From: Aline Manera <alinefm@br.ibm.com> The model implementation for config and its sub-resources were added to model_/config.py It is needed to create a temporary module named model_ as there is already a model.py in Kimchi code. It will be rename later when removing model.py Signed-off-by: Aline Manera <alinefm@br.ibm.com> --- src/kimchi/basemodel.py | 8 ++++ src/kimchi/model_/config.py | 87 +++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 95 insertions(+) create mode 100644 src/kimchi/model_/config.py diff --git a/src/kimchi/basemodel.py b/src/kimchi/basemodel.py index 285e86d..0058dc2 100644 --- a/src/kimchi/basemodel.py +++ b/src/kimchi/basemodel.py @@ -45,3 +45,11 @@ class BaseModel(object): for member_name in callables: m = getattr(model_instance, member_name, None) setattr(self, '%s_%s' % (method_prefix, member_name), m) + + +class Singleton(type): + _instances = {} + def __call__(cls, *args, **kwargs): + if cls not in cls._instances: + cls._instances[cls] = super(Singleton, cls).__call__(*args, **kwargs) + return cls._instances[cls] diff --git a/src/kimchi/model_/config.py b/src/kimchi/model_/config.py new file mode 100644 index 0000000..933e37f --- /dev/null +++ b/src/kimchi/model_/config.py @@ -0,0 +1,87 @@ +# +# Project Kimchi +# +# Copyright IBM, Corp. 2013 +# +# Authors: +# Aline Manera <alinefm@linux.vnet.ibm.com> +# +# This library is free software; you can redistribute it and/or +# modify it under the terms of the GNU Lesser General Public +# License as published by the Free Software Foundation; either +# version 2.1 of the License, or (at your option) any later version. +# +# This library is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
