Example 51 with Address

use of org.aion.base.type.Address in project aion by aionnetwork.

the class AionRepositoryImplTest method testSyncToPreviousRootNoFlush.

/**
 * Tests behaviour for trie when trying to revert to a previous root without
 * first flushing. Note the behaviour here. Interestingly enough, it seems like
 * the trie must first be flushed, so that the root node is in the caching/db layer.
 *
 * Otherwise the retrieval methods will not be able to find the temporal root value.
