In order to create a new Pipe, you have to create a new class that implements:
IPipe<ICategoryIndexingCommand<T>>, where T : NodeContentif you want to add a pipe for further processing of catalog categories.
IPipe<IEntryIndexingCommand<T>>, where T : EntryContentBaseif you want to add a pipe for further processing of catalog entries.
IPipe<IPageIndexingCommand<T>> where T : PageDataif you want to add a pipe for further processing of site pages.
You will have to implement 2 properties and a method
Order is a property which determines the priority of a pipe execution inside a pipeline.
Name is a property depicting the name of the pipe.
Execute is a method which holds the inner workings of the pipe. Generic parameter T is of type IPipeCommand. This is a base interface which the mentioned
ICategoryIndexingCommand,IEntryIndexingCommandandIPageIndexingCommandinherit from.
Afterwards, you have to register your pipe in order for it to be picked up and executed. Use one of the built-in extension methods:
ExtendCategoryIndexing<>()
ExtendProductIndexing<>()
ExtendVariantIndexing<>()
ExtendBundleIndexing<>()
ExtendPackageIndexing<>()
ExtendPageIndexing<>()
