Method Summary

Modifier and Type	Method and Description
default int	getPriority() Dependency sources are called in ascending order based of their priority.

dependency - The class of the dependency to resolve

Returns:

the value resolved for this dependency or null if dependency can't be resolved by this source

getPriority

default int getPriority()

Returns:

the priority for this dependency source

injectRecursively

default boolean injectRecursively()

Indicates if the last returned dependency should have its fields be resolved by the dependency injector or not.
