    • isPrimitive

      public static boolean isPrimitive(@NonNull @NonNull org.objectweb.asm.Type type)
      Checks if passed type is a primitive.
      Parameters:
      type - type to check
      Returns:
      true if it is

    • isBoolean

      public static boolean isBoolean(@NonNull @NonNull org.objectweb.asm.Type type)
      Checks if passed type is either boolean primitive or wrapper.
      Parameters:
      type - type to check
      Returns:
      true if it is

    • isNumeric

      @NonNull public static @io.micronaut.core.annotation.NonNull boolean isNumeric(@NonNull @NonNull org.objectweb.asm.Type type)
      Checks if passed type is one of numeric primitives or numeric wrappers.
      Parameters:
      type - type to check
      Returns:
      true if it is

    • 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
