Union of all known value types.

This is only used to specify the minimum payload memory for Eina_Value.

manages array type. Use the value get/set for arrays:

• eina_value_array_get() and eina_value_array_set()
• eina_value_array_vget() and eina_value_array_vset()
• eina_value_array_pget() and eina_value_array_pset()

eina_value_set() takes an Eina_Value_Array where just subtype and step are used. If there is an array, it will be copied (including each item) and its contents must be properly configurable as subtype expects. eina_value_pset() takes a pointer to an Eina_Value_Array. For your convenience, use eina_value_array_setup().

eina_value_get() and eina_value_pget() takes a pointer to Eina_Value_Array, it's an exact copy of the current structure in use by value, no copies are done.

manages blob of bytes type, see Eina_Value_Blob

eina_value_set() takes an Eina_Value_Blob eina_value_pset() takes a pointer to Eina_Value_Blob.

eina_value_get() and eina_value_pget() takes a pointer to Eina_Value_Blob and it's an exact copy of value, no allocations are made.

Memory is untouched unless you provide ops (operations) pointer.

manages hash type. Use the value get/set for hashes:

• eina_value_hash_get() and eina_value_hash_set()
• eina_value_hash_vget() and eina_value_hash_vset()
• eina_value_hash_pget() and eina_value_hash_pset()

eina_value_set() takes an Eina_Value_Hash where just subtype and buckets_power_size are used. If there is an hash, it will be copied (including each item) and its contents must be properly configurable as subtype expects. eina_value_pset() takes a pointer to an Eina_Value_Hash. For your convenience, use eina_value_hash_setup().

eina_value_get() and eina_value_pget() takes a pointer to Eina_Value_Hash, it's an exact copy of the current structure in use by value, no copies are done.

Note:

Be aware that hash data is always an allocated memory of size defined by subtype->value_size. If your subtype is an integer, add as data malloc(sizeof(int)). If your subtype is an string, add as data malloc(sizeof(char*)) and this data value must point to strdup(string)!

• eina_value_list_vget() and eina_value_list_vset()
• eina_value_list_pget() and eina_value_list_pset()

eina_value_set() takes an Eina_Value_List where just subtype is used. If there is an list, it will be copied (including each item) and its contents must be properly configurable as subtype expects. eina_value_pset() takes a pointer to an Eina_Value_List. For your convenience, use eina_value_list_setup().

• eina_value_struct_pget() and eina_value_struct_pset()

eina_value_set() takes an Eina_Value_Struct where just desc is used.

For your convenience, use eina_value_struct_setup().
