[Seqan-dev] Failed to create ticket on trac: concatenator iterator problems

[John Reid <j.reid@mail.cryst.bbk.ac.uk>]

My ticket was rejected as spam so I'm posting it here:

I think the difference between the end and the begin iterators of an 
infix in a ConcatenatorManyToOne object should equal the length. The 
length reports 4 which is correct. The difference does not equal 4. I'm 
using svn revision 10211.

    string_set_t seqs;
    appendValue( seqs, string_t( "ACGT" ) );
    concatenator_t concat( seqs );
    infix_t in( concat, 0, 4 );
    if( 4 != length( in ) ) throw std::logic_error( "length() not 
working." );
    if( difference( begin( in ), end( in ) ) != length( in ) ) throw 
std::logic_error( "difference() not working." );
    return 0;
}
