Detailed Description

Instructs Eet about memory management for different needs under serialization and parse process.

The list and hash methods match the Eina API, so for a more detailed reference on them, look at the Eina_List and Eina_Hash documentation, respectively. For the most part these will be used with the standard Eina functions, so using EET_EINA_STREAM_DATA_DESCRIPTOR_CLASS_SET() and EET_EINA_FILE_DATA_DESCRIPTOR_CLASS_SET() will set up everything accordingly.

Examples:

eet-data-file_descriptor_01.c, eet-data-file_descriptor_02.c, eet-data-nested.c, and eet-data-simple.c.

Field Documentation

int _Eet_Data_Descriptor_Class::version

ABI version.

Should always be set to EET_DATA_DESCRIPTOR_CLASS_VERSION

Examples:

eet-data-file_descriptor_02.c.

Referenced by eet_data_descriptor_new(), eet_eina_file_data_descriptor_class_set(), and eet_eina_stream_data_descriptor_class_set().

Eet_Descriptor_List_Next_Callback _Eet_Data_Descriptor_Class::list_next

how to iterate to the next element of a list.

Receives and should return the list node.

Referenced by eet_data_descriptor_new(), and eet_eina_stream_data_descriptor_class_set().

Eet_Descriptor_Type_Get_Callback _Eet_Data_Descriptor_Class::type_get

get the type, as used in the union or variant mapping, that should be used to store the given data into the eet file.

Examples:

eet-data-file_descriptor_02.c.
