Package io.deephaven.jdbc

Class DeephavenArray

java.lang.Object

io.deephaven.jdbc.DeephavenArray

All Implemented Interfaces:

Array

public class DeephavenArray
extends Object
implements Array

A simple wrapper for when returning Deephaven array values from a ResultSet.

The API comtemplates arrays that are might be pulled from the server in pieces but since we have any given column row value in memory already, there is no provision for this here.

We don't support the ResultSet based slicing of arrays which seems to be designed for querying matrix-like table data (which could be efficiently sliced along multiple dimensions).
