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. =head1 FEEDBACK =head2 Mailing Lists User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated. bioperl-l@bioperl.org - General discussion http://bioperl.org/MailList.shtml - About the mailing lists =head2 Reporting Bugs Report bugs to the Bioperl bug tracking system to help us keep track of the bugs and their resolution.

Internal methods are usually preceded with a _ =cut # Let the code begin... package Bio::Symbol::AlphabetI; use strict; use Bio::Root::RootI; =head2 AlphabetI Interface methods =cut =head2 symbols Title : symbols Usage : my @symbols = $alphabet->symbols(); Function: Get/Set Symbol list for an alphabet List of symbols, which make up this alphabet. Returns : Array of L<Bio::Symbol::SymbolI> objects Args : (optional) Array of L<Bio::Symbol::SymbolI> objects =cut sub symbols{ my ($self,@args) = @_; $self->throw_not_implemented(); } =head2 alphabets Title : alphabets Usage : my @alphabets = $alphabet->alphabets(); Function: Get/Set Sub Alphabet list for an alphabet Sub-alphabets. E.g. codons made from DNAxDNAxDNA alphabets Returns : Array of L<Bio::Symbol::AlphabetI> objects Args : (optional) Array of L<Bio::Symbol::AlphabetI> objects =cut sub alphabets{ my ($self,@args) = @_; $self->throw_not_implemented(); } =head2 contains Title : contains Usage : if($alphabet->contains($symbol)) { } Function: Tests of Symbol is contained in this alphabet Returns : Boolean Args : L<Bio::Symbol::SymbolI> =cut sub contains{ my ($self,@args) = @_; $self->throw_not_implemented(); } # Other methods from BSANE - not sure if we will implement here or only in # BioCORBA implementation # Resolve symbols from the token string. # SymbolList to_symbol(in string tokens) raises ( IllegalSymbolException) ; # Convinience method, which returns gap symbol that do not # match with any other symbols in the alphabet. # Symbol get_gap_symbol() raises ( DoesNotExist) ; # Returns a ambiguity symbol, which represent list of # symbols. All symbols in a list must be members of # this alphabet otherwise IllegalSymbolException is # thrown. # Symbol get_ambiguity( in SymbolList symbols) raises( IllegalSymbolException); # Returns a Symbol, which represents ordered list of symbols # given as a parameter. Each symbol in the list must be member of # different sub-alphabet in the order defined by the alphabets # attribute. For example, codons can be represented by a compound # Alphabet of three DNA Alphabets, in which case the get_symbol( # SymbolList[ a,g,t]) method of the Alphabet returns Symbol for # the codon agt.<p> # IllegalSymbolException is raised if members of symbols # are not Symbols over the alphabet defined by # get_alphabets()-method # Symbol get_symbol(in SymbolList symbols) raises(IllegalSymbolException) ; 1;
