It works like the regular environment but tells the compiler to generate sandboxed code. Additionally subclasses of this environment may override the methods that tell the runtime what attributes or functions are safe to access. If the template tries to access insecure code a :exc:`SecurityError` is raised. However also other exceptions may occur during the rendering so the caller has to ensure that all exceptions are caught. t +t -t *t /s //s **t %c C s t S( s� Called during template compilation with the name of a unary operator to check if it should be intercepted at runtime. If this method returns `True`, :meth:`call_unop` is executed for this unary operator. The default implementation of :meth:`call_unop` will use the :attr:`unop_table` dictionary to perform the operator with the same logic as the builtin one. The following unary operators are interceptable: ``+`` and ``-`` Intercepted calls are always slower than the native operator call, so make sure only to intercept the ones you are interested in. .. versionadded:: 2.6 ( Rm ( R5 t operator( ( s= /opt/imh-python/lib/python2.7/site-packages/jinja2/sandbox.pyt intercept_unopA s c O sH t j | | | � t | j d <| j j � | _ | j j � | _ d S( Nt range( R R8 RT t globalst default_binop_tablet copyt binop_tablet default_unop_tablet unop_table( R5 R6 R7 ( ( s= /opt/imh-python/lib/python2.7/site-packages/jinja2/sandbox.pyR8 R s c C s | j d � p t | | � S( sY The sandboxed environment will call this method to check if the attribute of an object is safe to access.
