you can override this value to provide a more convenient name.
This is done in a few places in botocore (ses instead of email,
emr instead of elasticmapreduce). If this value is not provided,
it will default to the endpointPrefix defined in the model.

:type name: string
:param name: The operation name. This is the operation name exposed to
the users of this model. This can potentially be different from
the "wire_name", which is the operation name that *must* by
provided over the wire. For example, given::
"CreateCloudFrontOriginAccessIdentity":{
"name":"CreateCloudFrontOriginAccessIdentity2014_11_06",
...
}
The ``name`` would be ``CreateCloudFrontOriginAccessIdentity``,
but the ``self.wire_name`` would be
``CreateCloudFrontOriginAccessIdentity2014_11_06``, which is the
value we must send in the corresponding HTTP request.

This is a convenience builder class that makes it easy to construct
``StructureShape``s based on a denormalized model.
It will handle the details of creating unique shape names and creating
the appropriate shape map needed by the ``StructureShape`` class.
Example usage::
builder = DenormalizedStructureBuilder()
shape = builder.with_members({
'A': {
'type': 'structure',
'members': {
'B': {
'type': 'structure',
'members': {
'C': {
'type': 'string',
}
}
}
}
}
}).build_model()
# ``shape`` is now an instance of botocore.model.StructureShape
:type dict_type: class
:param dict_type: The dictionary type to use, allowing you to opt-in
to using OrderedDict or another dict type. This can
be particularly useful for testing when order
matters, such as for documentation.
