Netty 5.0.0.Alpha5 · io.netty5.handler.ssl.EngineWrapper

Used by SslHandler to wrap and unwrap Buffer instances, which requires them to be projected into ByteBuffers.

Instances of this class are single-threaded, and each SslHandler will have their own instance.

Field Summary

Modifier and Type	Field and Description
private ByteBuffer	cachedReadingBuffer
private ByteBuffer	cachedWritingBuffer
private static final ByteBuffer	EMPTY_BUFFER_DIRECT Used for handshakes with engines that require off-heap buffers.
private static final ByteBuffer	EMPTY_BUFFER_HEAP Used for handshakes with engines that require on-heap buffers.
private final SSLEngine	engine
private ByteBuffer[]	inputs
