Method Details

getDeclaringClass

Class<?> getDeclaringClass()

getName

String getName()

getType

Class<?> getType()

getGenericType

Type getGenericType()

As defined by Method.getGenericReturnType() and Field.getGenericType().

Returns:

never null

executeGetter

Object executeGetter(Object bean)

getGetterFunction

<Fact_,
Result_> Function<Fact_,Result_> getGetterFunction()

In order to support node sharing in constraint streams, we need to reference executeGetter(Object) in a way so that the method reference stays the same instance. This method returns just such a method reference.

Type Parameters:

Result_ -

Returns:

never null, a constant reference to executeGetter(Object)

supportSetter

boolean supportSetter()

executeSetter

void executeSetter(Object bean,
 Object value)

getSpeedNote

String getSpeedNote()

getAnnotation

<T extends Annotation> T getAnnotation(Class<T> annotationClass)

As defined in AnnotatedElement.getAnnotation(Class).

getDeclaredAnnotationsByType

<T extends Annotation> T[] getDeclaredAnnotationsByType(Class<T> annotationClass)
