Class CompiledEquivalenceUtils

java.lang.Object

org.neo4j.cypher.internal.codegen.CompiledEquivalenceUtils

public final class CompiledEquivalenceUtils
extends Object

Helper class for dealing with equivalence an hash code in compiled code. Note this class contains a lot of duplicated code in order to minimize boxing.
