Method Detail

resolveKind

public static Optional<ElementKind> resolveKind(Element element)

The Java APT throws an internal exception {code com.sun.tools.javac.code.Symbol$CompletionFailure} if a class is missing from the classpath and Element.getKind() is called. This method handles exceptions when calling the getKind() method to avoid this scenario and should be used instead of Element.getKind().

Parameters:

element - The element

Returns:

The kind if it is resolvable

resolveKind

public static Optional<ElementKind> resolveKind(Element element,
                                                ElementKind expected)

The Java APT throws an internal exception {code com.sun.tools.javac.code.Symbol$CompletionFailure} if a class is missing from the classpath and Element.getKind() is called. This method handles exceptions when calling the getKind() method to avoid this scenario and should be used instead of Element.getKind().

Parameters:

element - The element

expected - The expected kind

Returns:

The kind if it is resolvable and matches the expected kind

isInterface

public static boolean isInterface(Element element)

Whether the given element is an interface.

Parameters:

element - The element

Returns:

True if it is

isClass

public static boolean isClass(Element element)

Whether the given element is a class.

Parameters:

element - The element

Returns:

True if it is

isEnum

public static boolean isEnum(Element element)

Whether the given element is an enum.

Parameters:

element - The element

Returns:

True if it is

isClassOrInterface

public static boolean isClassOrInterface(Element element)

Whether the given element is a class or interface.

Parameters:

element - The element

Returns:

True if it is

getClassName

public static String getClassName(TypeElement typeElement)

Get the class name for the given type element. Handles NestingKind.

Parameters:

typeElement - The type element

Returns:

The class name
