Module helpers.vVector
Static methods for tables whose elements all have the same data type
Functions
| filter (t, fn_callback) | [[ TODO execute a test function on each item |
| sort (t, fn_compare) | TODO sort elements according to the specified function |
| merge (t1, t2) | merge two vectors, using the specified key to identify matching items used for joining a temporary/filtered set with the original note: t1 overwrites matches in t2 |
| match_by_key_value (t, key, val) | Match entry in an array (provide key + value) |
| count_checked (t) | count checked items ("checked" is key, value is boolean) TODO depricated, use match instead |
| get_selected_item (t) | return first item whose "checked" attribute is true TODO depricated, use match instead |
