Method Detail

filterfile

public static java.io.InputStream filterfile(java.lang.String filename)
                                      throws java.io.IOException

check whether the InputStream contains compressed data. In this case execute gunzip and return a stream of decompressed data. If executing gunzip fails (e.g. not allowed for applets) or the input data were not compressed, the original InputStream is returned unchanged. Only works for standalone applications.

Throws:

java.io.IOException

filter

public static java.io.InputStream filter(java.io.InputStream in,
                                         java.lang.String tmp)
                                  throws java.io.IOException
