static Eina_Bool eina_value_hash_del | ( | Eina_Value * | value, |
const char * | key | ||
) | [static] |
Removes element at given position in value of hash type.
- Parameters:
-
[in,out] value value object. [in] key key to find the member
- Returns:
- EINA_TRUE on success, EINA_FALSE otherwise.
- Since (EFL) :
- 1.2
static Eina_Bool eina_value_hash_get | ( | const Eina_Value * | value, |
const char * | key, | ||
... | |||
) | [static] |
Gets the generic value from an hash member.
- Parameters:
-
[in] value Source value object [in] key Key to find the member [out] ...
- Returns:
- EINA_TRUE on success, EINA_FALSE otherwise.
The value is returned in the variable argument parameter, the actual value is type-dependent, but usually it will be what is stored inside the object. There shouldn't be any memory allocation, thus the contents should not be freed.
The variable argument is dependent on chosen subtype. The list for basic types:
- EINA_VALUE_TYPE_VALUE: Eina_Value*
- EINA_VALUE_TYPE_ERROR: Eina_Error*
- EINA_VALUE_TYPE_UCHAR: unsigned char*

Eina_Value* eina_value_hash_new | ( | const Eina_Value_Type * | subtype, |
unsigned int | buckets_power_size | ||
) |
Creates generic value storage of type hash.
- Parameters:
-
[in] subtype How to manage this hash members. [in] buckets_power_size How to allocate hash buckets (2 ^ buckets_power_size), if zero then a sane value is chosen.
- Returns:
- The new value, or
NULL
on failure.
Creates a new generic value storage of type hash. The members are managed using the description specified by subtype.
On failure, NULL
is returned.
- Note:
- this creates from mempool and then uses eina_value_hash_setup().
