PatientInvoice PatientInvoice { get ;  set ; } 
 
} 
  public   partial   class  InsuranceApprovalOrder：OrderInsuranceApproval 
 {
 [DataMember（）] 
  public   virtual 订单订单{ get ;  set ; } 
 
} 
  public   partial   class  InsuranceApprovalPackage：OrderInsuranceApproval 
 {
 [DataMember（）] 
  public   virtual  TreatmentPlanPackages TreatmentPlanPackages { get ;  set ; } 
 
} 
 
 MAPPER：
 
 DiscriminateSubClassesOnColumn（  ObjectTypeID）。AlwaysSelectWithValue（）
 .SubClass< insuranceapprovalinvoice>（（ int ）InsuranceApprovalTypeEnum.Invoice，
m = >  m.References（p = >  p.PatientInvoice，  InvoiceMasterID）。列（  ObjectID）。ReadOnly（））
 
 .SubClass< insuranceapprovalorder>（（ int ）InsuranceApprovalTypeEnum.Order ，
m = >  m.References（p = >  p.Order，  OrderID ）。列（  ObjectID）。ReadOnly（））
 
 .SubClass< insuranceapprovalpackage>（（ int ）InsuranceApprovalTypeEnum.Package，
m = >  m.References（p = >  p.TreatmentPlanPackages，  TreatmentPlanPackagesID）。列（  ObjectID）。ReadOnly（）） ; 
 < /   insuranceapprovalpackage  >  < /   insuranceapprovalorder  >  < /   insuranceapprovalinvoice  >  

I need to set more than one discriminate values for parent class. Is it possible to do and how?
For example:

PARENT_CLASS

DiscriminateSubClassesOnColumn("COLUMN_NAME", "X");

CHILD_CLASS_1

DiscriminatorValue("Y");

CHILD_CLASS_2

DiscriminatorValue("Z");

This is possible. But what if i have more than these 3 values in column "COLUMN_NAME"?

For example if "P" and "Q" are also possible values for that column what should i write?

DiscriminateSubClassesOnColumn("COLUMN_NAME", "X","P","Q"); Obviously this is not possible to write. But i don't know how to do this. Can someone help me?

Thanks.
