    • unboxIfRequired

      public static void unboxIfRequired(org.objectweb.asm.MethodVisitor mv, org.jboss.jandex.Type jandexType)
      Calls the right unboxing method for the given Jandex Type if it is a primitive.
      Parameters:
      mv - The MethodVisitor on which to visit the unboxing instructions
      jandexType - The Jandex Type to unbox if it is a primitive.

    • unboxIfRequired

      public static void unboxIfRequired(org.objectweb.asm.MethodVisitor mv, org.objectweb.asm.Type type)
      Calls the right unboxing method for the given Jandex Type if it is a primitive.
      Parameters:
      mv - The MethodVisitor on which to visit the unboxing instructions
      type - The Jandex Type to unbox if it is a primitive.

    • getLoadOpcode

      public static int getLoadOpcode(org.jboss.jandex.Type jandexType)
      Returns the bytecode instruction to load the given Jandex Type. This returns the specialised bytecodes ILOAD, DLOAD, FLOAD and LLOAD for primitives, or ALOAD otherwise.
      Parameters:
      jandexType - The Jandex Type whose load instruction to return.
      Returns:
      The bytecode instruction to load the given Jandex Type.

    • getStoreOpcode

      public static int getStoreOpcode(org.jboss.jandex.Type jandexType)
      Returns the bytecode instruction to store the given Jandex Type. This returns the specialised bytecodes ISTORE, DSTORE, FSTORE and LSTORE for primitives, or ASTORE otherwise.
      Parameters:
      jandexType - The Jandex Type whose store instruction to return.
      Returns:
      The bytecode instruction to store the given Jandex Type.

    • getNullValueOpcode

      public static int getNullValueOpcode(org.jboss.jandex.Type jandexType)
      Returns a null value suitable for initialising variables to null or its equivalent for primitives

    • getParameterSize

      public static int getParameterSize(org.jboss.jandex.Type paramType)
      Returns the number of underlying bytecode parameters taken by the given Jandex parameter Type. This will be 2 for doubles and longs, 1 otherwise.
      Parameters:
      paramType - the Jandex parameter Type
      Returns:
      the number of underlying bytecode parameters required.
