◆ cancelPut()

bool dht::DhtProxyClient::cancelPut	(	const InfoHash &	,
		const Value::Id &
	)

overridevirtual

Stop any put/announce operation at the given location, for the value with the given id.

Implements dht::DhtInterface.

◆ connectivityChanged()

void dht::DhtProxyClient::connectivityChanged ( sa_family_t )

inlineoverridevirtual

Inform the DHT of lower-layer connectivity changes. This will cause the DHT to assume a public IP address change. The DHT will recontact neighbor nodes, re-register for listen ops etc.

Implements dht::DhtInterface.

Definition at line 267 of file dht_proxy_client.h.

◆ exportNodes()

std::vector<NodeExport> dht::DhtProxyClient::exportNodes ( ) const

inlineoverridevirtual

Get the list of good nodes for local storage saving purposes The list is ordered to minimize the back-to-work delay.

Implements dht::DhtInterface.

Definition at line 255 of file dht_proxy_client.h.

◆ get()

virtual void dht::DhtProxyClient::get	(	const InfoHash &	key,
		GetCallback	cb,

		Value::Filter &&	f = `{}`,
		Where &&	w = `{}`
	)

overridevirtual

Get a value by asking the proxy and call the provided get callback when values are found at key. The operation will start as soon as the node is connected to the network.

Parameters

cb	a function called when new values are found on the network. It should return false to stop the operation.
donecb	a function called when the operation is complete. cb and donecb won't be called again afterward.
f	a filter function used to prefilter values.

Implements dht::DhtInterface.

◆ getLocal()

std::vector<Sp<Value> > dht::DhtProxyClient::getLocal	(	const InfoHash &	key,
		const Value::Filter &	f
	)		const

overridevirtual

Get locally stored data for the given hash.

Implements dht::DhtInterface.

◆ getLocalById()

Sp<Value> dht::DhtProxyClient::getLocalById	(	const InfoHash &	key,
		Value::Id	vid

◆ getNodesStats()

NodeStats dht::DhtProxyClient::getNodesStats ( sa_family_t af ) const

overridevirtual

Parameters

af	the socket family

Returns: node stats from the proxy

Implements dht::DhtInterface.

◆ getPublicAddress()

std::vector<SockAddr> dht::DhtProxyClient::getPublicAddress ( sa_family_t family = 0 )

overridevirtual

Parameters

family the socket family

Returns: public address

Implements dht::DhtInterface.

◆ getPut() [1/2]

std::vector<Sp<Value> > dht::DhtProxyClient::getPut ( const InfoHash & ) const

overridevirtual

Get data currently being put at the given hash.

Implements dht::DhtInterface.

◆ getPut() [2/2]

Sp<Value> dht::DhtProxyClient::getPut	(	const InfoHash &	,
		const Value::Id &
	)		const

overridevirtual

Get data currently being put at the given hash with the given id.

Implements dht::DhtInterface.

◆ getStatus()

NodeStatus dht::DhtProxyClient::getStatus ( sa_family_t af ) const

overridevirtual

Get the current status of the node for the given family.

Implements dht::DhtInterface.

◆ getStoreSize()

std::pair<size_t, size_t> dht::DhtProxyClient::getStoreSize ( ) const

inlineoverridevirtual

Returns the total memory usage of stored values and the number of stored values.

Implements dht::DhtInterface.

Definition at line 254 of file dht_proxy_client.h.

◆ insertNode()

void dht::DhtProxyClient::insertNode	(	const InfoHash &	,
		const SockAddr &
	)

inlineoverridevirtual

NOTE: The following methods will not be implemented because the DhtProxyClient doesn't have any storage nor synchronization process

Implements dht::DhtInterface.

Definition at line 252 of file dht_proxy_client.h.

◆ isRunning()

bool dht::DhtProxyClient::isRunning ( sa_family_t af = 0 ) const

overridevirtual

Returns true if the node is running (have access to an open socket).

af: address family. If non-zero, will return true if the node is running for the provided family.

Implements dht::DhtInterface.

◆ listen() [1/2]

virtual size_t dht::DhtProxyClient::listen	(	const InfoHash &	,
		ValueCallback	,
		Value::Filter	= `{}`,
		Where	= `{}`
	)

overridevirtual

Listen on the network for any changes involving a specified hash. The node will register to receive updates from relevent nodes when new values are added or removed.

Returns: a token to cancel the listener later.

Implements dht::DhtInterface.

◆ listen() [2/2]

virtual size_t dht::DhtProxyClient::listen	(	const InfoHash &	,
		GetCallback	,
		Value::Filter	= `{}`,
		Where	w = `{}`
	)

inlineoverridevirtual

Listen on the network for any changes involving a specified hash. The node will register to receive updates from relevent nodes when new values are added or removed.

Returns: a token to cancel the listener later.

Implements dht::DhtInterface.

overridevirtual

Announce a value on all available protocols (IPv4, IPv6).

The operation will start as soon as the node is connected to the network. The done callback will be called once, when the first announce succeeds, or fails. NOTE: For now, created parameter is ignored.

Implements dht::DhtInterface.

◆ query()

virtual void dht::DhtProxyClient::query	(	const InfoHash &	,
		QueryCallback	,
		DoneCallback	= `{}`,

Parameters

key	the key for which to query data for.
cb	a function called when new values are found on the network. It should return false to stop the operation.
done_cb	a function called when the operation is complete. cb and done_cb won't be called again afterward.
