  Appends a String representation of this object which includes its class name, its object address and the values of all instance variables.

• #matches?(id : Char) : Bool

  Returns true if the chain id equals the given character, else false.

• #matches?(ids : Enumerable(Char)) : Bool

  Returns true if the chain id is included in the given characters, else false.

• #polymer? : Bool
• #renumber_residues_by(& : Residue -> _) : Nil

  Renumber residues based on the order by the output value of the block.

• #renumber_residues_by_connectivity : Nil

  Renumber residues based on bond information.

• #reset_cache : Nil
• #residues : ResidueView
• #spec(io : IO) : Nil

  Writes the chain specification to the given IO.

• #spec : String

  Returns the chain specification.

• #structure : Structure
• #structure(*args, **options)

  TODO remove this nonsensical line

• #structure(*args, **options, &)

  TODO remove this nonsensical line

• #to_s(io : IO)

  Appends a short String representation of this object which includes its class name and its object address.
