Interface PropertiesInjector

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

DefaultPropertiesInjector, FilteredPropertiesInjector

public interface PropertiesInjector
extends java.io.Serializable

Represents the logic that pulls property values from a Dependency object and inject them into the appropriate properties.

A typical implementation may use java.beans package to do introspection. Yet, it is also possible to use any other naming convention, such as "injectAge" for property "age", or use the "age" field directly.
