Cursorbased

Cursorbased is a descriptive term used in computing to denote approaches, interfaces, or data processing methods that revolve around a cursor—a pointer that marks a position within a data set, document, or user interface. It is not a single standardized specification, but a label applied in multiple contexts where a cursor guides traversal, selection, or retrieval.

In pagination, cursorbased pagination uses a cursor token that encodes the position of the last item retrieved. Clients present this token to fetch the next page. This method helps maintain consistency as data changes and scales well for large collections; it contrasts with offset-based pagination, which can become inconsistent and less efficient on large datasets. Common examples occur in social media APIs and content services.

In databases and data processing, a cursor is an object that iterates over a result set. Cursorbased processing fetches rows incrementally, enabling memory efficiency for large queries and streaming scenarios. Cursors can be forward-only or scrollable, and they require explicit opening, fetching, and closing.

In user interfaces, cursorbased interaction uses a pointer to navigate and select elements, such as menus or text editors. This can underpin accessibility strategies and keyboard navigation, with focus and selection driven by the cursor position rather than only commands.

Because cursorbased is an umbrella term rather than a formal specification, its exact meaning depends on context. It is often contrasted with page- or index-based approaches, providing a flexible mechanism for traversing, selecting, or streaming data.
