## Detailed Description

Abstract class, base to model Double Action LDD-MPBs (DALDD-MPBs).

Double Action Latched DD-MPB are MPBs whose distinctive characteristic is that implement switches that present different behaviors based on the time length of the presses detected and the sequence of the presses. The pattern selected for this class is the following:

- A short press makes the MPB to behave as a Toggle LDD-MPB Switch (ToLDD-MPB) -designated as the main behavior-, swapping from the Off state to the On state and back as usual LDD-MPB.
- A long press activates another behavior, allowing the only MPB to be used as a second MPB. That different behavior -designated as the secondary behavior- defines the sub-classes of the DALDD-MPB class. Using a notation where the first component is the Off/On state of the main behavior and the second component the state of the secondary behavior the only possible combinations would be:
- 1. Off-Off
- 2. On-Off
- 3. On-On

The presses patterns are:

- 1. -> 2.: short press.
- 1. -> 3.: long press.
- 2. -> 3.: long press.
- 2. -> 1.: short press.
- 3. -> 2.: secondary behavior unlatch (subclass dependent, maybe release, external unlatch, etc.)

Note
  The short press will always be calculated as the Debounce + Delay set attributes.
  The long press is a configurable attribute of the class, the Secondary Mode Activation Delay (scndModActvDly) that holds the time after the Debounce + Delay period that the MPB must remain pressed to activate the mentioned mode. The same time will be required to keep pressed the MPB while in Main Behavior to enter the Secondary behavior.

## Member Function Documentation

## ◆ getFnWhnTrnOffScndry()

fncPtrType DblActnLtchMPBttn::getFnWhnTrnOffScndry | ( |  | ) |

returns the function that is set to execute every time the object enters the Secondary Off State.

The function to be executed is an attribute that might be modified by the setFnWhnTrnOffScndryPtr() method.

Returns
  A function pointer to the function set to execute every time the object enters the Secondary Off State.

Return values

  nullptr | if there is no function set to execute when the object enters the Secondary Off State.

## ◆ getFnWhnTrnOnScndry()

fncPtrType DblActnLtchMPBttn::getFnWhnTrnOnScndry | ( |  | ) |

Returns the function that is set to execute every time the object enters the Secondary On State.

The function to be executed is an attribute that might be modified by the setFnWhnTrnOnScndryPtr() method.

Returns
  A function pointer to the function set to execute every time the object enters the Secondary On State.

Return values

  nullptr | if there is no function set to execute when the object enters the Secondary On State.

## ◆ getIsOnScndry()

bool DblActnLtchMPBttn::getIsOnScndry | ( |  | ) |

Returns the current value of the isOnScndry attribute flag.

The isOnScndry attribute flag holds the secondary On state, when the MPB is pressed for the seted long press time from the Off-Off or the On-Off state as described in the DblActnLtchMPBttn class.

Returns
  The current value of the isOnScndry flag.

## ◆ getScndModActvDly()

unsigned long DblActnLtchMPBttn::getScndModActvDly | ( |  | ) |

Returns the current value of the scndModActvDly class attribute.

The scndModActvDly attribute defines the time length a MPB must remain pressed to consider it a long press, needed to activate the secondary mode.

Returns
  The current scndModActvDly value, i.e. the delay in milliseconds.

## ◆ setFnWhnTrnOffScndryPtr()

void DblActnLtchMPBttn::setFnWhnTrnOffScndryPtr | ( | void(* | newFnWhnTrnOff )() | ) |

Sets the function that will be called to execute every time the object enters the Secondary Off State.

The function to be executed must be of the form void (*newFnWhnTrnOff)(), meaning it must take no arguments and must return no value, it will be executed only once by the object (recursion must be handled with the usual precautions). When instantiated the attribute value is set to nullptr.

Parameters

  newFnWhnTrnOff | Function pointer to the function intended to be called when the object enters the Secondary Off State. Passing nullptr as parameter deactivates the function execution mechanism.

## ◆ setFnWhnTrnOnScndryPtr()

void DblActnLtchMPBttn::setFnWhnTrnOnScndryPtr | ( | void(* | newFnWhnTrnOn )() | ) |

Sets the function that will be called to execute every time the object enters the Secondary On State.

The function to be executed must be of the form void (*newFnWhnTrnOff)(), meaning it must take no arguments and must return no value, it will be executed only once by the object (recursion must be handled with the usual precautions). When instantiated the attribute value is set to nullptr.

Parameters

  newFnWhnTrnOn | function pointer to the function intended to be called when the object enters the Secondary On State. Passing nullptr as parameter deactivates the function execution mechanism.

## ◆ setScndModActvDly()

bool DblActnLtchMPBttn::setScndModActvDly | ( | const unsigned long & | newVal | ) |

Sets a new value for the scndModActvDly class attribute.

The scndModActvDly attribute defines the time length a MPB must remain pressed after the end of the debounce&delay period to consider it a long press, needed to activate the secondary mode. The value setting must be newVal >= _MinSrvcTime to ensure correct signal processing. See TmLtchMPBttn::setSrvcTime(const unsigned long int) for details.

Parameters

  newVal | The new value for the scndModActvDly attribute.

Return values

  true | The new value is in the valid range, the value was updated.
  false | The new value is not in the valid range, the value was not updated.
