ForEach vs Splitter in mule

This example app will show the difference between Foreach and splitter in Mule version 3.x. Collection splitter splits the incoming collection object and then you have to put a aggregator to collect the resultant objects. For each scope is a scope which does not change the payload and you get the same collection object once for each loop completes.

<mule xmlns:vm="" xmlns:http="" xmlns="" xmlns:doc=""
    <http:listener-config name="HTTP_Listener_Configuration" host="" port="8081" doc:name="HTTP Listener Configuration"/>
    <flow name="foreachtestFlow">
        <http:listener config-ref="HTTP_Listener_Configuration" path="/test" allowedMethods="GET" doc:name="HTTP"/>
        <component class="foreachexample.CollectionPayloadComponent" doc:name="Java"/>
        <!-- <foreach doc:name="For Each">
         <choice doc:name="Choice">
         <when expression="#[payload == 'foreach']">
          <set-session-variable value="foreachVar" variableName="test" doc:name="Session Variable"></set-session-variable>
          <set-session-variable value="BBQVar" variableName="test" doc:name="Session Variable"></set-session-variable>
         <flow-ref name="flow3" doc:name="Flow Reference"/>
        </foreach> -->
        <collection-splitter />
        <logger message="payload is : #[payload]" level="ERROR"/>
         <when expression="#[payload == 'foreach']">
          <set-session-variable value="foreachVar" variableName="test"></set-session-variable>
          <set-session-variable value="BBQVar" variableName="test"></set-session-variable>
        <flow-ref name="flow3" />
   <set-payload value="dsadasd"/>        
    <flow name="flow2">
        <vm:inbound-endpoint path="foreach" doc:name="VM"/>
        <logger message=" session var value is #[sessionVars.test] and payload is #[payload]" level="ERROR" doc:name="Logger"/>

 <flow name="flow3">
        <vm:outbound-endpoint path="foreach" doc:name="VM"/>
