|
|
Determine the problem parts or responses preceeding and following the |

current resource. |

Inputs: $target (see &Apache::lonstathelpers::get_target_from_id()) |
|
$AcceptableResponseTypes, regular expression matching acceptable |

response types, |

$granularity, either 'part' or 'response' |

Returns: three hash references, $prev, $curr, $next, which refer to the |

preceeding, current, or following problem parts or responses, depending |

on the value of $granularity. Values of undef indicate there is no |
|
previous or next part/response. A value of undef for all three indicates |
|
there was no match found to the current part/resource. |

|
The hash references contain the following keys: |

If $granularity eq 'response', the following ADDITIONAL keys will be present: |
