  • Method Details

    • 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

    • toUnboxedIfNecessary

      @NonNull public static @NonNull org.objectweb.asm.Type toUnboxedIfNecessary(@NonNull @NonNull org.objectweb.asm.Type type)
      If passed type is boxed type, returns responsive primitive, otherwise returns original passed type.
      Parameters:
      type - type to check
      Returns:
      unboxed type or original passed type

    • toBoxedIfNecessary

      @NonNull public static @NonNull org.objectweb.asm.Type toBoxedIfNecessary(@NonNull @NonNull org.objectweb.asm.Type type)
