How HDScanner detects updated deployments

[vickyk]

I am trying to figure out how the modified deployments are updated in the MutableProfile when some of the existing deployment artifact is updated or new one is added to deploy directory.
Here is the code
https://anonsvn.jboss.org/repos/jbossas/branches/Branch_5_x/system/src/main/org/jboss/system/server/profileservice/hotdeploy/HDScanner.java
org.jboss.system.server.profileservice.hotdeploy.HDScanner::scan()

 MutableProfile activeProfile = (MutableProfile) profile;
 Collection<ModificationInfo> modifiedDeployments = activeProfile.getModifiedDeployments();

I have spend some time in going though the org.jboss.system.server.profileservice.repository.AbstractProfileService and org.jboss.system.server.profileservice.repository.ProfileContext but could not yet make out.

Any pointers?

The JBOSS_HOME/server/< servername>/conf/bootstrap/profile.xml has a DeploymentRepositoryFactory:

<!-- The default deployment repository factory -->
 <bean name="DefaultDeploymentRepositoryFactory" class="org.jboss.system.server.profileservice.repository.DefaultDeploymentRepositoryFactory">
 <property name="deploymentFilter"><inject bean="DeploymentFilter" /></property>
 <property name="checker"><inject bean="StructureModificationChecker" /></property>
 </bean>

https://anonsvn.jboss.org/repos/jbossas/branches/Branch_5_x/system/src/main/org/jboss/system/server/profileservice/repository/DefaultDeploymentRepositoryFactory.java

This creates a DeploymentRepository:

public DeploymentRepository createDeploymentRepository(ProfileKey key, ProfileSourceMetaData metaData)

The hotdeployment enabled repository is here https://anonsvn.jboss.org/repos/jbossas/branches/Branch_5_x/system/src/main/org/jboss/system/server/profileservice/repository/HotDeploymentRepository.java. The profile is associated with the deployment repository and that's where the call ends up when getModifiedDeployments() is invoked on the profile.
