Detailed Description
template<class T>
class odbcpp::buffer< T >
Class used to manage a block of memory.
This class is used internally to manage a block of memory necessary to dynamically bind to a database column of data.
This class derives from the object class that ensures the reference count is properly managed. Buffers are used in smart pointers and thus can safely be pointed as many times as necessary.

Constructor & Destructor Documentation
| odbcpp::buffer< T >::buffer | ( | size_t | size = 1 |
) | [inline] |
Allocate the block of data.
Initializes the buffer by allocating the necessary block of memory.
- Note:
- Also a buffer can have a size of 0, it is better to avoid such buffers since nothing can be done with them.
- Parameters:
-
[in] size The size used to allocate the new buffer.
| odbcpp::buffer< T >::~buffer | ( | ) | [inline] |
Free the block of data.
The destructor ensures that the block of memory allocated by the constructor is freed.

Member Function Documentation
| T* odbcpp::buffer< T >::get | ( | ) | const [inline] |
Retrieve the memory pointer.
This function returns the memory pointer that the constructor allocated. You can use it as required, but you cannot delete it.
This pointer cannot be null, however, it may pointer to an empty buffer (i.e. 0 size memory block.)
- Returns:
- The allocated memory pointer
