# getElements

## Return Value

## Discussion

Discussion Use this method to get the array of IOHIDElement objects that contain the data for the most recent device report. Each element contains data for a single aspect of the device’s state. For example, a report from a stylus contains separate elements for the horizontal and vertical position of the stylus, the pressure values, and so on. Use the getUsagePage and getUsage methods of the element to determine the type of information in each element. This method creates a new set of IOHIDElement objects the first time you call it. On subequent calls, it updates the existing IOHIDElement objects with data from the most recent report.
