Member Function Documentation

int HSEPDataSqLite::SqLiteResultSet::forEach ( CycleBase & pCycleRef )

virtual

Batch operation using a CycleBase of derived class.

Parameters

pCycleRef

Returns: the quantity of times the CycleBase::execute function returned true.

Implements HSEPData::DBResultSet.

Definition at line 205 of file DBSqLite.cpp.

References HSEPData::CycleBase::execute(), HSEP::Array< T >::forEach(), HSEPDataSqLite::SQLResultData::isFirst(), HSEPDataSqLite::SQLResultData::isLast(), HSEPDataSqLite::SQLResultData::next(), and HSEPDataSqLite::SQLResultData::table().

Here is the call graph for this function:

int HSEPDataSqLite::SqLiteResultSet::forEach ( ExecuteFunctionType pFunction )

virtual

Batch operation using a stateless function.

When using a lambda function it is possible to "capture" surrounding variables, that would permit to the reentrant lambda function to perform state-related operations very similar to what a Cycle will do. However, when the complexity is high, it is recomended to use a particular Cycle type instead.

Parameters

pFunction
