Method Detail

getNextToken

public static Object getNextToken(StreamTokenizer tokenizer)
                           throws IOException

Returns the next token from a stream tokenizer. This special call tries to convert numbers of the format "2.13e-12" into real numbers. Without this method, the stream tokenizer will split them into two tokens: "2.13" and "e-12".

Parameters:

tokenizer - active StreamTokenizer from which to extract and parse the next token

Returns:

Throws:

IOException

displayErrorMessage

public static void displayErrorMessage(StreamTokenizer tokenizer,
                                       String strError)

Displays a tokenizer-related error message. This isn't intended for public consumption, although you could use it for displaying your own tokenizer-related error messages

Uses the provided tokenizer to display line numbers and token in an error message using the following format:

 Error reading data: line NNN: <strError>:<token>
 

Where strError is the String passed in as a parameter and token is the current token in the tokenizer.

Parameters:

tokenizer - active StreamTokenizer, preferably the one that has encountered some kind of error

strError - String to embed into the error message, as shown above
