FQL and SpringSocialFacebook

[habuma]

These are all good things that you're pointing out. I'll look into this one...but it'd be helpful if you find things like this to open a bug in JIRA at https://jira.springsource.org/browse/SOCIALFB. Sometimes these comments in the forums get lost in all of the forum noise; but I notice open bugs in JIRA.

I will do that. I do like to take my time, make sure I understand the code and intent before adding a bug. Nobody wants JIRA full of hundreds of wish-list items.

Mostly about the getList() issue, but touches on the whole set of getXYZ issues.

Here is a possible modification to FqlResult, in the vein of FqlResultMapper:
If you need to map an array of primitives, like Integer, String, or Array, the existing FqlResultMapper will not suffice.
Class Cast Errors come out, since it tries to handle the data as a List of Map<String,Object>

Would a FqlValueMapper make sense?

public interface FqlValueMapper<T> {
    T mapObject(Object objectValue);
}

with a function in FqlResult like

public <T> List<T> getList(String fieldName, FqlValueMapper<T> mapper) {
    // get field as List<Object>, and iterate over each item, passing it to the FqlValueMaper
    ....
}

This would let us handle the stream table that has a list of ids in 'tagged_ids' or the 'message_tags' that is a List<List<tagObject>>

message_tags (class java.util.ArrayList): [[{id=100002886616615, name=Robert Blair, type=user, offset=0, length=12}]]

Should I make a bug, or make a pull request. (not the git expert yet, mind you.)

habuma, don't go rushing to add this stuff quite yet -
I've found another facet in the facebook world.
Some of the FQL values in json can come as a sparse array OR regular array
eg,
"message_tags": { "7": [ {
"id": 157167397630682,
"name": "INQ Mobile (SF)",
"type": "page",
"offset": 7,
"length": 15
}]},
or
message_tage[[{"offset":0, ...}]]

Might add a getSparseArray(fieldName, Mapper()) function that handles that.
It's a bit confusing, so I'll need to think if there is a better way, or one that does not require a library change.
