def gap_char
  ((defined? @gap_char) ? @gap_char : nil) or GAP_CHAR
end

- (Object) gap_regexp

Returns regular expression for checking gap.

end

- (Object) missing_char

Character if the site is missing or unknown.

def missing_char
  ((defined? @missing_char) ? @missing_char : nil) or MISSING_CHAR
end

- (Object) seqclass

Returns class of the sequence. If instance variable @seqclass (which can be set by 'seqclass=' method) is set, simply returns the value. Otherwise, returns the first sequence's class. If no sequences are found, returns nil.

  end

    ret[:seqclass] = @seqclass
  end
  ret
end

- (Boolean) is_gap?(s)

If given character is a gap, returns true. Otherwise, return false. Note that s must be a String which contain a single character.

Returns:

  • (Boolean)

  (gap_regexp =~ s) ? true : false
end

- (Object) set_all_property(hash)

Sets properties from given hash. hash would be a return value of get_character method.
