dict_to_vector — Returns a get_keyword style vector of all items stored in the given dictionary.


vector dict_to_vector ( inout dict dictionary ,
in destructive any );


The function returns an array of all data stored in the given dictionary, every pair is represented as two consecutive element of the resulting array. Thus the dictionary of N pairs is converted into a vector of length 2N where keys are at positions 0, 2, 4, ..., 2N-1 and corresponding dependent data are at positions 1, 3, 5, ..., 2N. If keys are all scalars of same type then get_keyword function can be used to search in the resulting array.

If the destructive parameter is 1 or 2 then the function may avoid copying of keys and values to the resulting array by moving them out from the dictionary. This is faster but the dictionary will become empty at the end of operation. The destructive parameter equal to 1 does not have any effect if the dictionary is used as a value of more than one variable. Thus it is safe to make this parameter equal to 1 as soon as the variable passed to the function as dict is no longer in use after the function call and there's no need to inspect the whole program to check if other variables may be affected. The parameter equal to 2 ignores the presence of multiple variables so the operation may cause unexpected results in other fragments of code that share the dictionary.



The dictionary to scan.


Flag that indicates whether the dictionary can be cleaned during the operation (0 = never clean, 1 = only if there is no other variables, 2 = clean unconditionally).

Return Types

The function returns a vector of even length.
