Method Details

create

public static ConvexLocal create(Server server,
 Address address,
 AKeyPair keyPair)

isConnected

public boolean isConnected()

Description copied from class: Convex

Checks if this Convex client instance has an open connection.

Specified by:

isConnected in class Convex

Returns:

true if connected, false otherwise

acquire

public <T extends ACell> CompletableFuture<T> acquire(Hash hash,
 AStore store)

Description copied from class: Convex

Attempts to acquire a complete persistent data structure for the given hash from the connected peer. Uses the store provided as a destination.

Specified by:

acquire in class Convex

Parameters:

hash - Hash of value to acquire.

store - Store to acquire the persistent data to.

Returns:

Future for the Cell being acquired. May fail exceptionally or timeout if the given data cannot be acquired (most likely missing from the peer's store)

requestStatus

public CompletableFuture<Result> requestStatus()

Description copied from class: Convex

Submits a status request to the Convex network peer, returning a Future once the request has been successfully queued.

Specified by:

requestStatus in class Convex

Returns:

A Future for the result of the requestStatus

transact

public CompletableFuture<Result> transact(SignedData<ATransaction> signed)

Description copied from class: Convex

Submits a signed transaction to the Convex network, returning a Future once the transaction has been successfully queued.

Specified by:

transact in class Convex

Parameters:

signed - Signed transaction to execute

Returns:

A Future for the result of the transaction

requestChallenge

public CompletableFuture<Result> requestChallenge(SignedData<ACell> data)

Description copied from class: Convex

Request a challenge. This is request is made by any peer that needs to find out if another peer can be trusted.

Specified by:

requestChallenge in class Convex

Parameters:

data - Signed data to send to the peer for the challenge.

Returns:

A Future for the result of the requestChallenge

query

public CompletableFuture<Result> query(ACell query,
 Address address)

Description copied from class: Convex

Submits a query to the Convex network, returning a Future once the query has been successfully queued.

Specified by:

query in class Convex

Parameters:

query - Query to execute, as a Form or Op

address - Address to use for the query

Returns:

A Future for the result of the query

close

public void close()

Description copied from class: Convex

Disconnects the client from the network, releasing any connection resources.

Specified by:

close in class Convex

acquireState

public CompletableFuture<State> acquireState()
                                      throws TimeoutException

Description copied from class: Convex

Gets the consensus state from the remote Peer

Specified by:

acquireState in class Convex

Returns:

Future for consensus state

Throws:

TimeoutException - If initial status request times out
