Class HashSearchResult

java.lang.Object

org.jruby.truffle.runtime.hash.HashSearchResult

public class HashSearchResult
extends Object

The result of looking for an entry (an Entry) in a Ruby hash. We get the previous entry in the lookup chain for this index until the entry was found, the entry that was found, and the index that was used. There are three possible outcomes for a search.

• There is nothing at that index, in which case the entry and previous entry in the chain will be null
• There were entries at that index, but none for our key, in which case the entry will be null, but the previous entry will be the last entry in the chain at that index, presumably where we will want to insert our new entry
• A entry was found for our key, in which case the entry will be the one correspond to the key, and the previous entry will be the one in the entry chain before that one
