Member Function Documentation

virtual bool Soprano::QueryResultIteratorBackend::next

(

)

[pure virtual]

For boolean results implementations needs to always return false to avoid endless loops in client applications that omit to check the result type.

QueryResultIterator::next

Implements Soprano::IteratorBackend< BindingSet >.

virtual BindingSet Soprano::QueryResultIteratorBackend::current

(

)

const [virtual]

The default implementation constructs the BindingSet using binding() and bindingNames()
