Function Documentation

uint64_t Hash_Table_count_by_walk

(

struct Hash_Table *

ht

)

counts the elements in the hashtable by walking through all the elements

Parameters

ht	where to count elements

Returns

the number of elements

Definition at line 425 of file Hash_Table.c.

Here is the call graph for this function:

void* Hash_Table_get	(	struct Hash_Table *	ht,
		uint64_t	key,
		void *	extra_arg,
		int(*)(void *, uint64_t, void *)	test_func
	)

retrieves an element from the hashtable

Parameters

ht	where to retrieve the element
key	the key of the wanted element
extra_arg	extra argument to pass to test_func
test_func	key comparison function. Takes a pointer to stored data, the key and an extra arg. returns 1 if test success

Returns

the found element

Here is the caller graph for this function:

void* Hash_Table_get_an_entry

(

struct Hash_Table *

ht

)

Retrieves the first found element of the hash table.

Parameters

ht	the hash table where to get the element

Returns

the element (NULL if the table is empty)

Warning

Only used in Unit Tests and Red_Ht_Table_get_an_entry() (which is never used...)

Definition at line 329 of file Hash_Table.c.

void* Hash_Table_push	(	struct Hash_Table *	ht,
		void *	payload,
		uint64_t	key
	)

adds an element to a hashtable

Parameters

ht	where to add the element
payload	the element to add
key	the key where to add it

Returns

the added element

void* Hash_Table_push_unique	(	struct Hash_Table *	ht,
		void *	payload,
		uint64_t	key,
		void *	extra_arg,
		int(*)(void *, uint64_t, void *)	test_func
	)

Adds an element into the hashtable. Replaces already existing element at key.

Parameters

ht	where to add the element
payload	the element to add
key	where to add it
extra_arg	extra argument to pass to test_func
test_func	the same test function used with Hash_Table_get()

Returns

the added element
