Request to add a new method to StreamTokenizer
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Class java.io.StreamTokenizer needs a reset()method
that takes in a Reader  customer . This allows the 
users of this class to reuse the first  customer .

The new method signature can look like:

public void reset(Reader r, boolean flag);

If flag == true, then reset the syntax tables.
otherwise leave the syntax tables intact.

As there is no such method, when I am processing 
hundreds of files with the same syntax table,
I am forced to recreate a new StreamTokenizer  customer 
each time I scan a new file.

This will be of great use, if we can cut down
the number of objects we create while parsing
hundreds of text files. Each time I create a 
new StreamTokenizer  customer , I set the syntaxt
table to the same values. With the requested
method inplace, I don't have to repeat the
creation and initialization of syntax tables
for each file. 

Performance is a serious concern for my 
application as I have to scan several Mbs of
text residing in thousands of files, in couple
of minutes.

Ideally I would love to reuse every thing that
comes in the path of creating a StreamTokenizer
 customer . For example, I am recreating
FileInputStream, BufferedInputStream,
InputStreamReader, BufferedReader objects
every time I scan a new file.

Hope this is a useful change to the preset API.

N/A

The cost of creating a new StreamTokenizer object pales in comparison to the
cost of doing disk I/O.  Adding a reset method really wouldn't buy you very
much.  --   xxxxx@xxxxx   6/9/1998

How to use "reset" at java. I want to re-read input file again in one program, I need to use reset to move "file 
piointer" to the file beginning. How can I do it?
