toList HashTable -- convert to list

Synopsis:

Function: toList -- list of elements

Input:

an instance of class HashTable.

Output:

an instance of class List.

toList x -- provides a list of keys in the hash table x.

For a set, which is implemented as a hash table where only the keys are important, this is a reasonable operation. See also, keys, which does the same thing.

i1 : x = hashTable { a=>1, b=>2}



o1 = HashTable{a => 1}

               b => 2



o1 : HashTable

i2 : toList x



o2 = {a, b}



o2 : List
