------------------------------------
Assignee: Julian Hyde
> Add class PairList
> ------------------
>
> Key: CALCITE-5706
> URL: https://issues.apache.org/jira/browse/CALCITE-5706
> Project: Calcite
> Issue Type: Bug
> Reporter: Julian Hyde
> Assignee: Julian Hyde
> Priority: Major
>
> Add a {{class PairList}} which an implementation of {{List<Map.Entry<K, V>}}
> backed by a single list. It can be used to build two lists in parallel (e.g.
> a list of field types and field names that will be converted to a struct
> type); it can also be used to build maps.
> It has a {{forEach(BiConsumer<K, V>)}} method to allow the list to be
> deconstructed without creating intermediate entries.
> Potentially also {{toImmutableMap}} and {{toHashMap}} methods.
