=item &get_sequence_assessment_data() |
|
|
|
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. |
|
|
|
{ title => 'title', |
|
symb => 'symb', |
|
src => '/s/o/u/r/c/e', |
|
type => (container|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. |
