U:RDoc::NormalClass[iI"Exception:ET@I" Object;To:RDoc::Markup::Document: @parts[o;;[o: RDoc::Markup::Paragraph;[ I"DDescendants of class Exception are used to communicate between ;TI"PKernel#raise and +rescue+ statements in <code>begin ... end</code> blocks. ;TI"NException objects carry information about the exception -- its type (the ;TI"Kexception's class name), an optional descriptive string, and optional ;TI"Etraceback information.
