It stores the values passed to the template and also the names the template exports. Creating instances is neither supported nor useful as it's created automatically at various stages of the template evaluation and should not be created by hand. The context is immutable. Modifications on :attr:`parent` **must not** happen and modifications on :attr:`vars` are allowed from generated template code only. Template filters and global functions marked as :func:`pass_context` get the active context passed as first argument and are allowed to access the context read-only. The template context supports read only dict operations (`get`, `keys`, `values`, `items`, `iterkeys`, `itervalues`, `iteritems`, `__getitem__`, `__contains__`). Additionally there is a :meth:`resolve` method that doesn't fail with a `KeyError` but returns an :class:`Undefined` object for missing variables.
