Bigdata2Sesame2BindingSetIterator

public Bigdata2Sesame2BindingSetIterator(ICloseableIterator<IBindingSet> src)

Parameters:

src - The source iterator (will be closed when this iterator is closed). All bound values in the visited IBindingSets MUST be either (a) BigdataValues -or- (b) IVs having a cached BigdataValue.
