  +--jpos.config.simple.SimpleEntryRegistry

All Implemented Interfaces:

JposEntryRegistry

public class SimpleEntryRegistry

extends java.lang.Object

implements JposEntryRegistry

This is a simple implementation for the JposEntryRegistry using a Hashtable to collect the entries. The entry's logicalName property value is used as the key to the table and the entry itself as the value
