public class MapEntryOrKeyValue
extends ClosureSignatureHint

A special hint which handles a common use case in the Groovy methods that work on maps. In case of an iteration on a list of map entries, you often want the user to be able to work either on a Entry map entry or on a key,value pair.

The result is a closure which can have the following forms:

• { key, value -> ... } where key is the key of a map entry, and value the corresponding value
• { entry -> ... } where entry is a Entry map entry
• { ... } where it is an implicit Entry map entry

This hint handles all those cases by picking the generics from the first argument of the method (by default).

The options array is used to modify the behavior of this hint. Each string in the option array consists of a key=value pair.

• argNum=index of the parameter representing the map (by default, 0)
• index=true or false, by default false. If true, then an additional "int" parameter is added, for "withIndex" variants
