member
|
The member function searches the List argument {list} for the match of
the search object argument {obj} and returns the index where {obj}
was found. If the {obj} was not found, false is returned. The member
function uses the isEqual predicate.
The member function is used to find an object {obj} in a List {list}. Since the member function returns the location of the {obj}, the member function makes it convenient to perform some operation on the {obj} . An alternate function, the isMember function, is used when a Boolean value of either true or false is sufficient.
(member obj list) Returns false if the object is not present. Returns an integer representing the index
into the List where the object was found.
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.
