Create a range proctor to manage an array of objects at the specified origin. Optionally specify length to define its range, which by default is empty (i.e., length = 0). The sequence of objects may extend in either direction from origin. A positive length represents the sequence of objects starting at origin and extending "up" to length (not including the object at the index position origin + length). A negative length represents the sequence of objects starting at one position below origin and extending "down" to the absolute value of length (including the object at index position origin + length). If length is 0, then this range proctor manages no objects. The behavior is undefined unless both origin and length are zero, or origin is non‐zero and all objects (if any) within the managed range (as defined by length) are valid. Note that when length is non‐positive, the object at the origin is not managed by this range proctor. For example, if origin is at the index position 2, a length of 2 signifies that the objects at positions 2 and 3 are managed, whereas a length of ‐2 signifies that the objects at positions 0 and 1 are managed: ` length = ‐2 length = 2 |<‐‐‐‐‐>| |<‐‐‐‐‐>| ___ ___ ___ ___ ___ ___ ___ ___ ___ ___ | 0 | 1 | 2 | 3 | 4 | | 0 | 1 | 2 | 3 | 4 | `=ˆ=⁼⁼⁼=ˆ=' `=ˆ=<sup>===</sup>=ˆ=' ˆ‐‐‐‐‐‐‐‐‐‐‐‐ origin ˆ‐‐‐‐‐‐‐‐‐‐‐‐ origin `
