All Implemented Interfaces:

PersistentObject

public class DataSource
extends java.lang.Object
implements PersistentObject

Constructor Detail

DataSource

public DataSource(java.lang.String name,
                  java.lang.String type,
                  int capability)

Creates a new instance of DataSource

Parameters:

name - of the data source schema that wraps around the actual data source

type - one of the following:

• TYP_SOURCE
• TYP_CACHE

capabilityCode - an integer representing the features of the AutoMedWrapper object used to create this data source schema

Method Detail

getName

public java.lang.String getName()

getKey

public PersistentKey getKey()

Specified by:

getKey in interface PersistentObject

getPersistentAttributes

public java.util.Map getPersistentAttributes()

Specified by:

getPersistentAttributes in interface PersistentObject

deserialise

public static DataSource deserialise(java.util.Map pa)
                              throws java.lang.IllegalArgumentException

This method guarantees that a PersistentObject can be deserialised properly from its own set of persistent attributes. It is a reverse of getPersistentAttributes()

Parameters:

pa - a HashMap of persistent attributes (created by {@link #getPersistentAttributes())

Throws:

java.lang.IllegalArgumentException
