        TransformFilterMaker

Take a list of basic filters and makes a filter that transforms the basic filter into a top-level filter. This is mostly useful for the implementation of mkFilter, which should only be needed for special cases or internal use by this library.

This object is useful for creating simple filters for services that use one URI and are specified by one Type (we expect most Types will fit this paradigm).

Creates a BasicServiceEndpoint object and apply the filter functions to it until one of them returns a value.

Instance Methods

__init__(self, filter_functions)
Initialize the filter maker's state

source code

getServiceEndpoints(self, yadis_url, service_element)
Returns an iterator of endpoint objects produced by the filter functions.

source code

applyFilters(self, endpoint)
Apply filter functions to an endpoint until one of them returns non-None.
