"""Mixin class for representing OCI resource/service with OCI client.
Most OCI requests requires a client for making the connection.
Usually the same client will be used for the requests related the same resource/service type.
This Mixin adds a "client" property to simplify accessing the client.
The actual client will be initialize lazily so that it is not required for a sub-class
To use the client, sub-class should override the init_client() method pass in the "client" keyword argument.
For example:
@class_or_instance_method
def init_client(cls, **kwargs) -> oci.logging.LoggingManagementClient:
return cls._init_client(client=oci.logging.LoggingManagementClient, **kwargs)
Instance methods in the sub-class can use self.client to access the client.
The init_client() method is a class method used to create the client.
Any class method using the client should use init_client() to create the client.
The call to this method may come from an instance or a class.
When the method is called from a class,
the default authentication configured at ADS level with ads.set_auth() will be used.
When the method is called from an instance,
the config, signer and kwargs specified when initializing the instance will be used.
The sub-class's __init__ method should take config, signer and client_kwargs as argument,
then pass them to the __init__ method of this class.
This allows users to override the authentication and client initialization parameters.
For example, log_group = OCILogGroup(config=config, signer=signer, client_kwargs=kwargs)

class OCIModelMixin(OCISerializableMixin):
"""Mixin class to operate OCI model.
OCI resources are represented by models in the OCI Python SDK.
Unifying OCI models for the same resource
-----------------------------------------
OCI SDK uses different models to represent the same resource for different operations.
For example, CreateLogDetails is used when creating a log resource,
while LogSummary is returned when listing the log resources.
However, both CreateLogDetails and LogSummary have the same commonly used attribute like
compartment_id, display_name, log_type, etc.
In general, there is a class with a super set of all properties.
For example, the Log class contains all properties of CreateLogDetails and LogSummary,
as well as other classes representing an OCI log resource.
A subclass can be implemented with this Mixin to unify the OCI models,
so that all properties are available to the user.
For example, if we define the Mixin model as ``class OCILog(OCIModelMixin, oci.logging.models.Log)``,
users will be able to access properties like ``OCILog().display_name``
Since this sub-class contains all the properties, it can be converted to any related OCI model in an operation.
For example, we can create ``CreateLogDetails`` from ``OCILog`` by extracting a subset of the properties.
When listing the resources, properties from ``LogSummary`` can be used to update
the corresponding properties of ``OCILog``.
Such convertion can be done be the generic methods provided by this Mixin.
Although OCI SDK accepts dictionary (JSON) data instead of objects like CreateLogDetails when creating or
updating the resource, the structure and keys of the dictionary is not easy for a user to remember.
It is also unnecessary for the users to construct the entire dictionary if they only want to update a single value.
This Mixin class should be the first parent as the class from OCI SDK does not call ``super().__init__()``
in its ``__init__()`` constructor.
Mixin properties may not be intialized correctly if ``super().__init__()`` is not called.
Provide generic methods for CRUDL operations
--------------------------------------------
Since OCI SDK uses different models in CRUDL operations,
this Mixin provides the following method to convert between them.
An OCI model instance can be any OCI model of the resource containing some properties, e.g. LogSummary
``from_oci_model()`` static method can be used to initialize a new instance from an OCI model instance.
``update_from_oci_model()`` can be used to update the existing properties from an OCI model instance.
``to_oci_model()`` can be used to extract properties from the Mixin model to OCI model.
