c4d.BaseContainer

class c4d.BaseContainer
A container is a collection of individual values.
Each value has its own ID and type. Container can also carry any number of child containers.
There is no guarantee that a value is there in the container.
Keep in mind that there is no guarantee for a value to be in the container.
Use default values whenever possible when accessing the values.
Maybe your plugin won’t be able to change some values, but it will work anyway.
It is recommended that you use the available containers to store your own values as well.
That way they will be automatically saved.
However, if you want to store values in the top level of for example an object container, you’ll have to use a unique id.
You can use a plugin id from Plugin Café for this.
A good way is to store a sub-container with this id. Inside this sub-container you can use whatever ids you want.
Once you’ve set a container value using one type you must neither try to access it using another type, nor overwrite it with a value of another type!
Using the wrong access will not crash, but it is illegal.
