dip.io.storage¶
The dip.io.storage module implements support for specific storage types.
QIODeviceStorage¶
- class dip.io.storage.QIODeviceStorage¶
Base class: Model
The QIODeviceStorage class is an abstract base class for storage that is accessed via a QIODevice.
- read_buffer_size = Int(16384)
- The number of bytes to read at a time.
- implicit_location(obj)¶
Return the implicit storage location for an object.
Parameter: obj – is the object to create the location for. Returns: None as devices typically have explicit locations.
- qiodevice(location)¶
A storage location is converted to a QIODevice instance. This must be reimplemented by a sub-class.
Parameter: location – is the storage location. Returns: the QIODevice.
- read(obj, location)¶
Read an object from a storage location.
Parameters: - obj – is the object to populate from the storage location.
- location – is the storage location where the object is read from.
Returns: the read object. This may be the original object populated from the storage location, or it may be a different object (of an appropriate type) created from the storage location.
- write(obj, location)¶
Write an object to a filesystem location.
Parameters: - obj – is the object to write.
- location – is the storage location where the object is written to.
