Class Method

 

Called after the template stream has been completely parsed.

This class method should return a (directive, stream) tuple. If directive is not None, it should be an instance of the Directive class, and gets added to the list of directives applied to the substream at runtime. stream is an event stream that replaces the original stream associated with the directive.

Parameters:
  • template - the Template object
  • stream - the event stream associated with the directive
  • value - the argument value for the directive; if the directive was specified as an element, this will be an Attrs instance with all specified attributes, otherwise it will be a unicode object with just the attribute value
  • namespaces - a mapping of namespace URIs to prefixes
  • pos - a (filename, lineno, offset) tuple describing the location where the directive was found in the source
Overrides: Directive.attach
(inherited documentation)

__call__(self, stream, directives, ctxt, **vars)
(Call operator)

 
Apply the directive to the given stream.
Parameters:
  • stream - the event stream
  • directives - a list of the remaining directives that should process the stream
  • ctxt - the context data
  • vars - additional variables that should be made available when Python code is executed
Overrides: Directive.__call__
(inherited documentation)

__repr__(self)
(Representation operator)

 
repr(x)
Overrides: object.__repr__
(inherited documentation)
