Like all OsidLists, CredentialList provides a means for accessing Credential elements sequentially either one at a time or many at a time. Examples:

                     
                     
                     while (cl.hasNext()) {
                          Credential credential = cl.getNextCredential();
                     }
                     
                                 
                     
                

                     
                     
                     while (cl.hasNext()) {
                          Credential[] credentials = cl.getNextCredentials(cl.available());
                     }
