12.1.6 Command execution

Some common coding practices for when working with WebSphere Commerce commands are:

• Batch price retrieval calls.

  Looking up a price via one of the contract price retrieval task commands travels a lengthy code path. If your code has to look up several prices, it is faster to specify all of them in a single call rather than make a separate call for each price retrieval.

• Re-use command instances.

  Task and controller command instances are retrieved from the CommandFactory. They can be executed more than once in the same transaction. Call the reset method to re-initialize a command for re-execution.
