Java
'Map' can be replaced with 'EnumMap'
Warning
New
Last modified: 03 December 2024 Reports instantiations of java.util.Map
objects whose key types are enumerated classes. Such java.util.Map
objects can be replaced with java.util.EnumMap
objects.
java.util.EnumMap
implementations can be much more efficient because the underlying data structure is a simple array.
Example:
Map<MyEnum, String> myEnums = new HashMap<>();
After the quick-fix is applied:
Map<MyEnum, String> myEnums = new EnumMap<>(MyEnum.class);
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
