public class SourceBackendSummarySetup : SourceExtension
The SourceBackendSummarySetup extension configures which ContactFields should be in the summary and which of those fields should be optimized for quicker search results.
Access the extension as follows:
extension = e_source_get_extension (source, E_SOURCE_EXTENSION_BACKEND_SUMMARY_SETUP);
The summary configuration is expected to be setup in only one way for a given Source at creation time. Any configurations made after creation of the book in question will be ignored.
