Interface StreamableIterable<T>

All Superinterfaces:

java.lang.Iterable<T>

Deprecated.

Deprecated in favour of FastStream. FastStream should be a drop-in replacement for StreamableIterable, however, it is recommended to switch to using Iterable.forEach(java.util.function.Consumer<? super T>) where possible.

@Deprecated
public interface StreamableIterable<T>
extends java.lang.Iterable<T>

An iterable capable of stream-like operations.

Whilst the Stream API is nice for some operations. There are some use cases where a simpler wrapped Iterable approach would be faster and more memory efficient, that's what this class aims to solve.
