Modifier and Type	Method and Description
static <A extends Annotation> Class<?>	getAnnotatedMethodClass(javax.interceptor.InvocationContext context, Class<A> annotationClass) Returns either the CDI Proxy class (for cases where a class extends another without overriding the target method), or the actual declaring class if the annotation isn't present on the proxy class.

Method Detail

getAnnotation

public static <A extends Annotation> A getAnnotation(Stereotypes sterotypes,
                                                     Class<A> annotationClass,
                                                     javax.interceptor.InvocationContext context)

Gets the annotation from the method that triggered the interceptor.

Type Parameters:

A - The annotation type to return

Parameters:

sterotypes - The invoking interceptor's context on sterotype annotations

annotationClass - The class of the annotation to get

context - The context of the method invocation

Returns:

The annotation that triggered the interceptor.

getOverrideValue

public static <A extends Annotation,T> T getOverrideValue(org.eclipse.microprofile.config.Config config,
                                                          Class<A> annotationType,
                                                          String parameterName,
                                                          javax.interceptor.InvocationContext context,
                                                          Class<T> parameterType,
                                                          T defaultValue)

Gets overriding config parameter values if they're present from an invocation context.

Type Parameters:

A - The annotation type

Parameters:

config - The config to get the overriding parameter values from

annotationType - The annotation class

parameterName - The name of the parameter to get the override value of

context - The context of the invoking request

parameterType - The type of the parameter to get the override value of

Returns:

getEnabledOverrideValue

public static <A extends Annotation> boolean getEnabledOverrideValue(org.eclipse.microprofile.config.Config config,
                                                                     Class<A> annotationType,
                                                                     javax.interceptor.InvocationContext context,
                                                                     boolean defaultValue)

Gets overriding config enabled parameter value if it's present from an invocation context. This follows a different priority logic than other parameter overrides.

Type Parameters:

A - The annotation type

Parameters:

config - The config to get the overriding enabled value from

annotationType - The annotation class

context - The context of the invoking request

Returns:

getAnnotatedMethodClass

public static <A extends Annotation> Class<?> getAnnotatedMethodClass(javax.interceptor.InvocationContext context,
                                                                      Class<A> annotationClass)

Returns either the CDI Proxy class (for cases where a class extends another without overriding the target method), or the actual declaring class if the annotation isn't present on the proxy class.

Type Parameters:

A - The class of the annotation

Parameters:

context - The context of the method invocation

annotationClass - The class of the annotation

Returns:

The class of the annotated method

getPlainCanonicalName

public static <A extends Annotation> String getPlainCanonicalName(Class<?> type)

Helper method that gets the canonical name of an annotated class. This is used to strip out any Weld proxy naming that gets appended to the real class name.

Type Parameters:

A - The class of the annotation

Parameters:

type - The class of the annotation

Returns:

The canonical name of the annotated method's class

getCanonicalMethodName

public static String getCanonicalMethodName(javax.interceptor.InvocationContext context)

Gets the full method signature from an invocation context, stripping out any Weld proxy name gubbins.

Parameters:

context - The context of the method invocation

Returns:

full canonical name of the method as in my.pack.MyClass.myMethod

isAnnotatedWithFaultToleranceAnnotations

public static boolean isAnnotatedWithFaultToleranceAnnotations(javax.enterprise.inject.spi.Annotated element)

toClassArray

public static <T> Class<? extends T>[] toClassArray(String classNames,
                                                    String attributeName,
                                                    Class<? extends T>[] defaultValue)
