Description
Returns an indexed array of structs mapped to a given field name.
Parameters
Return Type
String []
Returns an array of indexed structs.
Examples
Example Part 1 - Data for structs
Assume we have a CSV file containing a list of toys. There is a column for the toy name and another for the toys color.
name, color
Airplane, White
Bouncy Ball, Blue
Car, Red
Dog, Brown
Elephant, Gray
...Example Part 2 - Populating structs
With the given CSV data we can quickly populate an array of structs.
//define struct
struct _toy {
string name;
string color;
}
//create struct array and populate from csv
_toy [] toys = readFromCSVFile("toysList.csv", true);Example Part 3 - Mapping the struct array
Now that we have a list of structs we can map them to one of the fields.
toys = arrayStructMap(toys, "name"); //mapping each array element to the name field
return toys["Bouncy Ball"].color; //element can be retrieved by name now that is has been mappedResult: "Blue"
