The demand is used to specify a dependency on a supply

is it update as below?

e.g.:
ISupply must be installed before IDemand is constructed
<bean name="IDemand" ...
<,demand whenRequired="Instantiated">>theSupply<,/demand>
</bean>
<bean name="ISupply" ...>
<,supply>theSupply<,/supply>
</bean>
]]

I try to work two samples,resoult as same.


sample1:
<deployment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="urn:jboss:bean-deployer bean-deployer_2_0.xsd"
 xmlns="urn:jboss:bean-deployer:2.0">
 <bean name="Integer" class="org.jboss.example.microcontainer.constructor.ConstructorBean" whenRequired="Instantiated">
 <constructor>
 <parameter class="int">4</parameter>
 </constructor>
 <demand >HAPPY</demand>
 </bean>
 <bean name="StringLong" class="org.jboss.example.microcontainer.constructor.ConstructorBean" >
 <constructor>
 <parameter>a string</parameter>
 <parameter class="long">10</parameter>
 </constructor>
 <supply>HAPPY</supply>
 </bean>
</deployment>

sample2:
<deployment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="urn:jboss:bean-deployer bean-deployer_2_0.xsd"
 xmlns="urn:jboss:bean-deployer:2.0">
 <bean name="Integer" class="org.jboss.example.microcontainer.constructor.ConstructorBean" >
 <constructor>
 <parameter class="int">4</parameter>
 </constructor>
 <demand whenRequired="Instantiated" >HAPPY</demand>
 </bean>
 <bean name="StringLong" class="org.jboss.example.microcontainer.constructor.ConstructorBean" >
 <constructor>
 <parameter>a string</parameter>
 <parameter class="long">10</parameter>
 </constructor>
 <supply>HAPPY</supply>
 </bean>
</deployment>

Visit node AbstractDemandMetaData@5e176f{demand=HAPPY whenRequiredDescribed}
Dependencies for Integer: [AbstractDemandMetaData$DemandDependencyItem@c9131c{name=Integer dependsOn=null whenRequired=Described resolved=false demand=HAPPY}]
Still unresolved Described:....
Installing name=StringLong..
.....
StringLong Installed
Dependencies resolved Integer for Described
.....
Integer Installed
.....

Is Visit node AbstractDemandMetaData@5e176f{demand=HAPPY whenRequiredDescribed} correct ?
Or is Visit node AbstractDemandMetaData@5e176f{demand=HAPPY whenRequiredInstantiated}.

 e.g.:
 ISupply must be installed before IDemand is constructed
 <bean name="IDemand" ...
 <demand whenRequired="Instantiated">theSupply</demand>
 </bean>

The xsd is wrong.

 public void attributes(Object o, QName elementName, ElementBinding element, Attributes attrs, NamespaceContext nsCtx)
 {
 AbstractDemandMetaData demand = (AbstractDemandMetaData) o;
 for (int i = 0; i < attrs.getLength(); ++i)
 {
 String localName = attrs.getLocalName(i);
 if ("state".equals(localName))
 demand.setWhenRequired(new ControllerState(attrs.getValue(i)));
 }
 }

So it should be:

 e.g.:
 ISupply must be installed before IDemand is constructed
 <bean name="IDemand" ...
 <demand state="Instantiated">theSupply</demand>
 </bean>

Thank you for telling me :-)
So do this:

 TypeBinding beanType = schemaBinding.getType(beanTypeQName);

 /*
 ClassMetaData classMetaData = new ClassMetaData();
 classMetaData.setImpl(AbstractBeanMetaData.class.getName());
 beanType.setClassMetaData(classMetaData);

 QName CLASS = new QName("class");
 AttributeBinding attribute = beanType.getAttribute(CLASS);
 PropertyMetaData propertyMetaData = new PropertyMetaData();
 propertyMetaData.setName("bean");
 attribute.setPropertyMetaData(propertyMetaData);

 QName MODE = new QName("mode");
 attribute = beanType.getAttribute(MODE);
 ValueAdapter modeAdapter = new ValueAdapter()
 {
 public Object cast(Object o, Class c)
 {
 String string = (String) o;
 return new ControllerMode(string);
 }
 };
 attribute.setValueAdapter(modeAdapter);
 */
 beanType.setHandler(new DefaultElementHandler()
 {

 public Object startElement(Object parent, QName name, ElementBinding element)
 {
 return new AbstractBeanMetaData();
 }

 public void attributes(Object o, QName elementName, ElementBinding element, Attributes attrs, NamespaceContext nsCtx)
 {
 AbstractBeanMetaData bean = (AbstractBeanMetaData) o;
 for (int i = 0; i < attrs.getLength(); ++i)
 {
 String localName = attrs.getLocalName(i);
 if ("name".equals(localName))
 bean.setName(attrs.getValue(i));
 else if ("class".equals(localName))
 bean.setBean(attrs.getValue(i));
 else if ("mode".equals(localName))
 bean.setMode(new ControllerMode(attrs.getValue(i)));
 else if ("whenRequired".equals(localName))
 bean.set........
 }
 }
 });

 <xsd:complexType name="beanType">

Or do this

 public void attributes(Object o, QName elementName, ElementBinding element, Attributes attrs, NamespaceContext nsCtx)
 {
 AbstractDemandMetaData demand = (AbstractDemandMetaData) o;
 for (int i = 0; i < attrs.getLength(); ++i)
 {

 if ("whenRequired".equals(localName))
 demand.setWhenRequired(new ControllerState(attrs.getValue(i)));
