Examples of org.jboss.beans.metadata.spi.InstallMetaData

org.jboss.beans.metadata.spi.InstallMetaData
Metadata about an (un)installation method. The method will be called when the bean is installed (if this metadata is in the list returned by {@link BeanMetaData#getInstalls()}, or when the bean is uninstalled if it is in the list returned by {@link BeanMetaData#getUninstalls()}. Install methods can either exist on the bean owning this {@link InstallMetaData} oron another bean, in which case we will get a dependency on the other bean.
Normally (un)installation methods will be called when invoked upon installing to/uninstalling from the {@link ControllerState#INSTALLED} state, but this can be overridden by setting {@link #setState(ControllerState)} @author Adrian Brock @version $Revision: 90092 $
