ConstructorInvocation
public ConstructorInvocation(
@NonNull Class<Object> clazz,
@Nullable Class<Annotation> annotationClass,
@Nullable Class[] parameterTypes
)
Creates a new ConstructorInvocation.
Constructor lookup is either done using an annotation by passing the annotationClass as a parameter or through parameterTypes lookup. This class will attempt to lookup a constructor by first looking for a constructor annotated with annotationClass. If no constructors are found it will fallback and try to use parameterTypes.
| Parameters | |
|---|---|
@NonNull Class<Object> clazz |
the declared class to create the instance off |
@Nullable Class<Annotation> annotationClass |
the annotation class to lookup the constructor |
@Nullable Class[] parameterTypes |
array of parameter types to lookup a constructor on the declared class. The declared order of parameter types must match the order of the constructor parameters passed into |
