getThrows

public List<Class<?>> getThrows()

Void is considered a declared return.

Returns:

canThrow

canReturn

public boolean canReturn(Class<?> type)

filterPayloadArgs

public List<?> filterPayloadArgs(Set<Class<? extends Annotation>> annotations)

findOnDeclaringClass

public <A extends Annotation,
V> Optional<A> findOnDeclaringClass(Class<A> annotationClass)

Find all arguments of the given parameter type.

Type Parameters:

R - Parameter type

Parameters:

type - Class of the parameter type

Returns:
