OutgoingMessageQueueImpl
Create a new outgoing message queue.- Parameters:
stream_encoder
- default message encoder
-
-
Method Details
-
setTransport
- Specified by:
setTransport
in interfaceOutgoingMessageQueue
-
getMssSize
public int getMssSize()- Specified by:
getMssSize
in interfaceOutgoingMessageQueue
-
setEncoder
Set the message stream encoder that will be used to encode outgoing messages.- Specified by:
setEncoder
in interfaceOutgoingMessageQueue
- Parameters:
stream_encoder
- to use
-
getEncoder
- Specified by:
getEncoder
in interfaceOutgoingMessageQueue
-
getCurrentMessageProgress
public int[] getCurrentMessageProgress()- Specified by:
getCurrentMessageProgress
in interfaceOutgoingMessageQueue
- Returns:
- [ total, done] or null
-
destroy
public void destroy()Destroy this queue; i.e. perform cleanup actions.- Specified by:
destroy
in interfaceOutgoingMessageQueue
-
getTotalSize
public int getTotalSize()Get the total number of bytes ready to be transported.- Specified by:
getTotalSize
in interfaceOutgoingMessageQueue
- Returns:
- total bytes remaining
-
getDataQueuedBytes
public int getDataQueuedBytes()- Specified by:
getDataQueuedBytes
in interfaceOutgoingMessageQueue
-
getProtocolQueuedBytes
public int getProtocolQueuedBytes()- Specified by:
getProtocolQueuedBytes
in interfaceOutgoingMessageQueue
-
getPriorityBoost
public boolean getPriorityBoost()- Specified by:
getPriorityBoost
in interfaceOutgoingMessageQueue
-
setPriorityBoost
public void setPriorityBoost(boolean boost) - Specified by:
setPriorityBoost
in interfaceOutgoingMessageQueue
-
isBlocked
public boolean isBlocked()- Specified by:
isBlocked
in interfaceOutgoingMessageQueue
-
hasUrgentMessage
public boolean hasUrgentMessage()Whether or not an urgent message (one that needs an immediate send, i.e. a no-delay message) is queued.- Specified by:
hasUrgentMessage
in interfaceOutgoingMessageQueue
- Returns:
- true if there's a message tagged for immediate write
-
peekFirstMessage
- Specified by:
peekFirstMessage
in interfaceOutgoingMessageQueue
-
addMessage
Add a message to the message queue. NOTE: Allows for manual listener notification at some later time, using doListenerNotifications(), instead of notifying immediately from within this method. This is useful if you want to invoke listeners outside of some greater synchronised block to avoid deadlock.- Specified by:
addMessage
in interfaceOutgoingMessageQueue
- Parameters:
message
- message to addmanual_listener_notify
- true for manual notification, false for automatic
-
removeMessagesOfType
Remove all messages of the given types from the queue. NOTE: Allows for manual listener notification at some later time, using doListenerNotifications(), instead of notifying immediately from within this method. This is useful if you want to invoke listeners outside of some greater synchronised block to avoid deadlock.- Specified by:
removeMessagesOfType
in interfaceOutgoingMessageQueue
- Parameters:
message_types
- type to removemanual_listener_notify
- true for manual notification, false for automatic
-
removeMessage
Remove a particular message from the queue. NOTE: Only the original message found in the queue will be destroyed upon removal, which may not necessarily be the one passed as the method parameter, as some messages override equals() (i.e. BTRequest messages) instead of using reference equality, and could be a completely different object, and would need to be destroyed manually. If the message does not override equals, then any such method will likely *not* be found and removed, as internal queued object was a new allocation on insertion. NOTE: Allows for manual listener notification at some later time, using doListenerNotifications(), instead of notifying immediately from within this method. This is useful if you want to invoke listeners outside of some greater synchronised block to avoid deadlock.- Specified by:
removeMessage
in interfaceOutgoingMessageQueue
- Parameters:
message
- to removemanual_listener_notify
- true for manual notification, false for automatic- Returns:
- true if the message was removed, false otherwise
-
deliverToTransport
public int[] deliverToTransport(int max_bytes, boolean protocol_is_free, boolean manual_listener_notify) throws IOException Deliver (write) message(s) data to the underlying transport. NOTE: Allows for manual listener notification at some later time, using doListenerNotifications(), instead of notifying immediately from within this method. This is useful if you want to invoke listeners outside of some greater synchronised block to avoid deadlock.- Specified by:
deliverToTransport
in interfaceOutgoingMessageQueue
- Parameters:
max_bytes
- maximum number of bytes to delivermanual_listener_notify
- true for manual notification, false for automatic- Returns:
- number of bytes delivered
- Throws:
IOException
- on delivery error
-
flush
public void flush()Description copied from interface:OutgoingMessageQueue
Force all pending messages to be delivered- Specified by:
flush
in interfaceOutgoingMessageQueue
-
isDestroyed
public boolean isDestroyed()- Specified by:
isDestroyed
in interfaceOutgoingMessageQueue
-
doListenerNotifications
public void doListenerNotifications()Manually send any unsent listener notifications.- Specified by:
doListenerNotifications
in interfaceOutgoingMessageQueue
-
setTrace
public void setTrace(boolean on) - Specified by:
setTrace
in interfaceOutgoingMessageQueue
-
getQueueTrace
- Specified by:
getQueueTrace
in interfaceOutgoingMessageQueue
-
registerQueueListener
Add a listener to be notified of queue events.- Specified by:

in interfaceOutgoingMessageQueue
- Parameters:

-
-
cancelQueueListener
Cancel queue event notification listener.- Specified by:
cancelQueueListener
in interfaceOutgoingMessageQueue
- Parameters:
listener
-
-
notifyOfExternallySentMessage
Notifty the queue (and its listeners) of a message sent externally on the queue's behalf.- Specified by:
notifyOfExternallySentMessage
in interfaceOutgoingMessageQueue
