You can do this using TypoScript, since exactly this is the reason why
someone invented it: Configuring TYPO3 and it's extensions to do different
stuff in different situations.

myDefaultPage = PAGE
myDefaultPage.10 < plugins.tx_myext_pi1
myDefaultPage.10 {
    myTrigger = doThis
}

mySpecialPage = PAGE
mySpecialPage.typeNum = 99
mySpecialPage.10 < plugins.tx_myext_pi1
mySpecialPage.10 {
    myTrigger = doThat
}

In your plugin you will always get $content and $conf.
$conf is the array containing all the TypoScript stuff.

So in this case you could make a switch in PHP checking for the value of the
key myTrigger:

switch($conf['myTrigger']) {
    case 'doThis':
        $content = $this->doThis();
    break;
    case 'doThat':
        $content = $this->doThat();
    break;
    default:
        // Do nothing
}

So it's nmot up to your extension to "decide" in which context it is
"executed", its up to the TypoScript that is used to control your extension.

Reason: Somebody might use your extension for the same stuff but in another
context, and he might be using type 123 instead of 99. In this case your
approach won't work, while the TS approach does.
