[opencms-dev] why are the default collectors protected access?

[Mario Jäger]

Hello Tim,

if you want to use the default resource collector org.opencms.file.collectors.CmsDefaultResourceCollector.getAllInFolder 
you have to use the following code in your Jsp:

<cms:contentload collector="allInFolder" param="{VFS URI}|{Resource type}|{Count}"> 

        ...

</cms:contentload>  

  
The param attributes you still have to complete with your required values.

Analog thereto you can use all the default resource collectors in OpenCms. Only if 
these default resource collectors are not sufficient for your requirements it is 
necessary to write your own resource collector. To write your own resource 
collector you have to implement the interface org.opencms.file.collectors.I_CmsResourceCollector.

Kind Regards,
Mario.
