# findInterfaces<I> abstract method

List<Class<I>> findInterfaces<I>(

1. Class parentClass, [
2. bool declared = true

])

Finds all interfaces implemented by the specified class with caching.

{@template class_loader_find_interfaces_as} Parameters:

- `parentClass`: The class to find interfaces for
- `declared`: Whether to include inherited interfaces (default: true)

Returns:

- List of implemented interfaces
- Empty list if no interfaces are implemented
- Cached results for subsequent calls

## Interface Resolution

- Transitive (default): Includes interfaces from superclasses and mixins
- Direct only: Only interfaces explicitly declared on this class

## Example

    final listClass = await loader.loadClass<List>('dart:core/list.dart.List');
    final interfaces = await loader.findInterfaces(listClass);
    // Returns: [Iterable, Collection, etc.]

    // Direct interfaces only
    final directInterfaces = await loader.findInterfaces(listClass, false);

## Caching Behavior

- Separate caches for transitive and direct interface queries
- Cache keys include the transitive flag for proper segregation
- Automatic cache invalidation on class hierarchy changes {@endtemplate}

## Implementation

    List<Class<I>> findInterfaces<I>(Class parentClass, [bool declared = true]);
