#X text 37 165 This library was made for algorithmic composition and
of course for all other algorithms. I came into troubles with making
bigger musical structures in PD with send-receive pairs \, arrays \,
etc. So I tried to make it possible \, to have access to some storage
in a whole patch.;
#X text 131 131 ::: GOAL OF THE LIBRARY :::;
#X text 39 428 For communication I use namespaces. Every Container
with the same namespace (and the same container type) has access to
the same data. So you can modify and get this data everywhere in the
patch. For local namespaces use names with \$0.;

#X text 254 23 general explation of;
#X text 254 40 the datastructures;
#X text 23 655 A vector is a sequence that supports access to all elements
via index (like an array) and fast insertion and removal of elements
at the end. The number of elements in a vector may vary dynamically.
;
#X obj 189 627 h_vector;
#X text 500 654 Fast insertion and removal anywhere \, all the other
elements move up. But a list provides only sequential access (not via
index !). A list is a doubly linked list.;
#X obj 680 628 h_list;
#X obj 189 773 h_deque;
#X text 498 801 A queue is a "first in first out" (FIFO) data structure.
That is \, elements are added to the back of the queue (push) and may
be removed from the front (pop).;
#X obj 679 774 h_queue;
#X text 22 951 A priority queue is also a "first in first out" (FIFO)
data structure \, but you can give the elements a priority. So the
elements with a higher priority are automatically inserted before all
other elements with a lower priority.;
#X obj 154 924 h_priority_queue;
#X text 20 800 A deque (double ended queue \, pronounced "deck") is
very much like a vector: like vector \, it is a sequence that supports
access to all elements via index. The main way in which deque differs
from vector is that fast insertion and removal of elements is possible
at the beginning _and_ the end.;
#X text 22 232 Maps represent a mapping from one type (the key type)
to another type (the value type). You can associate a value with a
key \, or find the value associated with a key \, very efficiently.
Map is a Sorted Associative Container and it is also a Unique Associative
Container \, meaning that no two elements have the same key. (see Multimap
for more elements with the same key);
#X obj 188 203 h_map;
#X text 492 231 Multimaps are just like maps except that a key can
be associated with several values. Multimap is a Sorted Associative
Container and also a Multiple Associative Container \, meaning that
there is no limit on the number of elements with the same key. (see
also Map);
#X obj 643 201 h_multimap;
#X text 24 419 Sets allow you to add and delete elements. Afterwards
you can look if an element is set. Set is a Sorted Associative Container
and a Unique Associative Container \, meaning that no two elements
are the same. (see Multiset to have several copies of the same element)

#X obj 187 392 h_set;
#X text 493 419 Multisets are just like sets \, except that you can

Container and a Multiple Associative Container \, meaning that two

#X text 495 950 Stack is a "last in first out" (LIFO) data structure:
the element at the top of a stack is the one that was most recently
added (push). Top outputs the elements from the top without removing
it \, pop outputs and removes it.;
