Constructors
AbstractBinding
Creates the AbstractBinding.
Destructor
~AbstractBinding 
virtual ~AbstractBinding();
Destroys the AbstractBinding.
Member Functions
bind
virtual void bind(
std::size_t pos
) = 0;
Binds a value to the given column position
canBind
virtual bool canBind() const = 0;
Returns true if we have enough data to bind
getBinder 
AbstractBinder * getBinder() const;
Returns the AbstractBinder used for binding data.
numOfColumnsHandled
virtual std::size_t numOfColumnsHandled() const = 0;
Returns the number of columns that the binding handles.
The trivial case will be one single column but when complex types are used this value can be larger than one.
numOfRowsHandled
virtual std::size_t numOfRowsHandled() const = 0;
Returns the number of rows that the binding handles.
The trivial case will be one single row but for collection data types (ie vector) it can be larger.
reset
virtual void reset() = 0;
Allows a binding to be reused.
setBinder
void setBinder(
AbstractBinder * pBinder
);
Sets the object used for binding; object does NOT take ownership of the pointer.
