VisibleList -- class of all visible lists

VisibleList -- class of all visible lists

There are three types of lists that can be entered directly from the keyboard, as follows.

i1 : {a,b,c}



o1 = {a, b, c}



o1 : List

i2 : [a,b,c]



o2 = [a, b, c]



o2 : Array

i3 : (a,b,c)



o3 = (a, b, c)



o3 : Sequence

We introduce the class of visible lists as a convenience for referring to lists of these types.

The type VisibleList is a member of the class Type. Each object of class VisibleList is called a visible list. Each visible list is also a member of class BasicList.

Types of VisibleList :

Array -- class of all arrays -- [...]

List -- class of all lists -- {...}

Sequence -- class of all sequences -- (...)

Making a visible list :

Function \ VisibleList -- apply a function to each member of a list

VisibleList / Function -- apply a function to each member of a list

accumulate(Function,Thing,VisibleList) -- apply binary operator repeatedly

accumulate(Function,VisibleList) -- apply binary operator repeatedly

accumulate(VisibleList,Function) -- apply binary operator repeatedly

accumulate(VisibleList,Thing,Function) -- apply binary operator repeatedly

flatten VisibleList

fold(Function,Thing,VisibleList) -- apply binary operator repeatedly

fold(Function,VisibleList) -- apply binary operator repeatedly

fold(VisibleList,Function) -- apply binary operator repeatedly

fold(VisibleList,Thing,Function) -- apply binary operator repeatedly

Methods for using a visible list :
