Comparison Between Actions and Transformers

Comparison Between Actions and Transformers

Some actions perform operations that are similar to transformers, for example, modifying a string or querying a database. However, actions differ from transformers in some fundamental ways.
The following table summarizes the differences:
The input of a transformer is a single string.
The input is implemented by the action. An action can have multiple inputs. The inputs can be data holders.
The output of a transformer is a string.
The output is implemented by the action. For example, an action can create output data holders.
Side effects
A transformer has no side effects, other than modifying the input string.
An action can have side effects, such as updating a database.
