Example 1 with AionBlockchainImpl

use of org.aion.zero.impl.AionBlockchainImpl in project aion by aionnetwork.

the class RecoveryUtils method pruneAndCorrect.

/**
 * Used by the CLI call.
 */

        System.out.println("Empty database. Nothing to do.");
        return;
    }
    // revert to block number and flush changes
    store.pruneAndCorrect();
    store.flush();
    // compact database after the changes were applied
    blockchain.getRepository().compact();
    blockchain.getRepository().close();
}
