Class Maps

java.lang.Object

com.github.andrewoma.dexx.collection.Maps

public class Maps
extends java.lang.Object

Maps is the preferred method of constructing instances of Map.

HashMap is currently constructed in all cases, however this may change in the future.

Maps is preferred for construction as:

• It works better in languages that support type inference
• It allows future optimisations (e.g. small maps may be dedicated classes which are then upgraded to HashMaps)
