**javacard.framework** ====Interface Shareable ==== **All Known Subinterfaces:** [[javacard:java-card-api:SharedBioTemplate|SharedBioTemplate]] ---- The Shareable interface serves to identify all shared objects. Any object that needs to be shared through the applet firewall must directly or indirectly implement this interface. Only those methods specified in a shareable interface are available through the firewall. Implementation classes can implement any number of shareable interfaces and can extend other shareable implementation classes. ----
