public class HeapBytesVector extends AbstractHeapVector implements WritableBytesVector
When setting data by reference, the caller is responsible for allocating the byte arrays used to hold the data. You can also set data by value, as long as you call the initBuffer() method first. You can mix "by value" and "by reference" in the same column vector, though that use is probably not typical.
