Method Summary

Modifier and Type	Method and Description
static Class	findConfiguredClass(Class<?> testClass) Finds the first class in a class hierarchy that is annotated with ArtifactClassLoaderRunnerConfig.
static <T> T	getAnnotationAttributeFrom(Class<?> klass, Class<? extends Annotation> annotationClass, String methodName) Looks for the Annotation in the Class and invokes the Method.
static <T> List<T>	getAnnotationAttributeFromHierarchy(Class<?> klass, Class<? extends Annotation> annotationClass, String methodName) Looks for the Annotation in the Class and invokes the Method in the whole hierarhcy until it reaches Object.

Method Detail

getAnnotationAttributeFrom

public static <T> T getAnnotationAttributeFrom(Class<?> klass,
                                               Class<? extends Annotation> annotationClass,
                                               String methodName)

Looks for the Annotation in the Class and invokes the Method. It will return the result of the invocation. If there Class is not annotated it will return the default value from the Annotation.

Type Parameters:

T - the result of the invocation

Parameters:

klass - the Class where to look for the annotation

annotationClass - the Annotation class to look for

methodName - the method name of the annotation to be called

Returns:

the attribute from the annotation for the given class

Throws:

IllegalStateException - if the method is not defined in the annotation

getAnnotationAttributeFromHierarchy

public static <T> List<T> getAnnotationAttributeFromHierarchy(Class<?> klass,
                                                              Class<? extends Annotation> annotationClass,
                                                              String methodName)

Looks for the Annotation in the Class and invokes the Method in the whole hierarhcy until it reaches Object. It will return a List with the results of each invocation. If there Class is not annotated it will return the default value from the Annotation.

Type Parameters:

T - the result of the invocation

Parameters:

klass - the Class where to look for the annotation

annotationClass - the Annotation class to look for

methodName - the method name of the annotation to be called

Returns:

a (@link List} of T for the attributes annotated in all the object hierarchy until it reaches Object class.

Throws:

IllegalStateException - if the method is not defined in the annotation

findConfiguredClass

public static Class findConfiguredClass(Class<?> testClass)

Finds the first class in a class hierarchy that is annotated with ArtifactClassLoaderRunnerConfig.

Annotated class is searched by levels, in a Breadth-first search (BFS) way. Starting from the class received as a parameter, first the class is checked and return if annotated. Otherwise interface directly implemented by the class will be added to review and finally its super class.

Implemented interfaces have priority over class hierarchy as base classes can be imported from other modules with different runner configurations.

Parameters:

testClass - class of the test begin executed by the test runner.

Returns:

the first class found in the hierarchy that is annotated, null if no class in the hierarchy is annotated.
