Send Action elements
The Send Action button 
can be used in statecharts,
activity diagrams, and flow charts to represent the sending events
to external entities.
The Send Action element can be used to specify the following actions:
- Event to send
- Event target
- Values for event arguments
This is a language-independent element, which is translated into the relevant implementation language during code generation.
Note: Code can be generated for Send Action elements
in C, C++, and Java.
