From e878aedb8b53b311295a2df55ce5e865b1ad92b9 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Tue, 25 Aug 2009 15:32:40 +0200 Subject: "backport" the APT::Configuration class to apt-sid We can use it to simplify the internal code to operate with Acquire::CompressionTypes group. This also made it possible to set this setting with the -o flag. --- apt-pkg/aptconfiguration.h | 46 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 apt-pkg/aptconfiguration.h (limited to 'apt-pkg/aptconfiguration.h') diff --git a/apt-pkg/aptconfiguration.h b/apt-pkg/aptconfiguration.h new file mode 100644 index 000000000..6a123adce --- /dev/null +++ b/apt-pkg/aptconfiguration.h @@ -0,0 +1,46 @@ +// -*- mode: cpp; mode: fold -*- +// Description /*{{{*/ +/** \class APT::Configuration + * \brief Provide access methods to various configuration settings + * + * This class and their methods providing a layer around the usual access + * methods with _config to ensure that settings are correct and to be able + * to set defaults without the need to recheck it in every method again. + */ + /*}}}*/ +#ifndef APT_CONFIGURATION_H +#define APT_CONFIGURATION_H +// Include Files /*{{{*/ +#include +#include + /*}}}*/ +namespace APT { +class Configuration { /*{{{*/ +public: /*{{{*/ + /** \brief Returns a vector of usable Compression Types + * + * Files can be compressed in various ways to decrease the size of the + * download.
