PackageProvider::Impl * zypp::repo::PackageProvider::Impl::factoryMake ( RepoMediaAccess &  access_r, const Package::constPtr &  package_r, const DeltaCandidates &  deltas_r, const PackageProviderPolicy &  policy_r  )

static

Factory method providing the appropriate implementation.

Called by PackageProvider ctor. Returned pointer should be immediately wrapped into a smartpointer.

Definition at line 443 of file PackageProvider.cc.

ManagedFile zypp::repo::PackageProvider::Impl::providePackage

(

)

const

Provide the package.

The basic workflow.

Exceptions

Exception.

Definition at line 194 of file PackageProvider.cc.

ManagedFile zypp::repo::PackageProvider::Impl::providePackageFromCache ( ) const

protectedpure virtual

Lookup the final rpm in cache.

Default implementation (cache miss).

A non empty ManagedFile will be returned to the caller. File disposal depending on the repos keepPackages setting are handled in providePackage.

Note

The provoided default implementation returns an empty ManagedFile (cache miss).

Implemented in zypp::repo::PluginPackageProvider, and zypp::repo::RpmPackageProvider.

Definition at line 177 of file PackageProvider.cc.

ManagedFile zypp::repo::PackageProvider::Impl::doProvidePackage ( ) const

protectedpure virtual

Actually provide the final rpm.

Default implementation (provide full package)

Report start/problem/finish and retry loop are hadled by providePackage. Here you trigger just progress and delta/plugin callbacks as needed.

Proxy methods for progressPackageDownload and failOnChecksum are provided here. Create similar proxies for other progress callbacks in derived classes and link it to ProvideFilePolicy for download:

ProvideFilePolicy policy;
policy.progressCB( bind( &Base::progressPackageDownload, this, _1 ) );
policy.failOnChecksumErrorCB( bind( &Base::failOnChecksumError, this ) );
return _access.provideFile( _package->repoInfo(), loc, policy );

Note

The provoided default implementation retrieves the packages default location.

Implemented in zypp::repo::PluginPackageProvider, and zypp::repo::RpmPackageProvider.
