# componentType<C> abstract method

Class<C>? componentType<C>()

Gets the component type for collection-like generic classes.

Type Parameters:

- `C`: The expected component type for type safety

Returns:

- A Class<C> representing the element type
- `null` if type information is unavailable
- `Class<dynamic>` if not a collection-like type

Works with:

- Lists (`List<T>` → `T`)
- Sets (`Set<T>` → `T`)
- Maps (`Map<K,V>` → `V`)
- Other generic collections

## Implementation

    Class<C>? componentType<C>();
