Bio::Symbol::AlphabetI - A Symbol Alphabet


    # get a Bio::Symbol::AlphabetI object somehow
    my @symbols = $alphabet->symbols;
    my @subalphas = $alphabet->alphabets;
    if( $alphabet->contains($symbol) ) {
        # do something


Alphabet contains set of symbols, which can be concatenated to form symbol lists. Sequence string, for example, is stringified representation of the symbol list (tokens of symbols).

This module was implemented for the purposes of meeting the BSANE/BioCORBA spec 0.3 only.
