Method Detail

getParameter

public java.lang.reflect.Parameter getParameter()

Description copied from interface: ParameterContext

Get the Parameter for this context.

WARNING

When searching for annotations on the parameter in this context, favor ParameterContext.isAnnotated(Class), ParameterContext.findAnnotation(Class), and ParameterContext.findRepeatableAnnotations(Class) over methods in the Parameter API due to a bug in javac on JDK versions prior to JDK 9.

Specified by:

getParameter in interface ParameterContext

Returns:

the parameter; never null

See Also:

ParameterContext.getIndex()

getIndex

public int getIndex()

Description copied from interface: ParameterContext

Get the index of the Parameter for this context within the parameter list of the Executable that declares the parameter.

Specified by:

getIndex in interface ParameterContext

Returns:

the index of the parameter

See Also:

ParameterContext.getParameter(), Executable.getParameters()

getTarget

public java.util.Optional<java.lang.Object> getTarget()

Description copied from interface: ParameterContext

Get the target on which the Executable that declares the Parameter for this context will be invoked, if available.

Specified by:

getTarget in interface ParameterContext

Returns:

an Optional containing the target on which the Executable will be invoked; never null but will be empty if the Executable is a constructor or a static method.

isAnnotated

public boolean isAnnotated(java.lang.Class<? extends java.lang.annotation.Annotation> annotationType)

Description copied from interface: ParameterContext

Determine if an annotation of annotationType is either present or meta-present on the AnnotatedElement for this context.

WARNING

Favor the use of this method over directly invoking AnnotatedElement.isAnnotationPresent(Class) due to a bug in javac on JDK versions prior to JDK 9.

Specified by:

isAnnotated in interface AnnotatedElementContext

Specified by:

isAnnotated in interface ParameterContext

Parameters:

annotationType - the annotation type to search for; never null

Returns:

true if the annotation is present or meta-present

See Also:

AnnotatedElementContext.findAnnotation(Class), AnnotatedElementContext.findRepeatableAnnotations(Class)

findAnnotation

public <A extends java.lang.annotation.Annotation> java.util.Optional<A> findAnnotation(java.lang.Class<A> annotationType)

Description copied from interface: ParameterContext

Find the first annotation of annotationType that is either present or meta-present on the AnnotatedElement for this context.

WARNING

Favor the use of this method over directly invoking annotation lookup methods in the AnnotatedElement API due to a bug in javac on JDK versions prior to JDK 9.

Specified by:

findAnnotation in interface AnnotatedElementContext

Specified by:

findAnnotation in interface ParameterContext

Type Parameters:

A - the annotation type

Parameters:

annotationType - the annotation type to search for; never null

Returns:

an Optional containing the annotation; never null but potentially empty

See Also:

AnnotatedElementContext.isAnnotated(Class), AnnotatedElementContext.findRepeatableAnnotations(Class)

findRepeatableAnnotations

public <A extends java.lang.annotation.Annotation> java.util.List<A> findRepeatableAnnotations(java.lang.Class<A> annotationType)

Description copied from interface: ParameterContext

Find all repeatable annotations of annotationType that are either present or meta-present on the AnnotatedElement for this context.

WARNING

Favor the use of this method over directly invoking annotation lookup methods in the AnnotatedElement API due to a bug in javac on JDK versions prior to JDK 9.

Specified by:

findRepeatableAnnotations in interface AnnotatedElementContext

Specified by:

findRepeatableAnnotations in interface ParameterContext

Type Parameters:

A - the annotation type

Parameters:

annotationType - the repeatable annotation type to search for; never null

Returns:

the list of all such annotations found; neither null nor mutable, but potentially empty

AnnotatedElementContext.isAnnotated(Class), AnnotatedElementContext.findAnnotation(Class), Repeatable
