Internal use. An implementation of Eratosthenes’ sieve
The error type thrown by all PStore methods.
Indicates a failure to resolve a name or address.
A parent has children, and has methods for accessing them. The Parent class is never encountered except as the superclass for some other object.
You don’t want to use this class. Really. Use XPath, which is a wrapper for this class. Believe me. You don’t want to poke around in here. There is strange, dark magic at work in this code. Beware. Go back! Go back while you still can!
Rinda error base class
Raised when trying to use a canceled tuple.
Raised when trying to use an expired tuple.
The basic error all other RSS errors stem from. Rescue this error if you want to handle any given RSS error and you don’t care about the details.
RSS, being an XML-based format, has namespace support. If two namespaces are declared with the same name, an OverlappedPrefixError will be raised.
The InvalidRSSError error is the base class for a variety of errors related to a poorly-formed RSS feed. Rescue this error if you only care that a file could be invalid, but don’t care how it is invalid.
Since RSS is based on XML, it must have opening and closing tags that match. If they don’t, a MissingTagError will be raised.
Some tags must only exist a specific number of times in a given RSS feed. If a feed has too many occurrences of one of these tags, a TooMuchTagError will be raised.
Certain attributes are required on specific tags in an RSS feed. If a feed is missing one of these attributes, a MissingAttributeError is raised.
RSS does not allow for free-form tag names, so if an RSS feed contains a tag that we don’t know about, an UnknownTagError is raised.
Raised when an unexpected tag is encountered.
