public class Reader extends structure5.AbstractIterator<Token>
Tokens. By default, the stream is constructed
from a structure.ReadStream, but the Reader may also be constructed
to read from a List. This allows the recursive implementation of
procedures.| Constructor and Description |

Reader()
Constructs a Reader that reads from the default input stream.
|
Reader(structure5.List<Token> l)
Constructs a Reader that reads tokens from a List.
|
Reader(Token t)
Constructs a Reader that reads from a single Token.
