An operation, triggered by a key on the calculator keyboard, or executed as part of a program.

Constructors

arg → Arg: A description of this arguments operation, or ArgDone if there is none. For example, the STO operation has an argument to indicate which register to store to.
read-onlyoverride
argShift → ProgramOperation?: If used as an argument, the shift key needed for that argument. Rare: sto g and rcl g do this.
read-onlyinherited
debugLogId ↔ int: latefinalinherited
endsDigitEntry → bool: read-only
hashCode → int: The hash code for this object.
read-onlyinherited
isShift → bool: Is this the f or g shift key?
read-onlyinherited
maxOneByteOpcodes → int: read-onlyinherited
name → String: Human-readable name for program listing
final
numericValue → int?: Give the numeric value of a number key, or one of the 15C's letters (which are 20..24). cf. tests.dart, SelfTests.testNumbers().
read-onlyinherited
programListingArgName → String?: Name for this key as an arg in the program listing, if other than the default.
read-onlyinherited
rcName ↔ String: The row/column "name", which for digits looks like " 1".
latefinalinherited
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited

beforeCalculate(Resting resting) → void
calcDisabled(Controller controller) → bool: By default, operations, if present, work for all kinds of controllers, but cf. BranchingOperation
makeInputState(Arg arg, Controller c, LimitedState fromState) → ControllerState
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.
inherited
possiblyAlterStackLift(Controller c) → void: Either enable or disable stack lift, if appropriate, after this operation's calculation is done. This will not be called if this operation doesn't have a calculation (intCalc or floatCalc on itself, or on its argument).
pressed(LimitedState arg) → void: What to do when the key is pressed.
toString() → String: A string representation of this object.
