Member Function Documentation

EndScan()

void taco::TableBulkLoadIterator::EndScan ( )

overridevirtual

Ends the scan.

If the subclass does want it to be called again in the destructor if it has been called, it should set m_key_schema to nullptr.

Implements taco::BulkLoadIterator.

Next()

bool taco::TableBulkLoadIterator::Next ( )

overridevirtual

Subclass should override the Next() function for moving to the next (key, record id) pair.

Upon a successful return, Next() should call IndexKey::Construct on the preallocated IndexKey m_key, which is sufficient to hold key_schema->GetNumFields() references to the keys, and m_recid is set record id this key maps to.

Implements taco::BulkLoadIterator.
