VisibleList -- the class of all visible lists

VisibleList -- the class of all visible lists

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.

More general types (whose methods may also apply) :

BasicList -- the class of all basic lists

Types of visible list :

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

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

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

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.

Functions and methods returning a a visible 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

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

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

VisibleList _ {...} -- get some entries of a list

Methods for using a visible list :

between(Thing,VisibleList)

member(Thing,VisibleList)

position(VisibleList,Function)

positions(VisibleList,Function)
