Method Detail

create

public static AnnotatedMethod create(Method method)

Create an AnnotatedMethod instance from a Java method.

Parameters:

method - the Java method

Returns:

an AnnotatedMethod instance representing the Java method

Throws:

NullPointerException - if the method parameter is null

method

public Method method()

Get the underlying Java method.

This will be the method that is actually annotated with GrpcMethod, which may be the same as or overridden by the method returned by declaredMethod().

Returns:

the actual annotated Java method.

declaredMethod

public Method declaredMethod()

Get the declared Java method.

This method overrides, or is the same as, the one retrieved by method().

Returns:

the declared Java method.

parameterAnnotations

public Annotation[][] parameterAnnotations()

Get method parameter annotations.

Returns:

method parameter annotations.

parameterTypes

public Class<?>[] parameterTypes()

Get method parameter types. See also Method.getParameterTypes().

Returns:

method parameter types.

typeParameters

public TypeVariable<Method>[] typeParameters()

Get method type parameters. See also Method.getTypeParameters().

Returns:

method type parameters.

genericParameterTypes

public Type[] genericParameterTypes()

Get generic method parameter types. See also Method.getGenericParameterTypes().

Returns:

generic method parameter types.

genericReturnType

public Type genericReturnType()

Get generic method return type. See also Method.getGenericReturnType() ()}.

Returns:

generic method return types.

returnType

public Class<?> returnType()

Get method return type. See also Method.getReturnType() ()} ()}.

Returns:

method return types.

metaMethodAnnotations

public <T extends Annotation> Stream<T> metaMethodAnnotations(Class<T> annotation)

Get all instances of the specified meta-annotation type found on the method annotations (a meta-annotation is an annotation that annotates other annotations).

Type Parameters:

T - meta-annotation type.

Parameters:

annotation - meta-annotation class to be searched for.

Returns:

meta-annotation instances of a given type annotating the method annotations.

firstAnnotationOrMetaAnnotation

public <T extends Annotation> T firstAnnotationOrMetaAnnotation(Class<T> type)

Get the first of the specified meta-annotation type found on the method annotations or on the method itself (a meta-annotation is an annotation that annotates other annotations).

Type Parameters:

T - meta-annotation type.

Parameters:

type - meta-annotation class to be searched for.

Returns:

meta-annotation instances of a given type annotating the method annotations

annotationOrMetaAnnotation

public <T extends Annotation> Stream<T> annotationOrMetaAnnotation(Class<T> type)

Get all instances of the specified meta-annotation type found on the method annotations or on the method itself (a meta-annotation is an annotation that annotates other annotations).

Type Parameters:

T - meta-annotation type.

Parameters:

type - meta-annotation class to be searched for.

Returns:

meta-annotation instances of a given type annotating the method annotations

annotationsWithMetaAnnotation

public Stream<Annotation> annotationsWithMetaAnnotation(Class<? extends Annotation> type)

Get all instances of annotations annotated with the specified meta-annotation.

Parameters:

type - meta-annotation class to be searched for.

Returns:

all instances of annotations annotated with the specified meta-annotation
