See: Description

Interface Summary
Interface | Description
--- | ---
ConnectingIOReactor | ConnectingIOReactor represents an I/O reactor capable of establishing connections to remote hosts.
EventMask | Type of I/O event notifications I/O sessions can declare interest in.

## Package org.apache.http.nio.reactor Description

API for event driven NIO based on Doug Lea's reactor pattern. This API is not specific to HTTP communication. However, it is minimal in the sense that it defines only what is required within the scope of HTTP components.
