Example 6 with SyncInfo

use of org.aion.api.server.types.SyncInfo in project aion by aionnetwork.

the class ApiAion method getSyncInfo.

/**
 * Returns a {@link SyncInfo} object that reports whether or not syncing has started.

 * {@value SYNC_TOLERANCE} blocks of the network best block number.

 * @param localBestBlockNumber The current block number of the local node.
 * @param networkBestBlockNumber The current block number of the network.

Example 7 with SyncInfo

use of org.aion.api.server.types.SyncInfo in project aion by aionnetwork.

the class ApiWeb3Aion method eth_syncing.

 * {@value SYNC_TOLERANCE} blocks of the network best block number).

 * statistics relating to the sync: the block number the node was at when syncing began; the
 * current block number of the node; the current block number of the network.
 *
 * <p>If either the local block number or network block number cannot be determined, an {@link
 * RpcMsg} is returned with an {@link RpcError#INTERNAL_ERROR} code and its 'result' will be a
 * more descriptive string indicating what went wrong.
