Methods

buttonDown(Operation key) → void
Handle an operation due to a press on the keyboard.
inherited
buttonUp() → void
Finish the operation started by buttonDown. This is meaningful for some keys, like SST, show-hex and clear-prefix.
override
buttonWidgetDown(CalculatorButton b) → void
inherited
delayForShow(int updateDisplay()) → bool
override
getArgsAndRun(Operation op, Arg arg, Resting fromState) → void
Get the arguments described by Arg, and then run it.
override
getErrorNumber(CalculatorError err) → int
override
handlePSE() → void
Handle the pause operation. Note that this enables stack lift -- see p. 100
override
newSelfTests({bool inCalculator = true}) → SelfTests
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
pasteToX(String clipboard) → bool
inherited
reset() → void
Reset everything but the state of the state machine
inherited
resetAll() → void
inherited
returnToParent(ControllerState s) → void
setArg(ArgDone argValue) → void
showCalculatorError(CalculatorError e, StackTrace? stack) → void
Show an error on the LCD screen.
override
showMessage(String message) → void
Show a message on the LCD screen.
inherited
singleStep(DigitEntry? digitEntryStateFrom) → void
Perform a single step action by running one instruction, and then returning to an appropriate state (DigitEntry or Running, as determined by the executed instruction).
override
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
