 This page will contain documentation for the end user. Will illustrate how to use fmgVen by code samples, step by step.

+
+== Quick Intro ==
+
+Here is a quick and dirty introduction to Ven. For more, see the [source:trunk/fmgVen/test/com/fmguler/ven/sample/Sample.java Sample.java] file in the test classes. (In the future, I am also planning to implement Pet Clinic sample application using Ven, which will be much more explanatory).
+
+The domain model used in the examples;
+
+!SomeDomainObject has both many to one and one to many relationship with !AnotherDomainObject (SDO.ado, SDO.ados). !AnotherDomainObject has many to one relationship with !SomeDomainObject (ADO.sdo).
+
+=== Save and Update ===
+
+{{{
+Ven ven = getVen();
+
+//insert
+SomeDomainObject obj = new SomeDomainObject();
+obj.setName("name");
+obj.setDescription("desc");
+obj.setDate(new Date());
+ven.save(obj);
+System.out.println(obj);
+
+//update
+obj.setName("name update");
+ven.save(obj);
+System.out.println(obj);
+}}}
+
+=== Delete ===
+
+{{{
+Ven ven = getVen();
+ven.delete(2, SomeDomainObject.class);
+}}}
+
+=== Get ===
+
+{{{
+Ven ven = getVen();
+
+//get with includes
+Set joins = new HashSet();
+joins.add("SomeDomainObject.anotherDomainObjects");
+joins.add("SomeDomainObject.anotherDomainObject");
+SomeDomainObject obj = (SomeDomainObject)ven.get(1, SomeDomainObject.class, joins);
+System.out.println(obj);
+
+Set joins2 = new HashSet();
+joins2.add("AnotherDomainObject.someDomainObject");
+AnotherDomainObject obj2 = (AnotherDomainObject)ven.get(1, AnotherDomainObject.class, joins2);
+System.out.println(obj2);
+}}}
+
+=== List ===
+
+{{{
+Ven ven = getVen();
+
+//list with includes
+Set joins = new HashSet();
+joins.add("SomeDomainObject.anotherDomainObjects");
+joins.add("SomeDomainObject.anotherDomainObject");
+List objList = ven.list(SomeDomainObject.class, joins);
+
+Iterator it = objList.iterator();
+while (it.hasNext()) {
+    SomeDomainObject someDomainObject = (SomeDomainObject)it.next();
+    System.out.println(someDomainObject);
+}
+}}}
+
+=== List by Criteria ===
+
+{{{
+Ven ven = getVen();
+
+//these objects will be included
+Set joins = new HashSet();
+joins.add("SomeDomainObject.anotherDomainObjects");
+joins.add("SomeDomainObject.anotherDomainObject");
+
+//the results will be filtered according to this criteria
+Criteria criteria = new Criteria() //criteria object
+        .like("SomeDomainObject.anotherDomainObjects.name", "a%") //attribute like value
+        .eq("SomeDomainObject.name", "sdo1") //attribute equals value
+        .and(); //connects previous criteria with logical and (postfix notation)
+
+//list with includes and criteria
+List objList = ven.list(SomeDomainObject.class, joins, criteria);
+
+//print the results
+Iterator it = objList.iterator();
+while (it.hasNext()) {
+    SomeDomainObject someDomainObject = (SomeDomainObject)it.next();
