[jira] [Commented] (ORC-474) ColumnVectorBatch would benefit from a clear() method to reset all numElements recusively

> When dealing with deeply nested structure it can be quite tedious to reset all numElements recursively after a batch has been written. In practice, the simplest is probably for the client to create his own classes inheriting all of ColumnVectorBatches classes and adding such a clear() method to reset all numElements recursively.
> Shouldn't liborc just provide that?
