- RowSource
class RowSource |
|
Wraps the C cursor object in a python iterable object
This object keeps its own copy of the iterator position and explicitly calls scroll()
on the cursor for each request; This allows multiple RowSource objects
to work on the same cursor without conflicting;
The extra scroll() method should not slow mysql down significantly.
In most cases, we would already be on the specified row and as such
the scroll() call would be ignored. |

Methods defined here:
- __getitem__(self, item)
- Returns the specified row
int => {}
- __getslice__(self, start, end)
- Return a new RowSource that iterates only over the specified slice
If self has already been sliced, return a slice of that slice
i,j => [i:j]
- __init__(self, cursor, start=0, limit=None, position=0)
- __iter__(self)
- Returns a new instance of RowSource
If we have previously been 'sliced' (i.e. result[100:200] )
the resulting iterator will also only iterate over that slice
(Multiple instances of RowSource can safely be used without conflicts on the same cursor)
- __len__(self)
- buildDict(self, row)
- Builds a dictionary out of the specified row, based on self.fields (The query description from the cursor)
() => {}
- describe(self)
- Returns resultset field information
- next(self)
- Seeks to the correct row, builds a dictionary of key=>value pairs, and returns it
- seek(self, row)
- Lazily seeks to the specified row
Data and other attributes defined here:
- __ac_permissions__ = ()
- __allow_access_to_unprotected_subobjects__ = 1
