Free NHibernate, dynamically changes the mapping table?

Question

with smooth nhibernate, is there a way to dynamically switch the mapping table at runtime?

For instance:

public class XYClassMap : ClassMap<XY>
{
  public XYClassMap( )
  {
    Table("XYTable");
    Id(d => d.Id).GeneratedBy.Identity();
    Map(d => d.Value);
    (...)

Given that there are several plugins, each of them uses this one class, but they need to work with different tables. I am looking for something like this:

public class XY {
  public string Tablename {get; set;}
}

public class XYClassMap : ClassMap<XY>
{
  public XYClassMap( )
  {
    Table(Tablename);
    Id(d => d.Id).GeneratedBy.Identity();
    Map(d => d.Value);
    (...)

Thus, each action method can work with the same class, and only he will need to set this property to “Table Name”.

Thanks for any help

Mappings are compiled at application startup, and after that they cannot be changed.

public abstract class PluginMap<T> : ClassMap<T> where T : IPlugin
{
  public PluginMap()
  {
    Id(d => d.Id).GeneratedBy.Identity();
    Map(d => d.Value);
  }
}

public class PluginOneMap : PluginMap<PluginOne>
{
  public PluginOneMap()
  {
    Table("PluginOne");
  }
}

public class PluginTwoMap : PluginMap<PluginTwo>
{
  public PluginTwoMap()
  {
    Table("PluginTwo");
  }
}
