New Features

PST file traversal API

The traversal API allows extracting all PST items as far as possible, without throwing out exceptions, even if some data of the original file is corrupted.

The following steps show how to use this API.

Use PersonalStorage(TraversalExceptionsCallback callback) constructor and load(String fileName) method instead of fromFile method.

The constructor allows defining a callback method.

TraversalExceptionsCallback exceptionsCallback = new TraversalExceptionsCallback() {
    @Override
    public void invoke(TraversalAsposeException exception, String itemId) {
        /* Exception handling  code. */
    }
};

try (PersonalStorage pst = new PersonalStorage(exceptionsCallback)) { }

Loading and traversal exceptions will be available through the callback method.

The load method returns 'true' if the file has been loaded successfully and further traversal is possible. If a file is corrupted and no traversal is possible, 'false' is returned.

if (currentPst.load(inputStream))

Code example

public static void main(String[] args) {
    TraversalExceptionsCallback exceptionsCallback = new TraversalExceptionsCallback() {
        @Override
        public void invoke(TraversalAsposeException exception, String itemId) {
            /* Exception handling  code. */
        }
    };

    try (PersonalStorage pst = new PersonalStorage(exceptionsCallback)) {
        if (pst.load("test.pst")) {
            getAllMessages(pst, pst.getRootFolder());
        }
    }
}

private static void getAllMessages(PersonalStorage pst, FolderInfo folder) {
    for (String messageEntryId : folder.enumerateMessagesEntryId()) {
        MapiMessage message = pst.extractMessage(messageEntryId);
    }
    for (FolderInfo subFolder : folder.getSubFolders()) {
        getAllMessages(pst, subFolder);
    }
}

Custom search by message fields with ImapClient

Gmail has an IMAP Extension that implements the search:

AE_1_1_0034 SEARCH X-GM-RAW "has:attachment"
* SEARCH 1 3 5 7 9
AE_1_1_0034 OK SEARCH completed (Success)

The customSearch method has been added to ImapQueryBuilder.

ImapQueryBuilder builder = new ImapQueryBuilder();
builder.customSearch("X-GM-RAW \"has:attachment\"");
MailQuery query = builder.getQuery();
messageInfoCol = client.listMessages(query);

LocaleOptions type specifies locale configuration for Aspose.Email.

We can use LocaleOptions.setLocale in case of unrecognised default locale and set most appropriate locale for Aspose Email lib

Methods:

Returns default Locale for Aspose.Email.

public static Locale getLocale()

Set default locale related for Aspose.Email.

public static void setLocale(Locale locale)
public static void setLocale(String localeName)

Clears default locale for Aspose.Email. Will be used locale default for Java.

public static void clear()

Code example

final Locale locale = new Locale("en", "DE");
Locale.setDefault(locale);

// set Locale for Aspose Email lib
LocaleOptions.setLocale("en-US");
// or
//LocaleOptions.setLocale(new Locale("en", "US"));

MailMessage.load("document.msg");
