Detailed Description🔗

class iox::cxx::convert;

Collection of static methods for conversion from and to string. 

std::string number      = cxx::convert::toString(123);
std::string someClass   = cxx::convert::toString(someToStringConvertableObject);

int i;
unsigned int a;
if ( cxx::convert::fromString("123", i) ) {}  // will succeed
if ( cxx::convert::fromString("-123", a) ) {} // will fail since -123 is not unsigned

function toString🔗

template <typename Source >
static inline std::enable_if<!std::is_convertible< Source, std::string >::value, std::string >::type toString(
    const Source & t
)

Converts every type which is either a pod (plain old data) type or is convertable to a string (this means that the operator std::string() is defined)

Parameters:

  • Source type of the value which should be converted to a string
  • t value which should be converted to a string

Return: string representation of t

function toString🔗

template <typename Source >
static std::enable_if< std::is_convertible< Source, std::string >::value, std::string >::type toString(
    const Source & t
)

Converts every type which is either a pod (plain old data) type or is convertable to a string (this means that the operator std::string() is defined)

Parameters:

  • Source type of the value which should be converted to a string
  • t value which should be converted to a string

Return: string representation of t

function fromString🔗

template <typename Destination >
static bool fromString(
    const char * v,
    Destination & dest
)

Sets dest from a given string. If the conversion fails false is returned and the value of dest is undefined.

Parameters:

  • v string which contains the value of dest
  • dest destination to which the value should be written

Return: false = if the conversion fails otherwise true

function stringIsNumber🔗

static inline bool stringIsNumber(
    const char * v,
    const NumberType type
)

checks if a given string v is a number

Parameters:

  • v string which contains the number
  • type is the expected contained type in v

Return: true if the given string is a number, otherwise false
