## Detailed Description

Abstract class, base to model Voidable DD-MPBs (VDD-MPB).

Voidable DD-MPBs are MPBs whose distinctive characteristic is that implement non-latching switches that while being pressed their state might change from On State to a Voided state due to different voiding conditions. Depending on the classes the voided state might be Voided & Off state, Voided & On state or Voided & Not enforced states. Those conditions to change to a voided state include -but are not limited to- the following conditions:

- pressing time
- external signals
- entering the On state

The mechanisms to "un-void" the MPB and return it to an operational state includes -but are not limited to- the following actions:

- releasing the MPBs
- receiving an external signal
- the reading of the isOn attribute flag status

The voiding conditions and the un-voiding mechanisms define the VDD-MPB subclasses.

## Constructor & Destructor Documentation

## ◆ VdblMPBttn()

VdblMPBttn::VdblMPBttn | ( | const uint8_t & | mpbttnPin,
|  | const bool & | pulledUp = true,
|  | const bool & | typeNO = true,
|  | const unsigned long int & | dbncTimeOrigSett = 0,
|  | const unsigned long int & | strtDelay = 0,
|  | const bool & | isOnDisabled = false )

Class constructor.

Parameters

  isOnDisabled | (Optional) Sets the instantiation value for the isOnDisabled flag attribute.

Note
  For the other parameters see DbncdDlydMPBttn(GPIO_TypeDef*, const uint16_t, const bool, const bool, const unsigned long int, const unsigned long int)

## Member Function Documentation

## ◆ getFnWhnTrnOffVdd()

fncPtrType VdblMPBttn::getFnWhnTrnOffVdd | ( |  | ) |

Returns the function that is set to execute every time the object exits the Voided State.

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

Returns
  A function pointer to the function set to execute every time the object enters the Unvoided or "Voieded Off" State.

Return values

  nullptr | if there is no function set to execute when the object enters the Unvoided (or "Voided Off") State.

## ◆ getFnWhnTrnOnVdd()

fncPtrType VdblMPBttn::getFnWhnTrnOnVdd | ( |  | ) |

Returns the function that is set to execute every time the object enters the Voided or "Voided On" State.

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

Returns
  A function pointer to the function set to execute every time the object enters the Voided (or "Voided On") State.

Return values

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

## ◆ getFrcOtptLvlWhnVdd()

bool VdblMPBttn::getFrcOtptLvlWhnVdd | ( |  | ) |

Returns the value of the frcOtptLvlWhnVdd attribute.

The frcOtptLvlWhnVdd (Force Output Level When Voided) attribute configures the object to either keep it's isOn attribute flag current value when entering the voided state (false) or to force it to a specific isOn value (true).

Returns
  the current value of the frcOtptLvlWhnVdd attribute.

Note
  As of this version of the library no VdblMPBttn class or subclasses make use of the frcOtptLvlWhnVdd attribute, their inclusion is "New Features Under Development" related to the refactoring of binary states to Non-binary states.

## ◆ getIsVoided()

const bool VdblMPBttn::getIsVoided | ( |  | ) | const

Returns the current value of the isVoided attribute flag.

Returns
  The value of the flag.

Return values

  true | The object is in voided state
  false | The object is in not voided state

## ◆ getStOnWhnOtpFrcd()

bool VdblMPBttn::getStOnWhnOtpFrcd | ( |  | ) |

Returns the value of the frcOtptLvlWhnVdd attribute.

The frcOtptLvlWhnVdd (Force Output Level When Voided) attribute configures the object to either keep it's isOn attribute flag current value when entering the voided state (false) or to force it to a specific isOn value (true).

If the object is set to force to a specific isOn value (true), the forced value to be set will be determined by the stOnWhnOtptFrcd attribute.

Returns
  the current value of the frcOtptLvlWhnVdd attribute.

Note
  As of this version of the library no VdblMPBttn class or subclasses make use of the frcOtptLvlWhnVdd attribute, their inclusion is "New Features Under Development" related to the refactoring of binary states to Non-binary states.

## ◆ setFnWhnTrnOffVddPtr()

void VdblMPBttn::setFnWhnTrnOffVddPtr | ( | void(* | newFnWhnTrnOff )() | ) |

Sets the function that will be called to execute every time the object's isVoided attribute flag is reset.

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's isVoided attribute flag is reset. Passing nullptr as parameter deactivates the function execution mechanism.

## ◆ setFnWhnTrnOnVddPtr()

void VdblMPBttn::setFnWhnTrnOnVddPtr | ( | void(* | newFnWhnTrnOn )() | ) |

Sets the function that will be called to execute every time the object's isVoided attribute flag is set.

The function to be executed must be of the form void (*newFnWhnTrnOn)(), 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's isVoided is set. Passing nullptr as parameter deactivates the function execution mechanism.

## ◆ setIsNotVoided()

bool VdblMPBttn::setIsNotVoided | ( |  | ) |

Sets the value of the isVoided attribute flag to false.

Warning
  The value of the isVoided attribute flag is computed as a result of the current state of the instantiated object, considering the inputs and embedded simulated behavior.
  - Arbitrarily setting a value to the isVoided attribute flag might affect the normal behavior path for the object.
  - The attribute flag value might return to it's natural value when the behavior imposes the change.
  - The use of this method must be limited to certain states and conditions of the object, being the most suitable situation while the object is in Disabled state: If the application development requires the isVoided attribute flag to be in a specific value, this method and the setIsVoided() method are the required tools.

Return values

  true |

Here is the caller graph for this function:

## ◆ setIsVoided()

bool VdblMPBttn::setIsVoided | ( |  | ) |

Sets the value of the isVoided attribute flag to true.

Warning
  See the Warnings for setIsNotVoided()

Return values

  true |
