public class SoBaseContextCache extends Inventor implements SafeDisposable
Base context dependent cache management class. A helper base class used to store context dependent cache objects.

  • Method Details

    • setContextDependent

      public void setContextDependent()
      Calls setContextDependent((boolean)true).

    • isDisposable

      public boolean isDisposable()
      Description copied from interface: SafeDisposable
      Returns a boolean flag which indicates if it is safe to call SafeDisposable.dispose() on the object.
      Specified by:
      isDisposable in interface SafeDisposable
      Returns:
      true if the object can be disposed in a safe manner

    • dispose

      public boolean dispose()
      Description copied from class: Inventor
      Explicitly call this method to force object to dispose its unmanaged resources. The object may not be reused in the application code after this call.
      Specified by:
      dispose in interface SafeDisposable
      Overrides:
      dispose in class Inventor
      Returns:
      true if this object native resources were successfully disposed; false if it was already disposed or no native resources has been registered for this object.

    • isContextDependent

      public boolean isContextDependent()
      return current context dependency state. (by default all caches are context dependent).

    • release

      public void release(SoDeviceContextSharedGroup name_8343)
      This function is called when a context has been requested to delete the context through the SoDeviceContext.dispose() method. As some object might be still attached, it triggers all attached object release() method to ask them to detach (and then get it refcount to zero).

    • setContextDependent

      public void setContextDependent(boolean flag)
      Object is considered not context dependent as long as SoDeviceContext was not ref by this object. Once at least one device is ref then it calls this function to enbale later check checks deleting this object. see (SoDeviceContext.checkRefIssue call in destructor).
