c# - nHibernate Mapping BaseClass to Multiple tables -

i have group of objects share similar properties, inherit these base class. here simple example of doing.

i have 2 objects, employee , customer have corresponding tables. each contain list of addresses. address class shared between 2 objects, reside in 2 seperate tables employeeaddress , customeraddress.

employeeaddress - employeeid uniqueidentifier                   address varchar (50)                   zipcode varchar (10)                   city varchar (20)                   state id not null  customeraddress - customerid uniqueidentifier                   address varchar (50)                   zipcode varchar (10)                   city varchar (20)                   state id not null           

how can map address object 2 seperate tables? want able pull data either employeeaddress or customeraddress table when needs to.

i have tried:

(employeemap) hasmany(x => x.addresses).table("employeeaddress").keycolumn("employeeid"); 

but nhibernate complained address class did not have own mapping class.

(addressmap) id(x => x.id); map(x => x.parentitemid);  //generic way reference employeeid or customerid                            // can't specify column name should                             //  using 

but nhibernate tried grabbing data out of address table doesn't exist, , column names wrong.

fyi: not able combine 2 address tables one.

you can create mappings inherit each other

base mapping class contains duplicated values:

public class addressbasemap<t> : classmap<t> t : address {     public addressbasemap()     {         map(x => x.address);         //etc     } }   public class customeraddressmap : addressbasemap<customeraddress> {     public customeraddressmap()     {         table("customeraddress");     } } 

i suggest use of components can encapsulate of fields single class.
