}

But it shows errors on "M entityModel".

I don´t know why...

Can you please help me find out, why it´s wrong?

You never define the M type parameter

somewhere else it looks like it´s the basic type for models, like "T" is the basic for EitityTypes.

Do some research in Java generics. The name T is just convention the same way as it is convention to use i as a loop variable
