Internal method dispatcher for Microsoft Visual C/C++.
|
|
|
|
MSVC modules can register their module (register_modulename) and individual
|
|
classes (register_class) with the method dispatcher during initialization. MSVC
|
|
modules tend to be registered immediately after the Dispatcher import near the
|
|
top of the file. Methods in the MSVC modules can be invoked indirectly without
|
|
having to hard-code the method calls effectively decoupling the upstream module
|
|
with the downstream modules:
|
|
|
|
The reset method dispatches calls to all registered objects with a reset method
|
|
and/or a _reset method. The reset methods are used to restore data structures
|
|
to their initial state for testing purposes. Typically, this involves clearing
|
|
cached values.
|
|
|
|
The verify method dispatches calls to all registered objects with a verify
|
|
method and/or a _verify method. The verify methods are used to check that
|
|
initialized data structures distributed across multiple modules are internally
|
|
consistent. An exception is raised when a verification constraint violation
|
|
is detected. Typically, this verifies that initialized dictionaries support
|
|
all of the requisite keys as new versions are added.
