uint32_t num_peers
How many times a PeerID was put in this sampler.
struct GNUNET_TIME_Absolute birth
&#39;Birth&#39;
A sampler element sampling one PeerID at a time.
void RPS_sampler_elem_destroy(struct RPS_SamplerElement *sampler_elem)
Destroy a sampler element.
struct GNUNET_TIME_Absolute last_client_request
Time of last request.
void RPS_sampler_elem_set(struct RPS_SamplerElement *sampler_elem, struct GNUNET_CRYPTO_AuthKey auth_key)
Set the min-wise independent function of the given sampler element.
struct RPS_SamplerElement * RPS_sampler_elem_create(void)
Create a sampler element and initialise it.
void RPS_sampler_elem_reinit(struct RPS_SamplerElement *sampler_elem)
Reinitialise a previously initialised sampler element.
enum RPS_SamplerEmpty is_empty
Flag that indicates that we are not holding a valid PeerID right now.
struct GNUNET_PeerIdentity peer_id
The PeerID this sampler currently samples.
A 512-bit hashcode.
struct GNUNET_HashCode peer_id_hash
The according hash value of this PeerID.
The identity of the host (wraps the signing key of the peer).
RPS_SamplerEmpty
Used to indicate whether a sampler element is empty.
char * file_name
The file name this sampler element should log to.
struct GNUNET_CRYPTO_AuthKey auth_key
Min-wise linear permutation used by this sampler.
Time for absolute times used by GNUnet, in microseconds.
uint32_t num_change
How many times this sampler changed the peer_id.
type for (message) authentication keys
void RPS_sampler_elem_next(struct RPS_SamplerElement *sampler_elem, const struct GNUNET_PeerIdentity *new_ID)
Update a sampler element with a PeerID.
