| <pre> |
| root |
| |-- a: struct (nullable = false) |
| | |-- b: struct (nullable = false) |
| | | -- c: string (containsNull = false) |
| </pre> |
| Then we will use Position3Accessor to access nested field 'c'. It can be accessed like this: |
| <code>row.get(p0, StructLike.class).get(p1, StructLike.class).get(p2, javaClass)</code>. |
| Commonly, Nested fields with depth=1 or 2 or 3 are the fields that will be accessed frequently, |
| so this optimization will help to access this kind of schema. For schema whose depth is deeper than 3, |
| then we will use the <code>Accessors.WrappedPositionAccessor</code> to access recursively.</div> |
