PHP Paypal REST Billing Agreement combined with Digital Item -

-

in paypal sandbox, when create billing plan & agreement setup_fee, user can complete billing process paypal , plan created if user's paypal account has no funds available.

it appears setup_fee can take minutes after creation of plan & agreement until charges account.

i know classic digital goods api it's suggested combine billing plan checkout digital goods item, user have authorize payment digital goods item & billing agreement together. way user can create billing profile if able pay digital goods item. still best practice? if so, how using new rest php sdk?

is viable way it?:

  1. set plan when user starts checkout first billing amount being discounted price

  2. set billing agreement user authorise start date in hour

  3. list item once first payment cleared, run cron job update plan amount undiscounted rate next month's billing

seems unbelievably complicated me can't see other way without forcing user authenticate twice (once authorise payment, once authorise billing agreement)

this helpful paypal rest api discussion

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
