Class BeansOfTypeDependency<T>

java.lang.Object

rocks.frieler.android.beans.BeansOfTypeDependency<T>

Type Parameters:

T - the bean-type

All Implemented Interfaces:

BeanDependency<java.util.List<T>>

public class BeansOfTypeDependency<T>
extends java.lang.Object
implements BeanDependency<java.util.List<T>>

BeanDependency to express a dependency on the beans of a certain type.

Be aware that this dependency cannot guarantee to provide all beans of that type, because the exact runtime type of a bean and whether it is a subtype of the desired type cannot be determined before the bean's construction. Hence this dependency always indicates to be unfulfilled, but optional. It will gather as many beans as possible by obtaining the beans as late as possible.
