Description
Component for MergeIteratorTag, which job is to merge iterators and successive call to the merged iterator will cause each merge iterator to have a chance to expose its element, subsequently next call will allow the next iterator to expose its element. Once the last iterator is done exposing its element, the first iterator is allowed to do so again (unless it is exhausted of entries).
Internally the task are delegated to MergeIteratorFilter
Example if there are 3 lists being merged, each list have 3 entries, the following will be the logic.
- Display first element of the first list
- Display first element of the second list
- Display first element of the third list
- Display second element of the first list
- Display second element of the second list
- Display second element of the third list
- Display third element of the first list
- Display thrid element of the second list
- Display third element of the thrid list
