Thanks for your response, Fabio. Your suggestion means, that I should define the generator parameter in User mapping definition "block" (which is placed in a ClassMapping class in some other assembly in my case - modular application) if I understand it right. This isn't solution I can accept, because it decentralizes the responsibility for generator configuration (at least part of it) and it'd be PITA to move to another generator strategy. I can workaround it of course, but I think the possibility to retrieve actual class mapping configuration in AfterClassMap would be quite meaningful in this and probably also other similar cases.

Filip,
in the same way you apply the table name in BeforeClassMap you can apply the generatos parameters/restrictions.
In the same place where you override your TableNaming convention you can override the generatos parameters/restrictions.

Ricardo, you have to use the auto-quote configuration and that is all.

This is just one sample case.. I can figure out some other example - what if table name length is limited to 30 characters (Oracle) and my entity name is longer etc. The same could be with column names for some other post-processing etc. I think it's fully meaningful to have some mean to access entity mapping metadata in AfterMapClass event. I could build some massive convention algorithm to produce table names (plurals + shorten long table names with short name collision handling etc.), but KISS + there can always be some exception.

Not directly related, but for the table or the column names, you should always use the syntax `USER`, where the ` gets translated to the DB-specific escape character.

I was looking for any possibility how to retrieve some attributes of mapped class (= HbmClass instance) being processed in AfterMapClass event for further processing, but the ClassMapper.classMapping field is unfortunately not publicly accessible. There should be public read-only property defined for this field. My particular use-case is I need to retrieve table name defined for the class to use it in table based HighLow generator for Id field of mapped entity-classes:
modelMapper.AfterMapClass += (mi, t, map) =>
{
map.Id(x =>
{
var tableName = ???;
x.Column("ID");
x.Generator(Generators.HighLow, gm => gm.Params(new { where = String.Format("TABLENAME = '{0}'", tableName) }));
});
}
