Class ConfigurationReadWriteDelegate

java.lang.Object

org.rhq.modules.plugins.jbossas7.ConfigurationReadWriteDelegate

All Implemented Interfaces:

ConfigurationFacet

public class ConfigurationReadWriteDelegate
extends Object
implements ConfigurationFacet

This is the special implementation of ConfigurationWriteDelegate which reads configuration from resource prior applying an update. This way it can apply only configuration difference. Currently only simple properties are supported. This delegate may not be used by default, because it creates additional load by reading configuration, but can be used in cases, when applying all config properties causes issues (for example EJB3 subsystem - where write to some attribute causes deployment restart - while user doing configuration change in different attribute does not expect/want deployments to restart)
