Example 4 with ByteArrayKeyValueDatabase

use of org.aion.db.impl.ByteArrayKeyValueDatabase in project aion by aionnetwork.

the class AionRepositoryImpl method getReferencedTrieNodes.

/**
 * Retrieves nodes referenced by a trie node value, where the size of the result is bounded by
 * the given limit.
 *
 * @param value a trie node value which may be referencing other nodes
 * @param limit the maximum number of key-value pairs to be retrieved by this method, which
 *     limits the search in the trie; zero and negative values for the limit will result in no
 *     search and an empty map will be returned
 * @param dbType the database where the value was stored and further keys should be searched for
 * @return an empty map when the value does not reference other trie nodes or the given limit is
 *     invalid, or a map containing all the referenced nodes reached while keeping within the
 *     limit on the result size
