mail::account::findFolder — A direct short-cut to a folder


#include <libmail/mail.H>

class myCallback : public mail::callback {
    void success(std::string msg);
    void fail(std::string msg);
class myFolderCallback : public mail::callback::folderlist {
    void success(const std::vector<const mail::folder *> &folders);
mail::account *account;

mail::folder *folder;

std::string folderPath=folder->getPath();

mail::folder *folder=account->findFolder(std::string folderPath, myFolderCallback &folderCallback, myCallback &callback);


This function is very similar to mail::account::folderFromString(3x). mail::account::findFolder recreates a mail::folder object, given its server path (which is returned by mail::folder::getPath(3x). The differences between mail::account::findFolder and mail::account::folderFromString are:

· mail::account::folderFromString uses a string created by mail::account::folder::toString, which includes all of the folder's properties (such as whether the folder contains messages, subfolders, or both, and its canonical name). mail::account::findFolder uses only the folder's "path", or "address" on the server.


The application must not destroy folderCallback until this request fails or succeeds. folderCallback's success method is invoked just before the callback's success method.

The folderCallback.success method receives a vector with a single pointer mail::folder object, that's initialized to represent the folder referenced by folderPath.

Return Codes and Callbacks

The application must wait until callback's success or fail method is invoked. The success method is invoked when this request is succesfully processed. The fail method is invoked if this request cannot be processed. The application must not destroy callback until either the success or fail method is invoked.


callback's fail method may be invoked even after other callback methods were invoked. This indicates that the request was partially completed before the error was encountered.


The folderCallback.success method receives a (possibly empty) vector of pointers to mail::folder objects. These objects will be destroyed when folderCallback.success terminates. The application must use mail::folder::clone(3x) to create copies of mail::folder objects it wants to use later.


Both folderCallback.success and myCallback.success method will be invoked if this request succeeds. folderCallback.success will be invoked before myCallback.success (since by definition this indicates that the request has been completed).


mail::folders are linked to their corresponding mail::accounts. A mail::folder created by one mail::account may not be used with a different mail::folder. All mail::folders created by a mail::account are invalidated when this mail::account object is destroyed. Note that the mail::folder objects are not automatically destroyed; the application is still responsible for destroying any remaining mail::folders, after their a mail::account is destroyed.
