Class PendingConfigBeans

java.lang.Object
org.glassfish.admin.mbeanserver.PendingConfigBeans
All Implemented Interfaces:
org.glassfish.config.support.ConfigBeanListener, org.glassfish.hk2.api.PostConstruct, org.jvnet.hk2.config.TransactionListener
@Service(name="PendingConfigBeans") public class PendingConfigBeans extends Object implements org.glassfish.config.support.ConfigBeanListener, org.glassfish.hk2.api.PostConstruct, org.jvnet.hk2.config.TransactionListener
Called when ConfigBeans come into the habitat (see GlassfishConfigBean); a job queue is maintained for processing by the AMXConfigLoader, which is lazily loaded.

  • Constructor Details

    • PendingConfigBeans

      public PendingConfigBeans()
      /** Singleton: there should be only one instance and hence a private constructor. But the framework using this wants to instantiate things with a public constructor.

  • Method Details

    • size

      public int size()

    • postConstruct

      public void postConstruct()
      Specified by:
      postConstruct in interface org.glassfish.hk2.api.PostConstruct

    • take

      public PendingConfigBeanJob take() throws InterruptedException
      Throws:
      InterruptedException

    • peek

      public PendingConfigBeanJob peek() throws InterruptedException
      Throws:
      InterruptedException

    • onEntered

      public void onEntered(org.glassfish.hk2.api.ActiveDescriptor<org.jvnet.hk2.config.ConfigBean> provider)
      Specified by:
      onEntered in interface org.glassfish.config.support.ConfigBeanListener

    • add

      public PendingConfigBeanJob add(org.jvnet.hk2.config.ConfigBean cb, boolean useLatch)

    • remove

      public boolean remove(org.jvnet.hk2.config.ConfigBean cb)
      Removing a ConfigBean must ensure that all its children are also removed. This will normally happen if AMX is loaded as a side effect of unregistering MBeans, but if AMX has not loaded we must ensure it directly. This is all caused by an HK2 asymmetry that does not issue REMOVE events for children of removed elements.

      TODO: remove all children of the ConfigBean.

    • swapTransactionListener

      public void swapTransactionListener(org.jvnet.hk2.config.TransactionListener newListener)
      amx-impl has its own TransactionListener which takes over once AMX is loaded. Note that it is synchronized with transactionCommited() [sic] to avoid a race condition.

    • transactionCommited

      public void transactionCommited(List<PropertyChangeEvent> events)
      This is a workaround for the fact that the onEntered() is not being called in all cases, namely during deployment before AMX has loaded. See disableTransactionListener() above.

    • unprocessedTransactedEvents

      public void unprocessedTransactedEvents(List<org.jvnet.hk2.config.UnprocessedChangeEvents> changes)
