def remap_module(controller, module_id, pipeline, module_remap):
"""remap_module offers a method to shortcut the
specification of upgrades. It is useful when just changing
the names of ports or modules, but can also be used to add
intermediate modules or change the format of parameters. It
is usually called from handle_module_upgrade_request, and the
first three arguments are passed from the arguments to that
method.
module_remap specifies all of the changes and is of the format
{<old_module_name>: [(<start_version>, <end_version>,
<new_module_klass> | <new_module_id> | None,
<remap_dictionary>)]}
where new_module_klass is the class and new_module_id
is a string of the format
<package_name>:[<namespace> | ]<module_name>
passing None keeps the original name,
and remap_dictionary is {<remap_type>:
<name_changes>} and <name_changes> is a map from <old_name> to
<new_name> or <remap_function>
The remap functions are passed the old object and the new
module and should return a list of operations with elements of
the form ('add', <obj>).
For example:
def outputName_remap(old_conn, new_module):
ops = []
...
return ops
module_remap = {'FileSink': [(None, '1.5.1', FileSink,
{'dst_port_remap':
{'overrideFile': 'overwrite',
'outputName': outputName_remap},
'function_remap':
{'overrideFile': 'overwrite',
'outputName': 'outputPath'}}),
