@ThreadSafe
public final class ConfigurationPropertiesResolveContext
     
     

      
      extends

      implements 
      
      ResolveContext
     
     

Simple interface on ConfigurationProperties.

Implementation Notes:

the implementation is thread safe since it only provides read access to the wrapped configuration. If the configuration is accessed by other threads, it is not.
