Class ApplicationContext

java.lang.Object
org.jdesktop.application.AbstractBean
org.jdesktop.application.ApplicationContext
public class ApplicationContext extends AbstractBean
A singleton that manages shared objects, like actions, resources, and tasks, for Applications.

Applications use the ApplicationContext singleton to find global values and services. The majority of the Swing Application Framework API can be accessed through ApplicationContext. The static getInstance method returns the singleton Typically it's only called after the application has been launched, however it is always safe to call getInstance.

    • getApplicationClass

      public final Class getApplicationClass()
      Returns the application's class or null if the application hasn't been launched and this property hasn't been set. Once the application has been launched, the value returned by this method is the same as getApplication().getClass().
      Returns:
      the application's class or null
      See Also:

    • setApplicationClass

      public final void setApplicationClass(Class applicationClass)
      Called by Application.launch() to record the application's class.

      This method is only intended for testing, or design time configuration. Normal applications shouldn't need to call it directly.

      See Also:

    • getApplication

      public final Application getApplication()
      The Application singleton, or null if launch hasn't been called yet.
      Returns:
      the launched Application singleton.

    • getResourceManager

      public final ResourceManager getResourceManager()
      The application's ResourceManager provides read-only cached access to resources in ResourceBundles via the ResourceMap class.
      Returns:
      this application's ResourceManager.
      See Also:

    • setResourceManager

      protected void setResourceManager(ResourceManager resourceManager)
      Change this application's ResourceManager. An ApplicationContext subclass that wanted to fundamentally change the way ResourceMaps were created and cached could replace this property in its constructor.

      Throws an IllegalArgumentException if resourceManager is null.

      Parameters:
      resourceManager - the new value of the resourceManager property.
      See Also:

    • getResourceMap

      public final ResourceMap getResourceMap(Class cls)
      Returns a chain of two or more ResourceMaps. The first encapsulates the ResourceBundles defined for the specified class, and its parent encapsulates the ResourceBundles defined for the entire application.

      This is just a convenience method that calls ResourceManager.getResourceMap(). It's defined as: 

      return getResourceManager().getResourceMap(cls, cls);
      Parameters:
      cls - the class that defines the location of ResourceBundles
      Returns:
      a ResourceMap that contains resources loaded from ResourceBundles found in the resources subpackage of the specified class's package.
      See Also:

    • getResourceMap

      public final ResourceMap getResourceMap(Class startClass, Class stopClass)
      Returns a chain of two or more ResourceMaps. The first encapsulates the ResourceBundles defined for the all of the classes between startClass and stopClass inclusive. It's parent encapsulates the ResourceBundles defined for the entire application.

      This is just a convenience method that calls ResourceManager.getResourceMap(). It's defined as: 

      return getResourceManager().getResourceMap(startClass, stopClass);
      Parameters:
      startClass - the first class whose ResourceBundles will be included
      stopClass - the last class whose ResourceBundles will be included
      Returns:
      a ResourceMap that contains resources loaded from ResourceBundles found in the resources subpackage of the specified class's package.

    • getResourceMap

      public final ResourceMap getResourceMap()
      Returns the chain of ResourceMaps that's shared by the entire application, beginning with the one defined for the Application class, i.e. the value of the applicationClass property.

      This is just a convenience method that calls ResourceManager.getResourceMap(). It's defined as: 

      return getResourceManager().getResourceMap();
      Returns:
      the Application's ResourceMap

      See Also:

    • setActionManager

      protected void setActionManager(ActionManager actionManager)

      actionManager - the new value of the actionManager property.
