Detailed Description

template<class BtreeLayout>
struct mongo::BtreeLogic< BtreeLayout >::FullKey

This is an in memory wrapper for the variable length data associated with a KeyHeaderType.

It points to on-disk data but is not itself on-disk data.

This object and its BSONObj 'key' will become invalid if the KeyHeaderType data that owns this it is moved within the btree. In general, a KeyWrapper should not be expected to be valid after a write.
