Examples of GroupIterator

client.net.sf.saxon.ce.expr.sort.GroupIterator
A GroupIterator is an iterator that iterates over a sequence of groups. The normal methods such as next() and current() always deliver the leading item of the group. Additional methods are available to get the grouping key for the current group (only applicable to group-by and group-adjacent), and to get all the members of the current group.

org.apache.camel.util.GroupIterator
Group based {@link Iterator} which groups the given {@link Iterator} a number of timesand then return a combined response as a String.
This implementation uses as internal byte array buffer, to combine the response. The token is inserted between the individual parts.
For example if you group by new line, then a new line token is inserted between the lines.
