+ A little more on Wite Tap
+
+
+ One of the common misconception about the wire tap and some time other similar components ()
+ that they are asynchronous in nature. Wire-tap as a component is neither sync nor async.
+ In fact non of the components in SI are sync or async except for. . . well read on.
+
+ What makes certain parts of the message flow sync or async is the Message Channel
+ abstraction. That is why from the inception of the framework we always emphasize the need and the value of the Message Channel
+ and that is why Spring Integration is the only framework at the time of writing where Message Channel
+ is a "first class citizen" of the framework (not an internal realization of EIP pattern) fulle exposed to you - the end user.
+
+ So, Wire-tap component is ONLY responsible to perform the following 3 tasks:
+
+
+ wire-tap into a message flow by tapping into a channel (e.g., channelA)
+
+
+ grab a copy of a message
+
+
+ send it to another channel (e.g., channelB)
+
+
+
+
+ Look at it as a variation of the Bridge (nothing more). But by bridging one channel with another wire-tap is essentially
+ initiates (forks) another message flow. Is this flow synchronous or asynchronous?
+ That is the ultimate question and the answer simply depends on the type of Message Channel 'channelB' is.
+ And as you know we have: Direct Channel, Pollable Channel and Executor Channel.
+ The last two do break the thread boundary making communication via such channels asynchronous simply because
+ the dispatching of the message from the channel happens on the different thread then the one that sent the message to that channel
+ and that is what is going to make your wire-tap flow sync or async.
+ It is consistent with other components within the framework (e.g., Message Publisher) and if you think about it its in a way
+ brings a level of simplicity by sparing you form worrying in advance (other then writing thread safe code) wether a
+ particular piece of code should be implemented as sync or async. In fact its always neither,
+ the code is just a function. The actual wiring of two pieces of code (component A and component B) via Message Channel
+ is what's going to make their collaboration sync or async. You may even want to change
+ from sync to async in the future and Message Channel is what's going
+ to allow you to do it swiftly without ever touching the code
