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 include -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.

Member Function Documentation

◆ getFnWhnTrnOffVdd()

fncPtrType VdblMPBttn::getFnWhnTrnOffVdd ( )

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

◆ getFrcOtptLvldWhnVdd()

bool VdblMPBttn::getFrcOtptLvldWhnVdd ( )

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 stOnWhnOtptFrcd attribute.

If the frcOtptLvlWhnVdd attribute flag is set to true, the instantiated object will force the isOn flag attribute value when entering the voided state, in which case the enforced value will be defined by the stOnWhnOtptFrcd (Set On When Output Forced) attribute. If this attribute value is true, the isOn attribute flag will be forced to true, if it is false the isOn attribute flag will be forced to false. In both cases, if the isOn value is forced to change, the respective turning on or turning off actions will be executed.

Returns: the current value of the stOnWhnOtptFrcd 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.

◆ setFnWhnTrnOnVddtPtr()

void VdblMPBttn::setFnWhnTrnOnVddtPtr ( 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
