# The SummaryInfoVisitorBase Class

Defined in: `Keyview_SummaryInformation.hpp`

The `SummaryInfoVisitorBase` class is an abstract base class that operates with the `SummaryInfoItem::`apply_visitor function. You use the `SummaryInfoVisitorBase` class by defining a class that inherits from it, implementing the required pure virtual member functions to handle each of the possible summary information types. You then call apply_visitor with an instance of your new class. The apply_visitor function ensures that the correct member function of your visitor is called with the summary information item in its original type.

DEPRECATED: The `SummaryInfoVisitorBase` class is deprecated in KeyView 23.2.0 and later.

OpenText recommends that you access metadata for a file by calling Session::get_metadata. OpenText recommends that you access subfile metadata that is stored in a container by calling Subfile::metadata. After calling these functions you can use the functions in the Metadatum class to process metadata elements.

This class and its functions are still available for existing implementations, but might be incompatible with new functionality and might be removed in future.
