class AnyRef

[Source: none]

`` `class` AnyRef
  `extends` Any

  Class `AnyRef` is the root class of all reference types.

Method Summary
`final def` | != (arg0 : AnyRef) : Boolean
`final def` | == (arg0 : AnyRef) : Boolean
`protected def` | clone : AnyRef
`final def` | eq (arg0 : AnyRef) : Boolean
`def` | equals (arg0 : Any) : Boolean
`protected def` | finalize : Unit
`final def` | getClass : Class
`def` | hashCode : Int
`final def` | ne (arg0 : AnyRef) : Boolean
`final def` | notify : Unit
`final def` | notifyAll : Unit
`final def` | synchronized [T0](arg0 : T0) : T0 To make your programs thread-safe, you must first identify what data will be shared across threads. If you are writing data that may be read later by another thread, or reading data that may have been written by another thread, then that data is shared, and you must synchronize when accessing it.
`def` | toString : String
`final def` | wait (arg0 : Long, arg1 : Int) : Unit
`final def` | wait (arg0 : Long) : Unit
`final def` | wait : Unit

  To make your programs thread-safe, you must first identify what data will be shared across threads. If you are writing data that may be read later by another thread, or reading data that may have been written by another thread, then that data is shared, and you must synchronize when accessing it.
