isMember
|
The isMember function determines whether or not the specified object
{obj} is a member of the {target} Vector. If the {obj} is found, true is returned.
If {obj} is not found, false is returned. The isMember
function uses the isEqual predicate. When to use The isMember function is used to determine if an object is in the List
It returns a Boolean value true if found in the List or
false if not found. If the desired information is the index of the object,
then the member function should be used instead
(isMember obj list) Returns true if the object was found. Returns false if the object was not 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.
