Description

This method tries to find a resource reader able to read the stream passed as parameter.

If an extension is specified, only readers matching that extension are tried. The extension is case-insensitive and includes the leading dot, unless the empty string is passed (which means "no extension", e.g. a unix executable, which doesn't have an extension).

If a suitable reader is found, an instance of that reader is returned.

Remark: To make a resource reader class known, add that resource reader unit to the uses clause of your program.

Errors

If no suitable reader is found, an EResourceReaderNotFoundException exception is raised.
