Improvement: Support to ignore fields about auto-value-cursor

[gabrielittner]

You can use ColumnTypeAdapters that don't read or write anything to achieve this. Beyond that I have no plans to support ignoring fields.

Hi @gabrielittner,

I am trying to to follow the approach you suggested, but I am having issues with the types.

I have implemented a generic ColumnTypeAdapter:

public abstract class IgnoreColumnAdapter<T> implements ColumnTypeAdapter<T> {

    public final T fromCursor(Cursor cursor, String columnName) {
        return null;
    }
    public final void toContentValues(ContentValues values, String columnName, T value) {
    }
}

Having this class:

public class User {
    // Column needs to be ignored
    public abstract UserCredentials userCredentials();
}

I have to create an specific class IgnoreUserCredentialsAdapter extends IgnoreColumnAdapter<UserCredentials> to ensure the generated code in fromCursor() has the expected type.

We have many types we would like to ignore. Is there a way to achieve this without creating an specific type for each of them?

Thanks a lot!
