init(self, name, container=None)
(Constructor)

source code

Base class of your index handler.

Built-in index handlers will always inherit from this class but your own handlers don't need to as long as they implement a method named update() and taking the member as its unique parameter.

Parameters:

name (string) - an internal identifier used to reference the indexer.
container (object) - instance of a class implementing the dictionnary interface.

Overrides: object.__init__

store(self, key, value)

source code

Stores a value within the index container.

Parameters:

key (object) - used to reference of the indexed value.
value (object) - what is being indexed

load(self, key)

source code

Returns the value associated with the key as a set of one element. The set is empty of the key is not found.

Returns: set: an empty or a one item set referenced by the key

iload(self, key)

source code

Yields the value associated with the key as a set of one element. The set is empty of the key is not found.

Returns: set: an empty or a one item set referenced by the key

iterindex(self, func)

source code

Iterates through the keys of the container and apply for each one the provided func with the key and the data associated.

If you want to stop the iteration you can simply raise StopIteration from the function.

Parameters:

func (callable) - function applied to each element found in the container.

Returns: set

the result set after func has been applied

iiterindex(self, func)

source code

Iterates through the keys of the container and yields each result of applying the provided func with the key and the data associated.

If you want to stop the iteration you can simply raise StopIteration from the function.

Parameters:

func (callable) - function applied to each element found in the container.

Returns: set

the result set after func has been applied

keys(self)

source code

Return all the existing keys in the container as a list. Not all containers support that features and should therefore be used carefully.

Returns: list: the list of all the keys of the container
