A tag that takes an iterator and outputs a subset of it. It delegates to
+ SubsetIteratorFilter internally to
+ perform the subset functionality.
+
+
+
+
+
count (Object) - Indicate the number of entries to be in the resulting subset iterator
+
source* (Object) - Indicate the source of which the resulting subset iterator is to be derived base on
+
start (Object) - Indicate the starting index (eg. first entry is 0) of entries in the source to be available as the first entry in the resulting subset iterator
+
decider (Object) - Extension to plug-in a decider to determine if that particular entry is to be included in the resulting subset iterator
+
id (String) - Indicate the pageContext attribute id to store the resultant subset iterator in
+
