Interface HandlerContext.UnresolvedFuture

All Known Subinterfaces:

HandlerContext.UnresolvedFuture.AllOf, HandlerContext.UnresolvedFuture.AnyOf, HandlerContext.UnresolvedFuture.Combinator, HandlerContext.UnresolvedFuture.Mapped, HandlerContext.UnresolvedFuture.Single

Enclosing interface:

HandlerContext

public static sealed interface HandlerContext.UnresolvedFuture
permits HandlerContext.UnresolvedFuture.Single, HandlerContext.UnresolvedFuture.Mapped, HandlerContext.UnresolvedFuture.Combinator

Node of a future tree, awaited with HandlerContext.await(UnresolvedFuture). A node is either a HandlerContext.UnresolvedFuture.Single node, a HandlerContext.UnresolvedFuture.Mapped node, or a HandlerContext.UnresolvedFuture.Combinator node (HandlerContext.UnresolvedFuture.AnyOf or HandlerContext.UnresolvedFuture.AllOf).

The HandlerContext implementation reads the tree from another thread while HandlerContext.await(UnresolvedFuture) is in progress: the tree structure must not change, and isDone() must be safe to read from other threads.
