Class UniqueTag

java.lang.Object
  org.mozilla.javascript.UniqueTag

All Implemented Interfaces:

java.io.Serializable

public final class UniqueTag
extends java.lang.Object
implements java.io.Serializable

Class instances represent serializable tags to mark special Object values.

Compatibility note: under jdk 1.1 use org.mozilla.javascript.serialize.ScriptableInputStream to read serialized instances of UniqueTag as under this JDK version the default ObjectInputStream would not restore them correctly as it lacks support for readResolve method
