Class ERXRetainer

java.lang.Object
  er.extensions.ERXRetainer

public class ERXRetainer

extends Object

Used as a generic way to retain a reference to an object so that it will not be collected by the garbage collector. This class is most often used to retain objects used to observe {link @NSNotification}s.

Note that the current implementation does not implement reference counting so calling retain multiple times on the same object does not have any effect after the first call.
