YamlNode Implementation

This drb-driver-yaml module implements yaml format access with DRB data model. It is able to navigate among the yaml contents.

Yaml Factory and Yaml Node

The module implements the basic factory model defined in DRB in its node resolver. Based on the python entry point mechanism, this module can be dynamically imported into applications.

The entry point group reference is drb.driver.
The implementation name is yaml.
The factory class is encoded into drb.drivers.yaml:YamlNodeFactory.

The yaml factory creates a YamlNode from an existing yaml content. It uses a base node to access the content data using the streamed base node implementation.

The base node can be a FileNode (See drb-driver-file), HttpNode, ZipNode or any other node able to provide streamed (BufferedIOBase, RawIOBase, IO) yaml content.

limitations

The current version does not manage child modification and insertion. yamlNode is currently read only.

Using this module

To include this module into your project, the drb-driver-yaml module shall be referenced into requirement.txt file, or the following pip line can be run:

pip install drb-driver-yaml

Node Creation:

The implementation can create a yamlNode by giving the path to a yaml file:

from drb.drivers.yaml import YamlNode

node = YamlNode(PATH_yaml)

If the baseNode is an HttpNode, FileNode... the implementation can retrieve the data of your yaml with this:

from drb.drivers.yaml import YamlNodeFactory

FACTORY = YamlNodeFactory()
FILE_NODE = DrbFileNode(PATH_TO_YOUR_YAML)
NODE = FACTORY.create(FILE_NODE)
