Detailed Description

template<typename T>
class ion::base::VectorDataContainer< T >

VectorDataContainer is a special kind of DataContainer that is backed by an AllocVector.

Accessing its underlying AllocVector provides a mechanism for a DataContainer with resizeable storage. Note that unlike a regular DataContainer, a VectorDataContainer can be created directly, but is templated on the type of the data.
