Study Notes
Handlers
- Handlers are objects responsible for processing business logic in Configured Commerce.
- Handlers execute after the REST API receives and processes a request.
- Handlers are organized into chains that operate on specific objects.
- Each handler in a chain is executed in a configured order until there are no more handlers.
- The
GetCartHandlerchain retrieves and returns the cart object for the authenticated user or using a cart identifier. - The
GetCartHandlerchain includes handlers for retrieving cart-related data such as cart lines, shipping costs, taxes, and available carriers. - The
GetCartHandlerchain is used indirectly throughout the storefront, including when a user visits the Cart page, navigates to the Checkout Address page, and proceeds to the Review and Pay page. - The
GetProductHandlerchain retrieves a product given a product identifier. - The
GetProductHandlerchain is executed when a user visits the Product Detail page or searches for a product on the Quick Order page. - New handlers can be added to existing handler chains to insert new business logic.
Pipelines
- Pipelines are reusable portions of business logic that are not transactional.
- Pipelines are made up of one or more classes, called pipes.
- Pipelines are similar to handler chains.
- Pipelines can be executed wherever the logic is needed.
- Individual pipes within a pipeline can halt execution of the rest of the pipeline by returning an error code or exiting the pipeline.
- To be used within a pipeline, a pipe must:
- Implement the
IPipeinterface. - Return a result from the
Executemethod. - Specify an order via the
Orderproperty.
- Implement the
- The
Executemethod is the sole entry point into a pipe and contains the business logic used by the pipe. - The
Orderproperty is used to specify the order of the pipe within the pipeline. - Pipes within a pipeline are executed in ascending order based on the
Orderproperty. - Pipelines have at least one pipe with an order value of 100.
- Additional pipes typically increment the order by 100.
- A new pipe can be added to a pipeline by specifying an order value within a specific range.
- To insert a new pipe in between existing pipes, the order value should be between the order values of the existing pipes.
- To add a new pipe to the start or end of a pipeline, the pipe should be given an order value less than 100 or greater than the highest order value in the pipeline, respectively.
- It is possible to replace an existing pipe in a pipeline.
- To replace an existing pipe, the new pipe must:
- Implement the
IPipeinterface. - Return a result from the
Executemethod. - Specify an order via the
Orderproperty. - Be named the same as the pipe being replaced.
- The
Ordervalue for the new pipe should match theOrdervalue of the pipe being replaced.
- Implement the
- You cannot "remove" a pipe, but you can create an implementation of it that does nothing.
