Method Details
-
toAdvancedMessage
Description copied from interface:MessageSafely convert thisMessageinstance into anAdvancedMessagereference which can offer more low level APIs to an experienced client user.The default implementation first checks if the current instance is already of the correct type before performing a brute force conversion of the current message to the client's own internal
AdvancedMessageimplementation. Users should override this method if the internal conversion implementation is insufficient to obtain the proper message structure to encode a meaningful 'on the wire' encoding of their custom implementation.- Specified by:
toAdvancedMessagein interfaceMessage<E>- Returns:
- a
AdvancedMessagethat contains this message's current state.
-
create
Creates an emptyClientMessageinstance.- Type Parameters:
V- The type of the body value carried in this message.- Returns:
- a new empty
ClientMessageinstance.
-
create
Creates anClientMessageinstance with the given bodySectionvalue.- Type Parameters:
V- The type of the body value carried in this message body section.- Parameters:
body- The bodySectionto assign to the created message instance.- Returns:
- a new
ClientMessageinstance with the given body.
-
createAdvancedMessage
Creates an emptyClientMessageinstance.- Type Parameters:
V- The type of the body value carried in this message.- Returns:

ClientMessageinstance.
-
durable
public boolean durable()Description copied from interface:MessageFor an message being sent this method returns the current state of the durable flag on the message. For a received message this method returns the durable flag value at the time of sending (or false if not set) unless the value is updated after being received by the receiver. -
durable
Description copied from interface:MessageControls if the message is marked as durable when sent. -
priority
public byte priority() -
priority
Description copied from interface:MessageSets the relative message priority. Higher numbers indicate higher priority messages. Messages with higher priorities MAY be delivered before those with lower priorities. For a received message this overwrites any value that was set by the remote sender. -
timeToLive
public long timeToLive()- Specified by:
timeToLivein interfaceMessage<E>- Returns:
- the currently set Time To Live duration (milliseconds).
-
timeToLive
Description copied from interface:MessageSets the message time to live value.The time to live duration in milliseconds for which the message is to be considered "live". If this is set then a message expiration time will be computed based on the time of arrival at an intermediary. Messages that live longer than their expiration time will be discarded (or dead lettered). When a message is transmitted by an intermediary that was received with a time to live, the transmitted message's header SHOULD contain a time to live that is computed as the difference between the current time and the formerly computed message expiration time, i.e., the reduced time to live, so that messages will eventually die if they end up in a delivery loop.
- Specified by:
timeToLivein interfaceMessage<E>- Parameters:
timeToLive- The time span in milliseconds that this message should remain live before being discarded.- Returns:
- this
Messageinstance.
-
firstAcquirer

- Specified by:
firstAcquirerin interfaceMessage<E>- Parameters:
firstAcquirer- The boolean value to assign to the first acquirer field of the message.- Returns:
- this
Messageinstance.
-

deliveryCountin interfaceMessage<E>- Returns:
- the number of failed delivery attempts that this message has been part of.
-
deliveryCount
Description copied from interface:MessageSets the value to assign to the delivery count field of thisMessage.Delivery count is the number of unsuccessful previous attempts to deliver this message. If this value is non-zero it can be taken as an indication that the delivery might be a duplicate. On first delivery, the value is zero. It is incremented upon an outcome being settled at the sender, according to rules defined for each outcome.
- Specified by:
deliveryCountin interfaceMessage<E>- Parameters:
deliveryCount- The new delivery count value to assign to this message.- Returns:
- this
Messageinstance.
-
messageId
-
messageId
Description copied from interface:MessageSets the message Id value to assign to thisMessage.The message Id, if set, uniquely identifies a message within the message system. The message producer is usually responsible for setting the message-id in such a way that it is assured to be globally unique. A remote peer MAY discard a message as a duplicate if the value of the message-id matches that of a previously received message sent to the same node.
-
userId
public byte[] userId() -
userId
Description copied from interface:MessageSets the user Id value to assign to thisMessage.The identity of the user responsible for producing the message. The client sets this value, and it MAY be authenticated by intermediaries.
-

-
subject
-
subject
Description copied from interface:MessageSets the subject value to assign to thisMessage.A common field for summary information about the message content and purpose.
-
replyTo
-
replyTo
Description copied from interface:MessageSets the replyTo value to assign to thisMessage.The address of the node to send replies to.

- Specified by:
correlationIdin interfaceMessage<E>- Returns:
- the currently assigned correlation ID or null if none set.
-
correlationId
Description copied from interface:MessageSets the correlationId value to assign to thisMessage.This is a client-specific id that can be used to mark or identify messages between clients.
- Specified by:
correlationIdin interfaceMessage<E>- Parameters:
correlationId- The correlationId value to assign to thisMessageinstance.- Returns:

Messageinstance.
-
contentType
- Specified by:
contentTypein interfaceMessage<E>- Returns:
- the assigned content type value for the message body section or null if not set.
-
contentType
Description copied from interface:MessageSets the contentType value to assign to thisMessage.The RFC-2046 MIME type for the message's application-data section (body). As per RFC-2046 this can contain a charset parameter defining the character encoding used: e.g., 'text/plain; charset="utf-8"'.
For clarity, as per section 7.2.1 of RFC-2616, where the content type is unknown the content-type SHOULD NOT be set. This allows the recipient the opportunity to determine the actual type. Where the section is known to be truly opaque binary data, the content-type SHOULD be set to application/octet-stream.
When using an application-data section with a section code other than data, content-type SHOULD NOT be set.
- Specified by:
contentTypein interfaceMessage<E>- Parameters:
contentType- The contentType value to assign to thisMessageinstance.- Returns:
- this
Messageinstance.
-
contentEncoding
- Specified by:
contentEncodingin interfaceMessage<E>- Returns:
- the assigned content encoding value for the message body section or null if not set.
-
contentEncoding
Description copied from interface:MessageSets the contentEncoding value to assign to thisMessage.The content-encoding property is used as a modifier to the content-type. When present, its value indicates what additional content encodings have been applied to the application-data, and thus what decoding mechanisms need to be applied in order to obtain the media-type referenced by the content-type header field.
Content-encoding is primarily used to allow a document to be compressed without losing the identity of its underlying content type.
Content-encodings are to be interpreted as per section 3.5 of RFC 2616 [RFC2616]. Valid content-encodings are registered at IANA [IANAHTTPPARAMS].
The content-encoding MUST NOT be set when the application-data section is other than data. The binary representation of all other application-data section types is defined completely in terms of the AMQP type system.
Implementations MUST NOT use the identity encoding. Instead, implementations SHOULD NOT set this property. Implementations SHOULD NOT use the compress encoding, except as to remain compatible with messages originally sent with other protocols, e.g. HTTP or SMTP.
Implementations SHOULD NOT specify multiple content-encoding values except as to be compatible with messages originally sent with other protocols, e.g. HTTP or SMTP.

contentEncodingin interfaceMessage<E>- Parameters:
contentEncoding- The contentEncoding value to assign to thisMessageinstance.- Returns:
- this
Messageinstance.
