setAttributesrange

setAttributesrange is a function used in editing and modeling APIs to assign a set of attributes to a contiguous span within a data structure that supports ranged attributes. The function is commonly found in rich-text editors, drawing tools, and data modeling libraries where elements or nodes carry attribute dictionaries.

Typical usage involves calling setAttributesrange with a target object or document model, a range defined by start and end positions, and an attributes object containing key–value pairs to apply. Optional parameters may control merging behavior, whether existing values should be overwritten, or whether the attributes should be validated against the target’s schema. Some implementations provide additional options such as transactional execution, which enables rollback if an error occurs during the update.

Behavior of the function generally includes applying the provided attributes to every element or node within the specified range. Conflict handling is governed by the supplied options: attributes may be overwritten, merged with existing ones, or left unchanged if conflicts are detected. In models that support transactions, setAttributesrange can be used to perform updates atomically, ensuring consistency across the range.

Return values vary by API. Common outcomes include a boolean success flag, a list of updated items, or an updated document/model instance suitable for method chaining. Some libraries expose a summary of changes to assist with rendering or undo/redo systems.

Usage examples include applying style attributes such as color, font weight, or visibility to a selected text range, or setting visual properties on a sequence of nodes in a graphic scene. See also: setAttribute, setAttributes, getAttributes, range, and transaction.
