ConPeek() Function

  • The conPeek() is used to retrieve a specific element from a container.
  • Syntax: anytype conPeek(container container, int number)
    • container - The container to return an element from.
    • number - The position of the element to return. Specify 1 to get the first element.
    • Return value: The element in the container at the position specified by the number parameter. The conPeek function automatically converts the peeked item into the expected return type.

Example 


 
 
static void JobConatinerExample1(Args _args)
{
    // container declaration and initialization with 2 values
    container conatinerName = ["Hello World", 1234]; 
    str charHolder; 
    // conPeek() function returns the value being held in a specific position in the container. 
    // (Note: It returns anyType)
    // Here printing 1st and 2nd values from conatinerName to info
    charHolder = conPeek(conatinerName, 1);
    info(strFmt("Container conPeek() values are
           :- %1, %2", charHolder, conPeek(conatinerName, 2)));
}

Output
