Method Details [hide private]

__init__(self, *args)
(Constructor)

source code 
All sync functionality should be provided by derived classes
Overrides: DataProvider.DataSink.__init__

initialize(self)

source code 

Called when the module is loaded by the module loader.

It is called in the main thread so should NOT block. It should perform simple tests to determine whether the dataprovider is applicable to the user and whether is should be presented to them. For example it may check if a specific piece of hardware is loaded, or check if a user has the specific piece of software installed with which it synchronizes.
Returns: bool
True if the module initialized correctly (is appropriate for the user), False otherwise
Overrides: DataProvider.DataProviderBase.initialize
(inherited documentation)

put(self, photo, overwrite, LUID=None)

source code 
Accepts a vfs file. Must be made local. I also store a md5 of the photos uri to check for duplicates
Overrides: DataProvider.DataSink.put

delete(self, LUID)

source code 
Deletes data with LUID.
Overrides: DataProvider.DataSink.delete
(inherited documentation)

get_input_conversion_args(self)

source code 
Provides a way to pass arguments to conversion functions. For example when transcoding a music file the dataprovider may return a dictionary specifying the conversion encoding, quality, etc
Returns:
a dict of conversion arguments
Overrides: DataProvider.DataProviderBase.get_input_conversion_args
(inherited documentation)
