Constructor Detail

ModelUtils

protected ModelUtils(Elements elementUtils,
                     Types typeUtils)

Parameters:

elementUtils - The Elements

typeUtils - The Types

Method Detail

getTypeUtils

public Types getTypeUtils()

Returns:

The type utilities

classElementFor

@Nullable
public final TypeElement classElementFor(Element element)

Obtains the TypeElement for an given element.

Parameters:

element - The element

Returns:

The TypeElement

concreteConstructorFor

@Nullable
public ExecutableElement concreteConstructorFor(TypeElement classElement,
                                                          AnnotationUtils annotationUtils)

The constructor inject for the given class element.

Parameters:

classElement - The class element

annotationUtils - The annotation utilities

Returns:

The constructor

hasDefaultConstructor

public boolean hasDefaultConstructor(TypeElement classElement)

Parameters:

classElement - The class element

Returns:

True if the element has a non private 0 arg constructor

resolveKind

public 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

resolveKind

public 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
