    • load

      @NotNull DataEntity load(@NotNull String path, @NotNull CancellationToken token) throws IOException, UnsupportedOperationException
      Returns the data resource loaded from the given path.

      The download process can be canceled by the means of the cancellation token. It is up to the implementer to verify that the cancellation token state is set to true during the operation. When it is set to true, it indicates that a resource is no longer needed. Throwing a java.util.concurrent.CancellationException then reports the load as canceled rather than as failed.

      Parameters:
      path - Path to the resource.
      token - Cancellation token.
      Returns:
      the data resources as DataEntity.
      Throws:
      IOException - when loading the data fails.
      UnsupportedOperationException - when the loader cannot handle the given path (for example, an unsupported scheme or protocol).
