Detailed Description

Ed_result_set – a container with result set rows.

Constructor & Destructor Documentation

◆ Ed_result_set() [1/2]

Ed_result_set::Ed_result_set ( List< Ed_row > *  rows_arg,
Ed_row fields,
size_t  column_count_arg,
MEM_ROOT mem_root_arg 
)

Initialize an instance of Ed_result_set.

Instances of the class, as well as all result set rows, are always allocated in the memory root passed over as the third argument. In the constructor, we take over ownership of the memory root. It will be freed when the class is destroyed.

sic: Ed_result_est is not designed to be allocated on stack.

◆ ~Ed_result_set()

Ed_result_set::~Ed_result_set ( )

We don't call member destructors, they all are POD types.
