Class MessageHeader

java.lang.Object

io.helidon.messaging.MessageHeader

public final class MessageHeader
extends Object

One immutable messaging header entry.

Header names are exact and case-sensitive. The core model does not impose a transport-specific name grammar; connectors validate names when mapping a message to their transport.
