• I have checked that the SDK documentation and API documentation doesn't solve my issue.

Description of the Issue

I am trying to retrieve the files with the associated metadata template within a folder with a single request to the Box API (through the Box Java SDK).
I am using the “fields” param in the following API request :

GET https://api.box.com/2.0/folders/<folderId>/items?fields=metadata.enterprise.<metadata_template_name>,modified_at,name,size

I found out in the Box Java SDK the piece of code which is triggering the above request :

String fields = "metadata.enterprise.<metadata_template_name>,modified_at,name,size";
for (BoxItem.Info itemInfo : boxFolder.getChildren(fields)) {
	// Do something
}

But… I did not find in the SDK a straightforward way to read the JSON response.
We just need to read the "entries" list in the JSON response (files information + metadata) without having to send additional requests to the Box API for performance optimization purposes.

What we don't want to do

for (BoxItem.Info itemInfo : boxFolder.getChildren(fields)) {
	if (itemInfo instanceof BoxFile.Info) {
		BoxFile file = ((BoxFile.Info) itemInfo).getResource();
		BoxFile.Info fileInfo = file.getInfo(); // <--- This line causes a new request to the Box API and we want to avoid that.
	}
}

Versions Used

Java Box SDK: 2.9.0
Java: 1.8

Questions

Am I supposed to use the BoxAPIRequest and BoxAPIResponse classes directly ?
Is there another way to avoid doing it manually ?

Thanks for your help.
