Class DeployableUnitDeployer  

java.lang.Object
  org.mobicents.slee.container.management.DeployableUnitDeployer

---

public class DeployableUnitDeployer

extends java.lang.Object

An instance of this class is created for every deployable unit that is installed in the slee. Use of this class goes through the static deploy. It then creates a UnitDeployer instance that corresponds the jar file passed to deploy.
