      • loadBundle

        public org.pentaho.reporting.libraries.resourceloader.ResourceBundleData loadBundle​(org.pentaho.reporting.libraries.resourceloader.ResourceManager resourceManager,
                                                                                            org.pentaho.reporting.libraries.resourceloader.ResourceKey key)
                                                                                     throws org.pentaho.reporting.libraries.resourceloader.ResourceLoadingException
        Tries to load the bundle. If the key does not point to a usable resource-bundle, this method returns null. The Exception is only thrown if the bundle is not readable because of IO-Errors.

        A resource-bundle loader should only load the bundle for the key itself, never for any of the derived subkeys. It is the ResourceManager's responsibility to search the key's hierachy for the correct key.

        Specified by:
        loadBundle in interface org.pentaho.reporting.libraries.resourceloader.ResourceBundleLoader
        Parameters:
        key - the resource key pointing to the bundle.
        Returns:
        the loaded bundle or null, if the resource was not understood.
        Throws:
        org.pentaho.reporting.libraries.resourceloader.ResourceLoadingException - if something goes wrong.
      • isSupportedKey

        public boolean isSupportedKey​(org.pentaho.reporting.libraries.resourceloader.ResourceKey key)
        Checks, whether this resource loader implementation was responsible for creating this key.
        Specified by:
        isSupportedKey in interface org.pentaho.reporting.libraries.resourceloader.ResourceBundleLoader
        Parameters:
        key - the key that should be tested.
        Returns:
        true, if the key is supported.
      • deriveKey

        public org.pentaho.reporting.libraries.resourceloader.ResourceKey deriveKey​(org.pentaho.reporting.libraries.resourceloader.ResourceKey parent,
                                                                                    String path,

                                                                             throws org.pentaho.reporting.libraries.resourceloader.ResourceKeyCreationException
        Derives a new resource key from the given key. If neither a path nor new factory-keys are given, the parent key is returned.
        Specified by:
        deriveKey in interface org.pentaho.reporting.libraries.resourceloader.ResourceBundleLoader
        Parameters:
        parent - the parent
        path - the derived path (can be null).
        factoryKeys - the optional factory keys (can be null).
        Returns:
        the derived key.
        Throws:
        org.pentaho.reporting.libraries.resourceloader.ResourceKeyCreationException - if the key cannot be derived for any reason.
