| <div class="block">An ORCv2 file writer. The file is divided into stripes, which is the natural |
| unit of work when reading. Each stripe is buffered in memory until the |
| memory reaches the stripe size and then it is written out broken down by |
| columns. Each column is written by a TreeWriter that is specific to that |
| type of column. TreeWriters may have children TreeWriters that handle the |
| sub-types. Each of the TreeWriters writes the column's data as a set of |
| streams. |
| |
| This class is unsynchronized like most Stream objects, so from the creation |
| of an OrcFile and all access to a single instance has to be from a single |
| thread. |
| |
| There are no known cases where these happen between different threads today. |
| |
| Caveat: the MemoryManager is created during WriterOptions create, that has |
| to be confined to a single thread as well.</div> |
