Package conduit :: Module Module :: Class ModuleManager

Class ModuleManager

source code

Generic dynamic module loader for conduit. Given a path it loads all modules in that directory, keeping them in an internam array which may be returned via get_modules

Also manages dataprovider factories which make dataproviders available at runtime

source code

_emit_unavailable(self, dataproviderWrapper)

source code

_build_filelist_from_directories(self, directories=None)
Converts a given array of directories into a list containing the filenames of all qualified modules.

source code

_is_module(self, filename)

source code

_is_module_dir(self, dirname)

source code

_append_module(self, wrapper, klass)

source code

_remove_module(self, key)

source code

_import_file(self, filename)
Tries to import the specified file.

source code

_load_modules_in_file(self, filename)
Loads all modules in the given file

source code

load_all(self, whitelist, blacklist)
Loads all classes in the configured paths.

source code

conduit.ModuleManager.ModuleWrapper[]

get_all_modules(self)
Returns: All loaded modules

source code

get_modules_by_type(self, *type_filter)
Returns all loaded modules of type specified by type_filter or all if the filter is set to None.

source code

get_module_wrapper_with_instance(self, wrapperKey)
Returns a new ModuleWrapper with a dp instace described by wrapperKey

Method Details

[hide private]

init(self, dirs=None)
(Constructor)

source code

Parameters:

dirs (string[]) - A list of directories to search. Relative pathnames and paths containing ~ will be expanded. If dirs is None the ModuleLoader will not search for modules.

_build_filelist_from_directories(self, directories=None)

source code

Converts a given array of directories into a list containing the filenames of all qualified modules. Recurses into directories and adds files if they have the same name as the directory in which they reside. This method is automatically invoked by the constructor.

_remove_module(self, key)

source code

Looks for a given key in the class registry and attempts to remove it

Parameters:

key - The key of the class to remove

_import_file(self, filename)

source code

Tries to import the specified file. Returns the python module on succes. Primarily for internal use. Note that the python module returned may actually contain several more loadable modules.

load_all(self, whitelist, blacklist)

source code

Loads all classes in the configured paths.

If whitelist and blacklist are supplied then the name of the file is tested against them. Default policy is to load all modules unless

get_all_modules(self)

source code

Returns: conduit.ModuleManager.ModuleWrapper[]: All loaded modules

make_modules_callable(self, type_filter)

source code

If it is necesary to call the modules directly. This function creates those instances in wrappers of the specified type
