@Singleton constructors

Last modified: 03 December 2024

Reports constructors of classes annotated by @Singleton unless it is declared non-strict.

Example:

@Singleton
class Foo{
    Foo(){
    }
}

There are two possible quick-fixes: either to remove the constructor or to declare @Singleton non-strict.

After the quick-fix is applied:

@Singleton
class Foo{
}

or:

@Singleton(strict = false)
class Foo{
    Foo(){
    }
}
