How to set component access to add/update/display in PeopleCode?

In people code, how to set the component access level to Add/Update/Display from read only.

Example:

When the user accesses the Page1 through the Page2, the peoplecode will validate if the user has Update/Correct access to the Page1 through the delivered menu

1) If the user has Update/Correct access, the component’s mode will be updated to Update/Correct

2) If the user doesn’t have Update/Correct, the component’s mode will stay as read-only
