<p class="MsoNormal">Hi,</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">Could somebody shed some lights on how the mentioned method
works ? What does it do exactly ? My best guess is it takes in a channel, a
string and does something to the string (escape the string ? split the string ?
or something like that? But why need a channel parameter?)</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">If there is already an explanation somewhere about this, please
point it out for me or possibly just tell me what configuration should I make
to trigger this method to be called. I can use debugger and figure it out by
myself.</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">Any help would be greatly appreciated.</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">Thanks very much</p>

<p class="MsoNormal"> </p>

<p class="MsoNormal">Regards</p>
