reduce the number of different file accesses and reduce the amount of |

AT THIS TIME THE USE OF THIS FUNCTION IS *NOT* RECOMMENDED |
|
|
|
Use lonnavmaps to build a data structure describing the order and |
|
assessment contents of each sequence in the current course. |
|
|
|
The returned structure is a hash reference. |
|
|

parts => [11,13,15], # only for assessment |
|
response_ids => [12,14,16], # only for assessment |
|
contents => [........] # only for container |
|
} |
|
|
|
$hash->{'contents'} is a reference to an array of hashes of the same structure. |
|
|
|
Also returned are array references to the sequences and assessments contained |
|
in the course. |

|
HISTORY: This function originally existed in every statistics module, |
|
and performed different tasks, the had some overlap. Due to the need |
|
for the data from the different modules, they were combined into |
|
a single function. |
|
|
|
This function now extracts all the necessary course data for a student |
|
from what was downloaded from their homeserver. There is some extra |
|
time overhead compared to the ProcessStudentInformation function, but |
|
it would have had to occurred at some point anyways. This is now |
|
typically called while downloading the data it will process. It is |
|
the brother function to ProcessStudentInformation. |
|

Input: $input, $output, $data, $name |
|
|
|
$input: A hash that contains the input data to be processed |
|
|
|
$output: A hash to contain the processed data |
|
|
|
$data: A hash containing the information on what is to be |
|
processed and how (basically). |
|
|
|
$name: username:domain |
|
|
|
The input is slightly different here, but is quite simple. |
|
It is currently used where the $input, $output, and $data |
|
can and are often the same hashes, but they do not need |
|
to be. |
|
|
|
Output: None |
|
|
|
*NOTE: There is no output, but an error message is stored away in the cache |
|
data. This is checked in &FormatStudentData(). The key username:domain:error |
|
will only exist if an error occured. The error is an error from |
|
&DownloadCourseInformation(). |

|
Retrieve the current status of a students performance. $sname and |
|
$sdom are the only required parameters. If $symb is undef the results |
|
of an &Apache::lonnet::currentdump() will be returned. |
|
If $courseid is undef it will be retrieved from the environment. |
|
|
|
The return structure is based on &Apache::lonnet::currentdump. If |
|
$symb is unspecified, all the students data is returned in a hash of |
|
the form: |
|
( |
|
symb1 => { param1 => value1, param2 => value2 ... }, |
|
symb2 => { param1 => value1, param2 => value2 ... }, |
|
) |
|
|
|
If $symb is specified, a hash of |
|
( |
|
param1 => value1, |
|
param2 => value2, |
|
) |
|
is returned. |
|
|
|
If no data is found for $symb, or if the student has not performance data, |
|
an empty list is returned. |
