public static void streamCSV(java.io.InputStream stream,

                      throws java.io.IOException,

Given an InputStream that represents a CSV, stream each line into the CSVParser and call the callback for each line. This should encourage use of streams to prevent loading up large CSV's into String objects in memory. This method does not flush or close the stream. This is to avoid making non-portable assumptions about the stream's origin and further use. Thus the caller is still responsible for closing the InputStream after use.

Parameters:

stream - - The InputStream for reading a CSV file line by line

callback - - The Callback that is called after each line is read

Throws:

java.io.IOException - - If there was an IO problem while reading the InputStream

org.antlr.runtime.RecognitionException - - If there was a parsing issue related to the CSV
