What are Extensions in - GlideScriptedExtensionPoint ?

[Raji10]

Hi All,

I just wanted to understand what does the method getExtensions returns in the GlideScriptedExtensionPoint?

Why the methods defined in the extension point has to run N number of times (Extensions)?

For example:

var eps = new GlideScriptedExtensionPoint().getExtensions("CanReserve");
			eps.forEach(function(ep)
						{
				if(ep.handles(thing))
					{
						canReserve = ep.canReserve(thing,from,until,by);
					}
			});

Thanks & Regards,

Raji.

Hi Both,

Thank you for your quick response, I have gone through these articles earlier to my question in the forum. My only doubt is what is the necessity of running all the extensions with the same name and then storing it in the same variable (Only the last extension will be stored in the ), you can refer to the below script, 

var eps = new GlideScriptedExtensionPoint().getExtensions("CanReserve");
			eps.forEach(function(ep)
						{
				if(ep.handles(thing))
					{
						canReserve = ep.canReserve(thing,from,until,by);
					}
			});

Thanks & Regards,

Raji.
