    • ExpressionPresenter

      public ExpressionPresenter(Configuration config)
      Make an ExpressionPresenter that writes indented output to the standard error output destination of the Configuration
      Parameters:
      config - the Saxon configuration

    • ExpressionPresenter

      public ExpressionPresenter(Configuration config, OutputStream out)
      Make an ExpressionPresenter that writes indented output to a specified output stream
      Parameters:
