Type parameters
B
the element type of the returned collection.
Value parameters
f
the function to apply to each element.
Attributes
Returns
a new collection resulting from applying the given collection-valued function f to each element of the filtered outer collection and concatenating the results.

Applies a function f to all elements of the filtered outer collection.
Applies a function f to all elements of the filtered outer collection.
Type parameters
U
the type parameter describing the result of function f. This result will always be ignored. Typically U is Unit, but this is not necessary.
Value parameters
f
the function that is applied for its side-effect to every element. The result of function f is discarded.
