Method Details

scanProjectForAnnotationAndCastToInterface

public static <T extends Annotation,
K> List<K> scanProjectForAnnotationAndCastToInterface(Class<T> annotationClazz,
 Class<K> castInterface)

Scans the project for classes annotated with a specific annotation and casts them to a given interface.

Type Parameters:

T - the type of the annotation

K - the type of the interface

Parameters:

annotationClazz - the class object representing the annotation to scan for

castInterface - the class object representing the interface to cast the annotated classes to

Returns:

a list of instances of the annotated classes casted to the specified interface

scanClassImplInterface

public static <T> List<T> scanClassImplInterface(Class<T> castInterface,
 String packagePath)

Scans the classpath for classes implementing a specific interface.

Type Parameters:

T - the type of the interface

Parameters:

castInterface - the class object representing the interface to scan for implementations

packagePath - the package path to scan for classes

Returns:

a list of instances of the classes implementing the specified interface

deduceMainApplicationClass

public static Class<?> deduceMainApplicationClass()

Deduces the main application class by inspecting the stack trace.

Returns:

the main application class, or null if it cannot be deduced
