Class NameServiceImple

java.lang.Object
  com.arjuna.ats.arjuna.gandiva.nameservice.NameServiceImple

All Implemented Interfaces:

java.lang.Cloneable

public abstract class NameServiceImple

extends java.lang.Object

implements java.lang.Cloneable

NameService implementations are typically used by ObjectName to store and retrieve object data in a manner specific to the NameService. So, for example, one such implementation may use a database, whereas another may use a remote property service. These details are hidden by the implementation. All NameService implementations must derive from this base class and provide implementations of the abstract methods.

Since:

JTS 1.0.
