Apache::lonwishlist - Wishlist-Module |
|
|
|
=head1 SYNOPSIS |
|
|
|
The wishlist offers a possibility to store links to resources from the resource-pool and external websites in a hierarchical list. |
|
It is only available for user with access to the resource-pool. The list can be structured by folders. |
|
|
|
The wishlist-module uses the CPAN-module "Tree" for easily handling the directory-structure of the wishlist. Each node in the tree has an index to be referenced by. |

Searches for a node, specified by the index, in nodes (reference to array) and returns it. |

Moves a given node to a new parent (if new parents is defined) or change the position from a node within its siblings (means sorting, at must be defined). |

Removes a node given by node from the tree. |

Sets an index for every node in the tree, beginning with 0. |

Recursive call starting with all children of the root of the tree (parameter children is reference to an array containing the nodes of the current level). |

Resets index counter. |
