22 """Module for query operations
26 - Add field definitions
27 - See how L{NODE_FIELDS} is built
29 - Query field definition (L{objects.QueryFieldDefinition}, use
30 L{_MakeField} for creating), containing:
31 - Name, must be lowercase and match L{FIELD_NAME_RE}
32 - Title for tables, must not contain whitespace and match
34 - Value data type, e.g. L{constants.QFT_NUMBER}
35 - Human-readable description, must not end with punctuation or
37 - Data request type, see e.g. C{NQ_*}
38 - OR-ed flags, see C{QFF_*}
39 - A retrieval function, see L{Query.__init__} for description
40 - Pass list of fields through L{_PrepareFieldList} for preparation and
42 - Instantiate L{Query} with prepared field list definition and selected fields
43 - Call L{Query.RequestedData} to determine what data to collect/compute
44 - Call L{Query.Query} or L{Query.OldStyleQuery} with collected data and use
46 - Data container must support iteration using C{__iter__}
47 - Items are passed to retrieval functions and can have any format
48 - Call L{Query.GetFields} to get list of definitions for selected fields
50 @attention: Retrieval functions must be idempotent. They can be called multiple
51 times, in any order and any number of times.
