|
|
it evaluates, on every matching object, a Python p_expression (which
|
|
may be an expression or a statement), and returns, if needed, a
|
|
result. The result may be initialized through parameter p_context.
|
|
p_expression is evaluated with 2 variables in its context: "obj"
|
|
which is the currently walked object, instance of p_klass, and "ctx",
|
|
which is the context as initialized (or not) by p_context. p_context
|
|
may be used as
|
|
(1) a variable or instance that is updated on every call to
|
|
produce a result;
|
|
(2) an input variable or instance;
|
|
(3) both.
|
|
|
|
The method returns p_context, modified or not by evaluation of
|
|
p_expression on every matching object.
