Macaulay2Doc :: MutableList

MutableList -- the class of all mutable lists

Description

For an overview of lists and sequences, see lists and sequences.

Normally the entries in a mutable list are not printed, to prevent infinite loops in the printing routines. To print them out, use peek.

i1 : s = new MutableList from {a,b,c};

i2 : s#2 = 1234;

i3 : s

o3 = MutableList{...3...}

o3 : MutableList

i4 : peek s

o4 = MutableList{a, b, 1234}
