Study Notes
Pipelines
- Pipelines are composed of individual units called Pipes.
- Pipes are responsible for completing a single task within a pipeline.
- Each pipe implements the IPipe interface.
- IPipe defines the parameter and result objects used by the pipe.
- Pipes execute in a defined order.
- Each pipe has an Order property in code.
- Pipes implement the IPipe interface with consistent parameter and result types.
- Pipes can be inserted into a pipeline in any order.
- To override an existing pipe, create a custom pipe with the same name and order.
Pipe Execution
- A pipe can stop the pipeline execution by setting the result object's error code or exit flag.
Example Pipeline: Product Pricing
- The CalculatePrice pipe retrieves product prices using a pricing service.
- The CalculatePrice pipe uses the IPricingServiceFactory to get the appropriate pricing service.
- The CalculatePrice pipe calculates the price for each pricing service parameter.
- The CalculatePrice pipe adds the calculated prices to the result object's ProductPriceDtos list.
Pipe Order Visualizer
- Configured Commerce provides a Visual Studio extension to visually show the order of pipes in a pipeline.
Using Pipelines in Code
- Inject a pipeline instance into the class constructor, like other objects.
