Member Function Documentation

bool zypp::parser::yum::FileReaderBase::BaseImpl::consumePackageNode ( xml::Reader &  reader_r,
data::Packagebase_Ptr &  package_ptr 
)

Process package node and its subtree.

This method can be extended for specific implementations.

Parameters:
reader_r 
package_ptr This can be either data::Package or data::SrcPackage.
Returns:
true if the package node or current subnode has been consumed (no further processing is required), false otherwise.
Exceptions:
ParseException if a serious error is encountered while parsing

Todo:
what's 'archive' size of the package (it is neither the rpm file size nor its installed size)

bool zypp::parser::yum::FileReaderBase::BaseImpl::consumeFormatNode ( xml::Reader &  reader_r,
data::Packagebase_Ptr &  package_ptr 
)

Function for processing all format tag subtree nodes.

Returns:
true if the package node or current subnode has been consumed (no further processing is required), false otherwise.

Todo:
xpath: //format/rpm:sourcerpm where to store this?

Todo:
xpath: //format/rpm:header-range what is this?

Todo:
xpath: //format/suse:dirsizes (?)

Todo:
this is ambiguous - fix the rnc schema

bool zypp::parser::yum::FileReaderBase::BaseImpl::consumeDependency ( xml::Reader &  reader_r,
data::Dependencies &  deps_r 
)

Processes RPM dependency tags (rpm:entry, rpm:requires, .

..).

Returns:
true if a dependency tag has been encountered, false otherwise.
Exceptions:
ParseException if a serious error is encountered while parsing

Todo:
check <rpm:entry name="/bin/sh" pre="1">
