33 <p>The alive operation can used to see whether a given parallel test component is alive or not. It works similarly to the running operation, the difference is when used for alive parallel test
35 <p>Normal parallel test component is alive when it is running.
<code>vc_ptc.alive
</code> always returns the same value as
<code>vc_ptc.running
</code> if
<code>vc_ptc
</code> is a normal parallel
37 <p>Alive parallel test component is alive from the point of its first start until it is killed implicitely at MTC termination or explicitely using the kill operation.
39 <li>The operation does not block TTCN-
3 program execution, i.e., it reflects the momentary state of the parallel test component and does not wait for its termination.
</li>
40 <li>When the
<a href=
"all.html"><b><font face=
"Courier New" color=
"#003258" size=
"4">all
</font></b></a> keyword is used with the operation, it will return true if all parallel
41 test components started are executing their behavior.
</li>
42 <li>When the
<a href=
"any.html"><b><font face=
"Courier New" color=
"#003258" size=
"4">any
</font></b></a> keyword is used with the operation, it will return true if at least one
43 parallel test component is executing its behavior.
