containerBeforeContainee

back to summary

private static <A extends Annotation> boolean containerBeforeContainee(Map<Class<? extends Annotation>, Annotation> annotations, Class<A> annoClass)

Figures out if container class comes before containee class among the keys of the given map.

Returns:boolean: true if container class is found before containee class when iterating over annotations.keySet().

getAssociatedAnnotations back to summary

getAssociatedAnnotations	back to summary
public static <A extends Annotation> A[] getAssociatedAnnotations(Map<Class<? extends Annotation>, Annotation> declaredAnnotations, Class<?> decl, Class<A> annoClass) Finds and returns all associated annotations matching the given class. The order of the elements in the array returned depends on the iteration order of the provided maps. Specifically, the directly present annotations come before the indirectly present annotations if and only if the directly present annotations come before the indirectly present annotations in the relevant map. Parameters declaredAnnotations:Map<Class<? extends Annotation>, Annotation> the declared annotations indexed by their types decl:Class<?> the class declaration on which to search for annotations annoClass:Class<A> the type of annotation to search for Returns:A[] an array of instances of `annoClass` or an empty array if none were found.

public static <A extends Annotation> A[] getAssociatedAnnotations(Map<Class<? extends Annotation>, Annotation> declaredAnnotations, Class<?> decl, Class<A> annoClass)

Finds and returns all associated annotations matching the given class. The order of the elements in the array returned depends on the iteration order of the provided maps. Specifically, the directly present annotations come before the indirectly present annotations if and only if the directly present annotations come before the indirectly present annotations in the relevant map.

Parameters

declaredAnnotations:Map<Class<? extends Annotation>, Annotation>: the declared annotations indexed by their types
decl:Class<?>: the class declaration on which to search for annotations
annoClass:Class<A>: the type of annotation to search for

Returns:A[]

an array of instances of annoClass or an empty array if none were found.

getDirectlyAndIndirectlyPresent back to summary

getDirectlyAndIndirectlyPresent	back to summary
public static <A extends Annotation> A[] getDirectlyAndIndirectlyPresent(Map<Class<? extends Annotation>, Annotation> annotations, Class<A> annoClass) Finds and returns all annotations in `annotations` matching the given `annoClass`. Apart from annotations directly present in `annotations` this method searches for annotations inside containers i.e. indirectly present annotations. The order of the elements in the array returned depends on the iteration order of the provided map. Specifically, the directly present annotations come before the indirectly present annotations if and only if the directly present annotations come before the indirectly present annotations in the map. Parameters annotations:Map<Class<? extends Annotation>, Annotation> the `Map` in which to search for annotations annoClass:Class<A> the type of annotation to search for Returns:A[] an array of instances of `annoClass` or an empty array if none were found

public static <A extends Annotation> A[] getDirectlyAndIndirectlyPresent(Map<Class<? extends Annotation>, Annotation> annotations, Class<A> annoClass)

Finds and returns all annotations in annotations matching the given annoClass. Apart from annotations directly present in annotations this method searches for annotations inside containers i.e. indirectly present annotations. The order of the elements in the array returned depends on the iteration order of the provided map. Specifically, the directly present annotations come before the indirectly present annotations if and only if the directly present annotations come before the indirectly present annotations in the map.

Parameters

annotations:Map<Class<? extends Annotation>, Annotation>: the Map in which to search for annotations
annoClass:Class<A>: the type of annotation to search for

Returns:A[]

an array of instances of annoClass or an empty array if none were found

getIndirectlyPresent back to summary

getIndirectlyPresent	back to summary
private static <A extends Annotation> A[] getIndirectlyPresent(Map<Class<? extends Annotation>, Annotation> annotations, Class<A> annoClass) Finds and returns all annotations matching the given `annoClass` indirectly present in `annotations`. Parameters annotations:Map<Class<? extends Annotation>, Annotation> annotations to search indexed by their types annoClass:Class<A> the type of annotation to search for Returns:A[] an array of instances of `annoClass` or an empty array if no indirectly present annotations were found

private static <A extends Annotation> A[] getIndirectlyPresent(Map<Class<? extends Annotation>, Annotation> annotations, Class<A> annoClass)

Finds and returns all annotations matching the given annoClass indirectly present in annotations.

Parameters

annotations:Map<Class<? extends Annotation>, Annotation>: annotations to search indexed by their types
annoClass:Class<A>: the type of annotation to search for

Returns:A[]

an array of instances of annoClass or an empty array if no indirectly present annotations were found
