Package org.jruby

Class RubyHash

java.lang.Object

org.jruby.RubyBasicObject

org.jruby.RubyObject

org.jruby.RubyHash

All Implemented Interfaces:

Serializable, Cloneable, Comparable<IRubyObject>, Map, InstanceVariables, InternalVariables, IRubyObject, CoreObjectType

Direct Known Subclasses:

MapJavaProxy.RubyHashMap, RubyGlobal.StringOnlyRubyHash, RubySet.DivideTSortHash

public class RubyHash
extends RubyObject
implements Map

Implementation of the Hash class. Concurrency: no synchronization is required among readers, but all users must synchronize externally with writers.
