Hi,
Kind of new to this, two questions if anyone can help:
1) I want to make some class that is persistent on the data store. I
can use a primary key of either Long or String. It would be more
convenient for me to use String as the primary key. Is this going to
really hurt performance-wise when doing lookups for objects vs a Long?
2) I have some objects which are somewhat large, like:
public class Story {
private String mId;
private String mTitle;
private String mFullText; <-- large
}
if I want to get a list of Story items, I don't want to spend time
loading the mFullText parameter on each one. I can hold off on loading
that until a user wants to see the full story. Is there a way to
implement two different load methods for Story to control this? Or do
we simply break a class like this up into two separate classes:
public class StoryDescription {
private String mId;
private String mTitle;
}
public class StoryText {
private String mId;
private String mFullText;
}
and load as needed?
Thanks
