Class PDLInitializer

java.lang.Object
  com.arsdigita.runtime.PDLInitializer

All Implemented Interfaces:

Initializer

public class PDLInitializer

extends Object

implements Initializer

The PDLInitializer class provides an implementation of the Initializer interface that works in conjunction with the PDLSource interface and implementations thereof in order to provide a convenient way to initialize object-relational metadata. This class is most convenient when used in conjunction with the CompoundInitializer class. For example:

package com.arsdigita.exampleApp; public class Initializer extends CompoundInitializer { public Initializer() { final String url = RuntimeConfig.getConfig().getJDBCURL(); final int database = DbHelper.getDatabaseFromURL(url); add(new PDLInitializer (new ManifestSource ("example-app.pdl.mf", new NameFilter(DbHelper.getDatabaseSuffix(database), "pdl")))); } }

The class defined above will load all the object-relational metadata for the current database referenced from the example-app.pdl.mf manifest file.
