Method Details

builder

static <T> MessageConfig.Builder<T> builder()

Create a new fluent API builder to customize configuration.

Type Parameters:

T - payload type

Returns:

a new builder

builder

static <T> MessageConfig.Builder<T> builder(MessageConfig<T> instance)

Create a new fluent API builder from an existing instance.

Type Parameters:

T - payload type

Parameters:

instance - an existing instance used as a base for the builder

Returns:

a builder based on an instance

entity

T entity()

Non-null message payload.

Returns:

payload

headers

List<MessageHeader> headers()

Ordered portable headers. Defaults to an empty list. Setting this option replaces the current entries; adding headers preserves their order and duplicate names. The builder accumulates entries in a mutable list and the prototype contains an immutable snapshot.

Returns:

portable headers

localMetadata

Map<String, MessageHeaderValue> localMetadata()

Metadata local to this message envelope. Defaults to an empty map. Setting this option replaces the current entries; adding a value replaces the value with the same exact name. The builder accumulates entries in a mutable map and the prototype contains an immutable snapshot. Local metadata remains in-process and is not part of portable headers or generic connector mapping.

Returns:

local metadata
