Sample Applications
The PayPal SDK includes sample applications in the SDK_root/samples directory. Each
subdirectory comes with a README file that explains how to set up the application.
EWPProfile interface This interface defines the basic information that PayPal needs to
know about a user of PayPal’s Encrypted Website Payments (EWP)
service. Developers must create an instance of EWPProfile for each
account that generates the encrypted button code; for single-merchant
users this will just be a single instance). PayPal provides a basic
implementation class called DefaultEWPProfile suitable for the needs
of most SDK developers. However, you are free to write a custom
implementation if you need functionality the default class does not
offer.
ProfileFactory class This class creates both APIProfile and EWPProfile objects. It
contains static methods that handle the instantiation and construction
of profile objects.
Profiles class This data class represents all profiles the SDK knows about. It
contains two collections, one for APIProfiles and one for
EWPProfiles. This class is provided to ProfileHandler to save profile
data and returned from ProfileHandler to retrieve profile data.
