- def BeginToken(): Char
Returns the next character that marks the beginning of the next token.
Returns the next character that marks the beginning of the next token. All characters must remain in the buffer between two successive calls to this method to implement backup correctly.

- def Done(): Unit
The lexer calls this function to indicate that it is done with the stream and hence implementations can free any resources held by this class.
The lexer calls this function to indicate that it is done with the stream and hence implementations can free any resources held by this class. Again, the body of this function can be just empty and it will not affect the lexer's operation.

- def GetImage(): String
Returns a string made up of characters from the marked token beginning to the current buffer position.
Returns a string made up of characters from the marked token beginning to the current buffer position. Implementations have the choice of returning anything that they want to. For example, for efficiency, one might decide to just return null, which is a valid implementation.

- def GetSuffix(len: Int): Array[Char]
Returns an array of characters that make up the suffix of length 'len' for the currently matched token.
Returns an array of characters that make up the suffix of length 'len' for the currently matched token. This is used to build up the matched string for use in actions in the case of MORE. A simple and inefficient implementation of this is as follows :
{ String t = GetImage(); return t.substring(t.length() - len, t.length()).toCharArray(); }

- def backup(amount: Int): Unit
Backs up the input stream by amount steps.
Backs up the input stream by amount steps. Lexer calls this method if it had already read some characters, but could not use them to match a (longer) token. So, they will be used again as the prefix of the next token and it is the implementation's responsibility to do this right.
