Taking matrix for example, in each type of Matrix I have defined an add
add_row method which accepts a row which would be of the same kind(
DnaSeqMatrix will take DnaSeqRow ) :
def add_row( row )
raise InvalidRowException, "DnaSeqRow expected." unless
row.instance_of? DnaSeqRow
row_set[ row.id ] = row
end
If instead I define a add_row method in SeqMatrix like this:
def add_row( row )
# a DnaSeqMatrix will take a DnaSeqRow
type = self.class.to_s.sub( /Matrix/, 'Row' )
klass = NeXML.const_get( type )
raise InvalidRowException, "#{type} expected." unless row.instance_of?
klass
end
This way I won't have to define add_row for each sub type of SeqRow.
Similarly for others.
