Example 2 with CatalogPluginApi

use of org.killbill.billing.catalog.plugin.api.CatalogPluginApi in project killbill by killbill.

the class DefaultCatalogCache method getCatalogFromPlugins.

        // Beware plugin implementors:  latestCatalogUpdatedDate returned by the plugin should also match the effectiveDate of the VersionedCatalog.
        // 
        // However, this is the plugin choice to return one, or many catalog versions (StandaloneCatalog), Kill Bill catalog module does not care.
        // As a guideline, if plugin keeps seeing new Plans/Products, this can all fit into the same version; however if there is a true versioning
        // (e.g deleted Plans...), then multiple versions must be returned.
        //
