类 CandidateComponentsIndex

java.lang.Object
cn.taketoday.context.loader.CandidateComponentsIndex
public class CandidateComponentsIndex extends Object
Provide access to the candidates that are defined in META-INF/today.components.

An arbitrary number of stereotypes can be registered (and queried) on the index: a typical example is the fully qualified name of an annotation that flags the class for a certain use case. The following call returns all the @Component candidate types for the com.example package (and its sub-packages): 

 Set<String> candidates = index.getCandidateTypes(
         "com.example", "cn.taketoday.stereotype.Component");

The type is usually the fully qualified name of a class, though this is not a rule. Similarly, the stereotype is usually the fully qualified name of a target type but it can be any marker really.
