member
|
The member function takes a key as an argument and a Structure as a second argument and returns the index where the key was found. If the key was not found,
the member function returns false. The member
function uses the isEqual predicate.
Use the member function if you want to locate the position of a certain member (key) in a Structure object. If you just want to know if a member is in the Structure but do not care where it is located if it is found, use the isMember function, which returns a Boolean true or false.
(member key struct) Returns the index of the member if it is found, otherwise it returns false.
Here are a number of links to Lambda coding examples which contain this instruction in various use cases.
Here are the links to the data types of the function arguments. Here are also a number of links to functions having arguments with any of these data types.
