Class UpgraderParams

java.lang.Object

      java.util.HashMap<java.lang.String,java.lang.Object>
          org.cafesip.upgrade.UpgraderParams

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map<java.lang.String,java.lang.Object>

public class UpgraderParams
extends java.util.HashMap<java.lang.String,java.lang.Object>

This singleton class is used to store information and objects that are shared between objects performing the upgrade function. The information is stored in key-value pairs and therefore the class extends java.util.HashMap. This information may be used by the script runner and other objects. For example, when a database connection is opened by the JdbcPatchEngine, it stores the JDBC connection as an entry in this object with the name - "org.cafesip.upgrade.connection. The SqlScriptRunner class retrieves the connection and uses it for its SQL operation. Similarly, an element with the name - org.cafesip.upgrade.properties contains the properties that are passed in the migration.properties file.
