# asCollection method

ResolvableType asCollection()

Returns this type as a resolvable Iterable type.

This convenience method attempts to view this ResolvableType as an Iterable. If this type implements or extends Iterable, it returns the appropriate ResolvableType. Otherwise, it returns ResolvableType.NONE.

Returns:

- ResolvableType representing this type as an Iterable
- ResolvableType.NONE if this type is not iterable

Example:

    final listType = ResolvableType.forClass(List<String>);
    final setType = ResolvableType.forClass(Set<int>);
    final stringType = ResolvableType.forClass(String);

    final listAsCollection = listType.asCollection();
    print(listAsCollection != ResolvableType.NONE); // true

    final setAsCollection = setType.asCollection();
    print(setAsCollection != ResolvableType.NONE); // true

    final stringAsCollection = stringType.asCollection();
    print(stringAsCollection == ResolvableType.NONE); // true

    // Useful for generic collection processing
    void processIfIterable(ResolvableType type) {
      final asCollection = type.asCollection();
      if (asCollection != ResolvableType.NONE) {
        print("Can iterate over this type");
        // Process as iterable
      }
    }

## Implementation

    ResolvableType asCollection() => as(Iterable);
