# ContainerPropertyBag<TContainer>

> Base class for implementing a static property bag for a specified container type. This is an abstract class.

## Definition

* **Type:** Class
* **Namespace:** [Unity.Properties](/engine/6000.0/script-reference/unity/properties.md)
* **Assembly:** UnityEngine.PropertiesModule
* **Inherits from:** [PropertyBag\<T>](/engine/6000.0/script-reference/unity/properties/propertybag1.md)
* **Implements:** [IPropertyBag\<T>](/engine/6000.0/script-reference/unity/properties/ipropertybag1.md), [IPropertyBag](/engine/6000.0/script-reference/unity/properties/ipropertybag.md), [INamedProperties\<T>](/engine/6000.0/script-reference/unity/properties/inamedproperties1.md)

```csharp
public abstract class ContainerPropertyBag<TContainer> : PropertyBag<TContainer>, IPropertyBag<TContainer>, IPropertyBag, INamedProperties<TContainer>
```

## Remarks

A [ContainerPropertyBag\<TContainer>](/engine/6000.0/script-reference/unity/properties/containerpropertybag1.md) is used to describe and traverse the properties for a specified `TContainer` type.

In order for properties to operate on a type, a [ContainerPropertyBag\<TContainer>](/engine/6000.0/script-reference/unity/properties/containerpropertybag1.md) must exist and be pre-registered for that type.

*NOTE* In editor use cases property bags can be generated dynamically through reflection. (see Unity.Properties.Reflection)
