      owner - the internal name of the method's owner class (see Type.getInternalName()).
      name - the method's name.
      descriptor - the method's descriptor (see Type).
      isInterface - if the method's owner class is an interface.

    • invokeinterface

      public void invokeinterface(String owner, String name, String descriptor)
      Generates the instruction to call the given interface method.
      Parameters:
      owner - the internal name of the method's owner class (see Type.getInternalName()).
      name - the method's name.
      descriptor - the method's descriptor (see Type).

    • invokedynamic

      public void invokedynamic(String name, String descriptor, org.objectweb.asm.Handle bootstrapMethodHandle, Object[] bootstrapMethodArguments)
      Generates the instruction to call the given dynamic method.
      Parameters:
      name - the method's name.
      descriptor - the method's descriptor (see Type).
      bootstrapMethodHandle - the bootstrap method.
      bootstrapMethodArguments - the bootstrap method constant arguments. Each argument must be an Integer, Float, Long, Double, String, Type, Handle or ConstantDynamic value. This method is allowed to modify the content of the array so a caller should expect that this array may change.
