                          throws IOException

Parses a mime.types file, and generates mappings between MIME types and extensions. For example, if a line contains:

text/html   html htm

Then 'html' will be the default extension for text/html, and both 'html' and 'htm' will have MIME type 'text/html'. Lines starting with '#' are treated as comments and ignored. If an extension is listed for two MIME types, the first will be chosen.

Parameters:

in - Reader of bytes from mime.types file content

extMap - Empty map of default extensions, keyed by MIME type. Will be filled in by this method.

mimeMap - Empty map of MIME types, keyed by extension. Will be filled in by this method.

Throws:

IOException
