Method Details

refresh

public void refresh()

Refreshes the grid by updating the list of current users and their matches. This method clears the current user list and user match map, and then iterates through the active users. For each active user, it checks if their current location falls within the specified latitude and longitude bounds. If a user's location is within the bounds, they are added to the current user list and a new empty list is created for their matches. Finally, it iterates through the current user list and checks for matches between users based on their filters. If a match is found, it inserts the users into each other's match lists.
