Detailed Description
Helper methods that store data in a file instead of the database.
- Todo
- Use exceptions for error handling in all these methods. Requires that all callers can handle that first though.
Function Documentation
◆ insert()
bool Akonadi::Server::PartHelper::insert | ( | Part * | part, |
qint64 * | insertId = nullptr ) |
Adds a new part to the database and if necessary to the filesystem.
part
must not be in the database yet (ie. valid() == false) and must have a data size set.
Definition at line 58 of file parthelper.cpp.
◆ remove() [1/2]
Deletes all parts which match the given constraint, including all corresponding filesystem data.
Definition at line 102 of file parthelper.cpp.
◆ remove() [2/2]
bool Akonadi::Server::PartHelper::remove | ( | Part * | part | ) |
Deletes part
from the database and also removes existing filesystem data if needed.
Definition at line 90 of file parthelper.cpp.
◆ translateData() [1/2]
QByteArray Akonadi::Server::PartHelper::translateData | ( | const Part & | part | ) |
Convenience overload of the above.
Definition at line 147 of file parthelper.cpp.
◆ translateData() [2/2]
QByteArray Akonadi::Server::PartHelper::translateData | ( | const QByteArray & | data, |
Part::Storage | storageType ) |
Returns the payload data.
Definition at line 122 of file parthelper.cpp.
◆ truncate()
bool Akonadi::Server::PartHelper::truncate | ( | Part & | part | ) |
Truncate the payload of part
and update filesystem/database accordingly.
This is more efficient than using update since it does not require the data to be loaded.
Definition at line 152 of file parthelper.cpp.
◆ update()
void Akonadi::Server::PartHelper::update | ( | Part * | part, |
const QByteArray & | data, | ||
qint64 | dataSize ) |
Update payload of an existing part part
to data
and size dataSize
.
Automatically decides whether or not the data should be stored in the database or the file system.
- Exceptions
-
PartHelperException if file operations failed
Definition at line 22 of file parthelper.cpp.
◆ verify()
bool Akonadi::Server::PartHelper::verify | ( | Part & | part | ) |
Verifies and if necessary fixes the external reference of this part.
Definition at line 164 of file parthelper.cpp.
