Detailed Description

template<typename V, typename Traits = DefaultPersistentValueVectorTraits>
class v8::PersistentValueVector< V, Traits >

A vector wrapper that safely stores Global values. C++11 embedders don't need this class, as they can use Global directly in std containers.

This class relies on a backing vector implementation, whose type and methods are described by the Traits class. The backing map will handle values of type PersistentContainerValue, with all conversion into and out of V8 handles being transparently handled by this class.
