Interface CharStream

All Known Implementing Classes:
StringCharStream
public interface CharStream
This interface produces a sequence of chars. These can either be "read", which means basically the same as Reader.read(); or they can be "peeked", which means that the next character is returned, but not consumed, i.e. the next call to read() or peek() will return that character again.
