Annotation Type DataPoint

    @Retention(value=RUNTIME)
    @Target(value={FIELD,METHOD})
    public @interface DataPoint

Annotating an field or method with @DataPoint will cause the field value or the value returned by the method to be used as a potential parameter for theories in that class, when run with the `Theories` runner.

A DataPoint is only considered as a potential value for parameters for which its type is assignable. When multiple `DataPoint`s exist with overlapping types more control can be obtained by naming each DataPoint using the value of this annotation, e.g. with `@DataPoint({"dataset1", "dataset2"})`, and then specifying which named set to consider as potential values for each parameter using the `@FromDataPoints` annotation.

Parameters with no specified source (i.e. without @FromDataPoints or other `@ParameterSuppliedBy` annotations) will use all `DataPoint`s that are assignable to the parameter type as potential values, including named sets of `DataPoint`s.

     @DataPoint
     public static String dataPoint = "value";

     @DataPoint("generated")
     public static String generatedDataPoint() {
         return "generated value";
     }

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