SYNOPSIS use AptPkg;
DESCRIPTION The AptPkg module provides a low-level XS interface to libapt-pkg. Note that this interface is intended to be internal, and may change, see the AptPkg::Config, AptPkg::System, AptPkg::Version, AptPkg::Cache, Apt::Policy and AptPkg::Source classes for a higher level interface. AptPkg The AptPkg package provides the following functions: _init_config(CONF) Initialise a Configuration object (pkgInitConfig). See the init method in AptPkg::Config. _init_system(CONF) Return a pointer to the system object (pkgInitSystem). See the system method in AptPkg::Config. _parse_cmdline(CONF, ARG_DEFS, ...) Constructs a CommandLine instance, invokes the Parse method and returns the remaining arguments. See the parse_cmdline method in AptPkg::Config. AptPkg::_config The AptPkg::_config package wraps a Perl class around the Configuration class. It provides an instance of the global _config object, and exposes the following methods: Find, FindFile, FindDir, FindB, FindAny, Set, Exists, ExistsAny, Tree and Dump. The functions ReadConfigFile and ReadConfigDir are also provided within the package and may be used as methods. AptPkg::_config::item The AptPkg::_config::item package wraps a Perl class around the Configuration::Item class. The AptPkg::_config Tree method returns an instance of this class. Methods: Value, Tag, FullTag, Parent, Child and Next. AptPkg::System The AptPkg::System package wraps a Perl class around the pkgSystem class. It provides an instance of the global _system object, and exposes the following methods: Label, VS, Lock and UnLock. AptPkg::Version The AptPkg::Version package wraps a Perl class around the pkgVersioningSystem class. It exposes the following methods: Label, CmpVersion, CmpReleaseVer, CheckDep and UpstreamVersion. AptPkg::_cache The AptPkg::_cache package wraps a Perl class around the pkgCacheFile class. It exposes the following methods: Open, Close, FindPkg, PkgBegin, FileList, Packages, Policy, MultiArchCache and NativeArch. AptPkg::Cache::_package The AptPkg::Cache::_package package wraps a Perl class around the pkgCache::PkgIterator class. It exposes the following methods: Next, Name, FullName, Arch, Section, VersionList, CurrentVer, RevDependsList, ProvidesList, Index, SelectedState, InstState, CurrentState and Flags. AptPkg::Cache::_version The AptPkg::Cache::_version package wraps a Perl class around the pkgCache::VerIterator class. It exposes the following methods: VerStr, Section, MultiArch, Arch, ParentPkg, DescriptionList, TranslatedDescription, DependsList, ProvidesList, FileList, Index and Priority. AptPkg::Cache::_depends The AptPkg::Cache::_depends package wraps a Perl class around the pkgCache::DepIterator class. It exposes the following methods: TargetVer, TargetPkg, ParentVer, ParentPkg, Index, CompType and DepType. AptPkg::Cache::_provides The AptPkg::Cache::_provides package wraps a Perl class around the pkgCache::PrvIterator class. It exposes the following methods: Name, ProvideVersion, OwnerVer, OwnerPkg and Index. AptPkg::Cache::_description The AptPkg::Cache::_description package wraps a Perl class around the pkgCache::DescIterator class. It exposes the following methods: LanguageCode, md5 and FileList. AptPkg::Cache::_pkg_file The AptPkg::Cache::_pkg_file package wraps a Perl class around the pkgCache::PkgFileIterator class. It exposes the following methods: FileName, Archive, Component, Version, Origin, Label, Site, IndexType and Index. AptPkg::Cache::_ver_file The AptPkg::Cache::_ver_file package wraps a Perl class around the pkgCache::VerFileIterator class. It exposes the following methods: File, Index, Offset and Size. AptPkg::Cache::_desc_file The AptPkg::Cache::_desc_file package wraps a Perl class around the pkgCache::DescFileIterator class. It exposes the following methods: File AptPkg::Cache::_pkg_records The AptPkg::Cache::_pkg_records package wraps a Perl class around the pkgRecords class. It exposes the following methods: Lookup. AptPkg::_policy The AptPkg::_policy package wraps a Perl class around the pkgPolicy class. It exposes the following methods: GetPriority, GetMatch and GetCandidateVer. AptPkg::_source_list The AptPkg::_source_list package wraps a Perl class around the pkgSourceList class. Required as an argument to the AptPkg::_src_records constructor. AptPkg::_src_records The AptPkg::_src_records package wraps a Perl class around the pkgSrcRecords class. It exposes the following methods: Restart, Find. Constants The following APT enumerations are included, used by attributes of AptPkg::Cache. pkgCache::Version::VerMultiArch "AptPkg::Version::None", "AptPkg::Version::All", "AptPkg::Version::Foreign", "AptPkg::Version::Same", "AptPkg::Version::Allowed", "AptPkg::Version::AllForeign" and "AptPkg::Version::AllAllowed". pkgCache::Dep::DepType "AptPkg::Dep::Depends", "AptPkg::Dep::PreDepends", "AptPkg::Dep::Suggests", "AptPkg::Dep::Recommends", "AptPkg::Dep::Conflicts", "AptPkg::Dep::Replaces" and "AptPkg::Dep::Obsoletes". pkgCache::Dep::DepCompareOp "AptPkg::Dep::Or", "AptPkg::Dep::NoOp", "AptPkg::Dep::LessEq", "AptPkg::Dep::GreaterEq", "AptPkg::Dep::Less", "AptPkg::Dep::Greater", "AptPkg::Dep::Equals" and "AptPkg::Dep::NotEquals". pkgCache::State::VerPriority "AptPkg::State::Important", "AptPkg::State::Required", "AptPkg::State::Standard", "AptPkg::State::Optional" and "AptPkg::State::Extra". pkgCache::State::PkgSelectedState "AptPkg::State::Unknown", "AptPkg::State::Install", "AptPkg::State::Hold", "AptPkg::State::DeInstall" and "AptPkg::State::Purge". pkgCache::State::PkgInstState "AptPkg::State::Ok", "AptPkg::State::ReInstReq", "AptPkg::State::HoldInst" and "AptPkg::State::HoldReInstReq". pkgCache::State::PkgCurrentState "AptPkg::State::NotInstalled", "AptPkg::State::UnPacked", "AptPkg::State::HalfConfigured", "AptPkg::State::HalfInstalled", "AptPkg::State::ConfigFiles" and "AptPkg::State::Installed". pkgCache::Flag::PkgFlags "AptPkg::Flag::Auto", "AptPkg::Flag::Essential" and "AptPkg::Flag::Important".
