      public SimpleContext(String sTenant, ContainerAdapter adapter)

  • Method Details

    • getDomainPartition

      public String getDomainPartition()
      Description copied from interface: ContainerContext
      Obtain the Domain Partition name associated with this ContainerContext.

      Note, that to get the name of the GLOBAL DomainPartition, the caller should do the following: 

          getGlobalContext().getDomainPartition();

      Specified by:
      getDomainPartition in interface ContainerContext
      Returns:
      the Domain Partition name or null if the container does not support Multi-Tenancy or this feature is turned off

    • isGlobalDomainPartition

      public boolean isGlobalDomainPartition()
      Description copied from interface: ContainerContext
      Check whether or not the DomainPartition associated with this context is GLOBAL.

      Note, that this call is basically equivalent to the following: 

          equals(getGlobalContext());

      Specified by:
      isGlobalDomainPartition in interface ContainerContext
      Returns:
      true if the DomainPartition associated with this context is GLOBAL

    • getGlobalContext

      public ContainerContext getGlobalContext()
      Description copied from interface: ContainerContext
      Obtain the ContainerContext associated with GLOBAL Domain Partition.

      Important note: since the ContainerContext object could use the context as a part of the event dispatcher or listener identity, it's imperative for the container to maintain no more than one instance of the global context.

      Specified by:
      getGlobalContext in interface ContainerContext
      Returns:
      the ContainerContext associated with the GLOBAL Domain Partition.

    • getCurrentThreadContext

      public ContainerContext getCurrentThreadContext()
      Description copied from interface: ContainerContext
      Obtain the ContainerContext associated with the current thread. Note, that the returned context could only be one of
      • null, if the current thread is not associated with any context;
      • the GLOBAL context;
      • this ContainerContext;
      • another instance of ContainerContext representing the same Domain Partition as this context.
      Note2: since the ContainerContext object could use the context as a part of the event dispatcher or listener identity, it's imperative for the container to maintain no more than one instance of the context per distinct Domain Partition per application.
      Specified by:
      getCurrentThreadContext in interface ContainerContext
      Returns:
      the ContainerContext associated with the current thread or null if the thread has no association

    • resetCurrentThreadContext

      public void resetCurrentThreadContext()
      Description copied from interface: ContainerContext
      Reset the execution context for the calling thread to be associated with this ContainerContext's Domain Partition. This method should only be called if the thread context was changed using ContainerContext.setCurrentThreadContext().
      Specified by:
      resetCurrentThreadContext in interface ContainerContext

    • setCurrentThreadContext

      public void setCurrentThreadContext()
      Description copied from interface: ContainerContext
      Set the execution context for the calling thread to be associated with this ContainerContext's Domain Partition.

      Note, that to set the execution context as GLOBAL, the caller should do the following: 

          getGlobalContext().setCurrentThreadContext();

      Specified by:
      setCurrentThreadContext in interface ContainerContext

    • runInDomainPartitionContext

      public <V> V runInDomainPartitionContext(Callable<V> action)
      Description copied from interface: ContainerContext
      Call the specified action in the context of the associated Domain Partition.

      Note, that to call the action in the GLOBAL context, the caller should do the following: 

          getGlobalContext().runInDomainPartitionContext(action);

      Specified by:
      runInDomainPartitionContext in interface ContainerContext
      Type Parameters:
      V - the result type of the action
      Parameters:
      action - the action to call
      Returns:
      the result of the Callable action

    • isCacheShared

      public boolean isCacheShared(String sCache)
      Description copied from interface: ContainerContext
      Check whether or not the cache with the specified name should be shared across various Domain Partitions.
      Specified by:
      isCacheShared in interface ContainerContext
      Parameters:
      sCache - the cache name
      Returns:
      true iff the specified cache should be shared

    • getCacheAttribute

      public Object getCacheAttribute(String sCache, String sAttribute)
      Description copied from interface: ContainerContext
      Obtain a value for a configuration attribute for a given cache.
      Specified by:
      getCacheAttribute in interface ContainerContext
      Parameters:
      sCache - the cache name
      sAttribute - the attribute name
      Returns:
      the specified attribute value or null, if the default value should be used

    • getSharedCaches

      public Set<String> getSharedCaches()
      Description copied from interface: ContainerContext
      Get a set of names for all shared caches. Those names will be used to start corresponding cache services during application activation.
      Specified by:
      getSharedCaches in interface ContainerContext
      Returns:
      the set of shared cache names

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • evaluateAttribute

      protected String evaluateAttribute(String sCache, String sAttribute)
      Get the value for a given macro attribute for a given cache mapping.
