Overview

CalendarData parser.

This class parses the urn:ietf:params:xml:ns:caldavcalendar-data XML element, as defined in:

tools.ietf.org/html/rfc4791#section-9.6

This element is used in three distinct places in the caldav spec, but in this case, this element class only implements the calendar-data element as it appears in a DAV:prop element, in a calendar-query or calendar-multiget REPORT request.

Class Method Details

.xml_deserialize(reader) ⇒ Object

The deserialize method is called during xml parsing.

This method is called statictly, this is because in theory this method may be used as a type of constructor, or factory method.

Often you want to return an instance of the current class, but you are free to return other data as well.

You are responsible for advancing the reader to the next element. Not doing anything will result in a never-ending loop.

If you just want to skip parsing for this element altogether, you can just call reader.next

reader.parse_inner_tree will parse the entire sub-tree, and advance to the next element.

Parameters:

  • Reader —

    reader

Returns:

  • mixed
