OCP
Introduction
OCPs: Object Aggregation Language
  • ‣ Java classes descibre single objects
  • ‣ OCPs describe multiple connected objects
Context of OCPs
  • ‣ OCPs are related to several technologies
OCP Usage
  • ‣ 1996: loading of test data
  • ‣ today: 15% OCPs compared to Java files
  • ‣ grown project (evolution...)
Getting Started
OCP Example: Test Data
<Product> <ArticleNumber>12345</Artikelnummer> <Name>Digital Receiver</Name> <ShortDescription>...</ShortDescription> <Description>...</Description> <Image><Name>pic1.jpg</Name></Image> <Preview><Name>pic2.jpg</Name></Preview> <Certificates/> <AdditionalImage>pic3a.jpg</AdditionalImage> <AdditionalImage>pic3b.jpg</AdditionalImage> <EnabledFrom NULL="true"/> <EnabledTil NULL="true"/> <Variant> <ArticleNumber>23456</ArticleNumber> <Feature><de>nein</de><en>no</en></Feature> </Variant> </ArticleNumber> </Product>
  • ‣ The example show a test objects to be loaded into a product database
OCP Example: Tests
<test CLASS="Aggregate::.../BuildAndTestFiling"> <TextLocator>oorl://Filing/...model03</TextLocator> <DoBuild>true</DoBuild> <DoTest>false</DoTest> </test>
A Simple Object Construction Plan
The following example shows a simple Object Construction Plan (OCP).
example.ocp
<Planet> <Name>world</Name> </Planet>
The respective Java Class
The Object Construction Plan loads an instance of class "Planet", which is defined as follows:
Planet.java
package org.xocp.test; public class Planet { protected String name; public String getName () { return this.name; } public void setName (String name) { this.name = name; } }
A Little Help
To run the example without any further preparation, we temporarily add an exact class specification.
example.ocp
<Planet CLASS="org.xocp.test.Planet"> <Name>world</Name> </Planet>
Some Test Code
Here's a test class which executes the OCP and prints out the result.
Test.java
package org.xocp.test; import org.xocp.factories.Factory_Aggregate; public class Test { public static void main(String[] args) { Planet p = (Planet) Factory_Aggregate.construct("example1.ocp"); System.out.println("Hello " + p.getName() + "!\n"); } }
Test Execution
To execute the test, the following command can be used. It is assumed, that the jar- and ocp-file are located in the current directory.
Testaufruf
java -classpath objectassembler.jar org.xocp.test.Test

OCP Example: Application-Aggregation
<Space Id="XYZ Gruppe"> <Equipments>...</Equipments> <Content>...</Content> <SubSpace Id="AdressStammdaten">... <SubSpace Id="Abrechnung">... <SubSpace Id="TourStammdaten...">... </Space>
OCP Example: User Interface Widgets
<object CLASS="Placeholder" KeepCreatedValue="true" PerSession="true"> <Equipments/> <Instantiator> <TargetClass>.../loginpanel</TargetClass> <Layout Resource.Style="ADOA-loginpanel"/> </Instantiator> </object>
OCP Example: Process Description
<Undertaking> <Work> <At> <Dates> ... <Date>1/5/2009</Date> <Date>1/6/2009</Date> <Date>1/7/2009</Date> ... </Dates> </At> <Aggregate>.../MonthlyWork</Aggregate> </Work> <Allocation> <Work OIDREF="work"/> <Responsibility/> <Agent Id="localhost"/> </Allocation> </Undertaking>
How it works
Factorysite, Scaffolds - No Database
Normally, each execution of an OCP yields a new instance of the corresponding object aggregate. OCPs describe a factory network and behave therefore like any factory, not like a database.
Test.java
... Planet p1 = (Planet) Factory_Aggregate.construct("file:example1.ocp"); Planet p2 = (Planet) Factory_Aggregate.construct("file:example1.ocp"); // two aggragates assert(p1 != p2); ...
Matching Factory Search
example3.ocp
<Planet xmlns="http://xmlns.xocp.org/test"> <Name>world</Name> </Planet>
Singleton
As with any good factory, you can modify this behaviour to get a singleton.
example.ocp
<Planet SINGLETON="true" CLASS="org.xocp.test.Planet"> <Name>world</Name> </Planet>
Test.java
... Planet p1 = (Planet) Factory_Aggregate.construct("file:example1.ocp"); Planet p2 = (Planet) Factory_Aggregate.construct("file:example1.ocp"); // singleton assert(p1 == p2); ...
Explicit Class, Factory, Retriever
<Planet xmlns="http://xmlns.xocp.org/test" CLASS="PlanetWithRing"> <Name>Saturn</Name> ... <RingDiameter>...</RingDiameter> </Planet>
<Planet xmlns="http://xmlns.xocp.org/test" FACTORY="Factory_PlanetWithRing"> <Name>Saturn</Name> ... <RingDiameter>...</RingDiameter> </Planet>
<Planet xmlns="http://xmlns.xocp.org/test" RETRIEVER="Retriever_PlanetWithRing"> <Query>rötlich, mit Ringen</Query> </Planet>
Factory & Retriever Interfaces

public class Retriever_PlanetWithRings { public void setQuery... public Planet retrieve () ... }

<Planet xmlns="http://xmlns.xocp.org/test"> <Diameter>12000</Diameter> <HasLifeForms>true</HasLifeForms> </Planet>
Enumerations
<Planet xmlns="http://xmlns.xocp.org/test"> <Farbe>ROT</Farbe> </Planet>
public enum Farben { ROT, GELB, GRUEN, BLAU }
Default Value
Planet.java
package org.xocp.test; public class Planet { ... public String defaultName () { return "world"; } }
<Planet xmlns="http://xmlns.xocp.org/test"/>
Embedded XML (Text)
<Planet xmlns="http://xmlns.xocp.org/test"> <Name>Saturn</Name> ... <Description CONTENT="XML/Text"> <section> <title>Saturn</title> <para> Saturn is a great planet. It has rings! </para> </section> </Description> </Planet>

Indented Text
<Planet xmlns="http://xmlns.xocp.org/test"> <Name>Saturn</Name> ... <Description CONTENT="Text/Indented"> Dieser Text ist hier hübsch eingerückt, in der Ausgabe jedoch *nicht*! </item27a> </Description> </Planet>
Configuration
Searchpath for Classes
In the OCP example, it was necessary to give the complete specification of the class name. Typically, that's tedious work.
Therefore, similar to the Java import directive you can specify a list of packages which are searches for classes.
The most simple way to this is to create the following property entry:
.properties
com.sphenon.basics.metadata.TypeManager.SearchPathes.DEFAULT\ =org.xocp.test:java.util:java.lang
To improve management of the OCP files and at the same time keep them concise, the search path can be associated to the XML namespace of the OCP.
Since namespaces may be associated with further information and since such a search path may be use in other contexts (e.g. project wide), the association is via another indirection, the socalled "type context" .
Alltogether the configuration looks like this:
.properties
org.xocp.TypeContext4XMLNS.http\://xmlns.xocp.org/test\ =org.xocp.testtc com.sphenon.basics.metadata.TypeManager.SearchPathes.\ org.xocp.testtc\ =org.xocp.test:java.util:java.lang
The first entry specifies the type context which is to be used within the given XML namespace.
The second entry contains the search path, which belongs to that type context.
The OCP now looks as follows. The example may not look that impressive (actually, it's longer than before), but in typically there's not just one class in it.
example.ocp
<Planet CLASS="Planet" xmlns="http://xmlns.xocp.org/test"> <Name>world</Name> </Planet>
Root Class
org.xocp.RootClass4XMLNS.http\://xmlns.xocp.org/test\ =org.xocp.test.Planet
example3.ocp
<Planet xmlns="http://xmlns.xocp.org/test"> <Name>world</Name> </Planet>
