Annotation Type ParametersSuppliedBy

@Retention(value=RUNTIME)
@Target(value={ANNOTATION_TYPE,PARAMETER})
public @interface ParametersSuppliedBy

Annotating a Theory method parameter with @ParametersSuppliedBy causes it to be supplied with values from the named ParameterSupplier when run as a theory by the Theories runner. In addition, annotations themselves can be annotated with @ParametersSuppliedBy, and then used similarly. ParameterSuppliedBy annotations on parameters are detected by searching up this hierarchy such that these act as syntactic sugar, making:

 @ParametersSuppliedBy(Supplier.class)
 public @interface SpecialParameter { }
 
 @Theory
 public void theoryMethod(@SpecialParameter String param) {
   ...
 }
 

equivalent to:

 @Theory
 public void theoryMethod(@ParametersSuppliedBy(Supplier.class) String param) {
   ...
 }
