Three classes are used here;

ACE_Configuration_Heap

ACE_Configuration_Section_Key

ACE_Ini_ImpExp

First, initialize an ACE_Configuration_Heap to store the information obtained from reading the configuration file.

Ace_configuration_heap.open () I have read the source code of Ace. Based on my judgment, it is used to allocate space for heap. I have not fully understood how to do it.

Create an ace_ini_impexp object. The basic function of ace_ini_impexp is an adapter that initializes the section_map member of ace_configuration_heap through its import_config.

The ini configuration file divides configuration items into multiple sections.

Use the open_section () method of ace_configuration_heap to initialize an ace_configuration_section_key object to save a specific section.

Finally, the value of the configuration item is obtained through the get_string_value () get_integer_value () and get_binary_value () Methods of ace_configuration_heap. In my first understanding of string, integer is to use get_string if the configured value is string. If it is int, get_integer_value is used. Later I found that I was wrong. The three methods correspond to the three storage methods, which are stored by character, by integer, or by binary. The configuration items on one side are stored in string, so most of them use get_string_value.
