What is the primary function of a Row Iterator in a List View?

The primary function of a Row Iterator in a List View is to process the related array and produce a row for each entity instance. This means that when displaying data in a List View, the Row Iterator traverses through an array of objects (or entities) and generates a corresponding row in the user interface for each entity, allowing for individual representation and interaction with each line of data.

This functionality is essential for dynamically creating user interfaces that can display varying amounts of data based on underlying data sources, such as databases or collections. By having a Row Iterator handle this process, it ensures that the List View remains flexible and efficient in presenting data, as it can automatically adapt to changes in the number of entity instances.

The other options, while related to data handling, do not accurately describe the specific role of a Row Iterator in this context. For instance, summarizing all data at once pertains to aggregation functions, while creating a data form for each cell involves a different aspect of data manipulation in user interfaces. Filtering data based on user input is typically managed through other components or mechanisms designed specifically for that purpose rather than the Row Iterator itself.
