Method Detail

getParameterAnnotation

public static <T extends java.lang.annotation.Annotation> T getParameterAnnotation(java.lang.reflect.Method method,
                                                                                   int i,
                                                                                   java.lang.Class<T> annotationType)

Returns an annotation of the ith parameter; or null if none.

getParameterAnnotationWithName

public static java.lang.annotation.Annotation getParameterAnnotationWithName(java.lang.reflect.Method method,
                                                                             int i,
                                                                             java.lang.String annotationName,
                                                                             @Nullable

Returns an annotation with the given name from the ith parameter; or null if none.

Parameters:

method - The method which will have its parameters searched for the annotation.

i - The index specifying which parameter to search on the given method.

annotationName - Fully qualified name of the java class for the target annotation type.

valueType - If non-null, an annotation will only be considered a match if it has a property "value" with the given type.

getNamedParameter

public static java.lang.annotation.Annotation getNamedParameter(java.lang.reflect.Method method,
                                                                int i,
                                                                java.lang.Class<? extends java.lang.annotation.Annotation> internalNamedType)

Returns the @Named annotation of the ith parameter. Prefers the given internal type, but if not present, returns the javax @Named.

Parameters:

method - The method which will have its parameters searched for the annotation.

i - The index specifying which parameter to search on the given method.

internalNamedType - The type to use for the SPI-owned version of @Named.

getNullableParameter

public static java.lang.annotation.Annotation getNullableParameter(java.lang.reflect.Method method,
                                                                   int i,

Returns the @Nullable annotation of the ith parameter. Prefers the given internal type, but if not present, returns the javax @Nullable.

Parameters:

method - The method which will have its parameters searched for the annotation.

i - The index specifying which parameter to search on the given method.

internalNullableType - The type to use for the SPI-owned version of @Nullable.
