// CEventScriptHandler - Use or derive from this class to create a script
|
||
|
|
// handler for a specific sink.
|
||
|
|
//
|
||
|
|
// Usage: Use SetScript to pass the script to the script handler. You can
|
||
|
|
// make global variables available to your script by calling AddGlobalVariable.
|
||
|
|
// Use AddConnectionPoint to bind to specific functions within the script.
|
||
|
|
// Name the connection point Hello and the script parse will look for Hello_xxx
|
||
|
|
// functions and attempt to connect to them. Once you have set the script and
|
||
|
|
// any other options, you can call StartScript to cause the script to be loaded,
|
||
|
|
// parsed and intialized. Any global code in the script will be executed at this
|
||
|
|
// time. Use ExecuteConnectionPoint to cause a specific function to be executed.
