Constructor & Destructor Documentation

CommandParameterWordPtr() [1/2]

Burger::CommandParameterWordPtr::CommandParameterWordPtr ( const char * pHelp, const char ** ppParameterName, uintptr_t uParameterCount, uintptr_t uDefault, uintptr_t uMin = 0, uintptr_t uMax = UINTPTR_MAX )

inlinenoexcept

Constructor for multiple valid commands.

---

In cases there multiple commands can trigger this command, pass a pointer to an array of "C" strings and the array size in entries to construct this parameter parser

Note

Do not set the count to 0, it will cause this class to treat the array pointer as a direct pointer which may not be desired behavior

Parameters

pHelp	Pointer to "C" string for usage
ppParameterName	Pointer to an array of "C" strings for valid inputs
uParameterCount	Number of entries in the array (1-XX).
uDefault	Default value to return if no parameter was parsed
uMin	Minimum allowable value
uMax	Maximum allowable value

CommandParameterWordPtr() [2/2]

Burger::CommandParameterWordPtr::CommandParameterWordPtr ( const char * pHelp, const char * pParameterName, uintptr_t uDefault, uintptr_t uMin = 0, uintptr_t uMax = UINTPTR_MAX )

inlinenoexcept

Constructor for a single valid command.

---

The default value is set to uDefault.

Parameters

pHelp	Pointer to "C" string for usage.
pParameterName	Pointer to a "C" string to match to trigger this parameter.
uDefault	Default value to return if no parameter was parsed
uMin	Minimum allowable value
uMax	Maximum allowable value

Member Function Documentation

Action()

int Burger::CommandParameterWordPtr::Action ( int argc, const char ** argv )

overridevirtual

Parses a numeric string.

---

If there is a parameter in the list, parse it as a numeric string. Test against the valid range and return either -1 if an error occurred or 2 to remove the 2 command entries.

Parameters

argc	Number of parameters in argv.
argv	Array of "C" strings.

Returns

Returns -1 on error or 2 for success

Implements Burger::CommandParameter.

GetValue()

uintptr_t Burger::CommandParameterWordPtr::GetValue ( void ) const

inlinenoexcept

Returns the value.

---

Returns the contained value

Returns

Returns the parsed value
