RclIndirectArg class Null safety

This is where the HP 15C shows its evil genius. RCL (i), when I contains a number, immediately recalls the register whose number is given in I (converted to an integer), so it behaves like ArgDone.

When I contains a matrix descriptor, it behaves like a matrix: It shows the matrix row/column, with a timeout, and only completes the recall operation if the button is released before the timeout expires. So, when I contains a matrix descriptor, it behaves like DeferredRclArg, above.

And they did all this in a tiny, power-efficient form factor with a 4 bit processor, and (I assume) pushing the limits of their small ROM capacity.

Methods

getCalculation<T extends ProgramOperation>(Model<ProgramOperation> m, DisplayModeSelector<(void Function(Model<ProgramOperation>)?), T> selector) → (void Function(Model<ProgramOperation>)?)
inherited
handleOpBeforeCalculate(Model<ProgramOperation> m, void opBeforeCalculate()) → void
For many of the RCL operations on matrices, we need to take over stack lift, so we do the deferral on beforeCalculate rather than calc.
override
init(int registerBase, {required OpInitFunction f, required ProgramOperation? shift, required bool argDot, required ProgramOperation? arg, required bool userMode}) → void
inherited
liftStackIfEnabled(Model<ProgramOperation> m) → bool
inherited
matches(ProgramOperation key, bool userMode) → Arg?
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.

toString() → String
A string representation of this object.
