Line # Kind Name Docs
81 Method __init__ Undocumented
def initialize(self):

Initialize the component.

This method is called by Component.create to finish the initialization of a component.
Returnsa deferred called when a component is fully initialized (type: twisted.internet.defer.Deferred )
def supported_uri_schemes__get(self):

Retrieve the URI schemes supported by the provider, for each scheme there's a priority. Higher priority == 0 means the provider will always be used to read data from a given scheme.

This function is called by the MediaManager to know which media provider it has to use to access a specified URI. You should return a dict containing the uri scheme (such as 'file', 'cdda', ...) and its priority between 0 to 255 (0 being the topmost priority). The prority is used by the MediaManager to know which media provider it should use in case there are more than one who support the desired uri scheme. You might have for example a component which supports more than one scheme, but the support of one of them is not very efficient compared to what it could be. In this case you could modify its priority to tell the MediaManager that another component should be used instead of it to access this scheme.

example: { 'file': 0, 'smb': 10 }

# FIXME: this should be documented in the class docstring as a class # variable
def scannable_uri_schemes__get(self):

Retrieve the URI schemes that can be scanned by the media_scanner. Since media scanning can be an heavy and long task the MediaProvider developer can choose to make the media_scanner skip URIs with scheme not appearing in returned list.

By default the return value of this method corresponds to the keys of supported_uri_schemes__get return value.

def get_media_type(self, uri):
Same as blocking_get_media_type but without blocking (in theory). This method by default triggers a succeeded callback on a Twisted deferred, using blocking_get_media_type result.
Parametersurithe URI to analyze (type: elisa.core.media_uri.MediaUri )
Returns (type: twisted.internet.defer.Deferred )
def has_children_with_types(self, uri, media_types):
Same as _blocking_has_children_with_types but without blocking (in theory). This method by default triggers a succeeded callback on a Twisted deferred, using _blocking_has_children_with_types result.
Parametersurithe URI to scan (type: elisa.core.media_uri.MediaUri )
media_typesthe media_types to look for on the directory (type: list of strings )
Returns (type: twisted.internet.defer.Deferred )
def get_direct_children(self, uri, l):
Same as _blocking_get_direct_children but without blocking (in theory). This method by default triggers a succeeded callback on a Twisted deferred, using _blocking_get_direct_children result.
Parametersurithe URI to analyze (type: elisa.core.media_uri.MediaUri )
children_with_infoList where the children will be appended (type: list )
Returns (type: twisted.internet.defer.Deferred )
def get_real_uri(self, uri):
Returns the original uri (acesable) from a virtual uri representation.
Parametersurithe URI to validate (type: elisa.core.media_uri.MediaUri )
Returns (type: elisa.core.media_uri.MediaUri )
