How to Extend Pipes

In order to create a new Pipe, you have to create a new class that implements:

if you want to add a pipe for further processing of catalog categories.

if you want to add a pipe for further processing of catalog entries.

if 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, IEntryIndexingCommand and IPageIndexingCommand inherit 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<>()
