Index Finder StringSet

Example Program

Example for using a Finder of an Index of a StringSet.

This example shows how to use the Finder class for an Index search. The Index was build for a given StringSet.

A tutorial about an index based finder for a StringSet.

1	#include <iostream>
2	#include <seqan/index.h>
3
4	using namespace seqan;
5
6	int main ()
7	{

First, we create a StringSet of 3 Strings.

8	StringSet< String<char> > mySet;
9	resize(mySet, 3);
10	mySet[0] = "tobeornottobe";
11	mySet[1] = "thebeeonthecomb";
12	mySet[2] = "beingjohnmalkovich";
13

Then we create an Index of our StringSet and a Finder of the Index.

14	Index< StringSet<String<char> > > myIndex(mySet);
15	Finder< Index<StringSet<String<char> > > > myFinder(myIndex);
16

Finally we search for the string "be" and output all occurences

17	::std::cout << "hit at ";
18	while (find(myFinder, "be"))
19	::std::cout << position(myFinder) << " ";
20	::std::cout << ::std::endl;
21
22	return 0;
23	}

Output

weese@tanne:~/seqan$ cd demos
weese@tanne:~/seqan/demos$ make index_find_stringset
weese@tanne:~/seqan/demos$ ./index_find_stringset
hit at < 0 , 11 > < 1 , 3 > < 2 , 0 > < 0 , 2 >
weese@tanne:~/seqan/demos$
