Member Function Documentation

template<typename TInstance, typename TSize = std::size_t> virtual void uesqlc::IDataSource< TInstance, TSize >::closeCursor (  const mpcl::text::TString &    rkyCURSOR_NAME )  [pure virtual]

Closes the cursor. Parameters: rkyCURSOR_NAME  Cursor name.

template<typename TInstance, typename TSize = std::size_t> virtual size_type uesqlc::IDataSource< TInstance, TSize >::declareCursor (  const mpcl::text::TString &    rkyCURSOR_NAME )  [pure virtual]

Declares the cursor, and returns the tuple count of the query. Parameters: rkyCURSOR_NAME  Cursor name. Returns: Tuple count of the query.

template<typename TInstance, typename TSize = std::size_t> virtual void uesqlc::IDataSource< TInstance, TSize >::fetchAbsolute (  const mpcl::text::TString &    rkyCURSOR_NAME, TInstance &    rtINSTANCE, size_type    zINDEX )  [pure virtual]

Gets the data from tuple at position zINDEX in the cursor named rkyCURSOR_NAME and puts it into rtINSTANCE. Parameters: rkyCURSOR_NAME  Cursor name. rtINSTANCE  Data holder instance. zINDEX  Position of the tuple in the query.

template<typename TInstance, typename TSize = std::size_t> virtual void uesqlc::IDataSource< TInstance, TSize >::fetchNext (  const mpcl::text::TString &    rkyCURSOR_NAME, TInstance &    rtINSTANCE )  [pure virtual]

Gets the data from next tuple in the cursor named rkyCURSOR_NAME and puts it into rtINSTANCE. Parameters: rkyCURSOR_NAME  Cursor name. rtINSTANCE  Data holder instance.

template<typename TInstance, typename TSize = std::size_t> virtual void uesqlc::IDataSource< TInstance, TSize >::openCursor (  const mpcl::text::TString &    rkyCURSOR_NAME )  [pure virtual]

Opens the cursor. Parameters: rkyCURSOR_NAME  Cursor name.
