Detailed Description

Interface for writing elements into an array datum.

This class wraps a BlockWriter which is a cursor onto elements of an array datum. Use the wrapped BlockWriter to write element data, and then finalize the array contents by calling ArrayWriter::commit. This does any necessary post-processing to convert the element data into a canonical array datum.
