Member Function Documentation

isHexNumber()

bool Qx::String::isHexNumber ( QString hexNum )

static

Returns true if hexNum consists only of numbers and letters A through F (case-insensitive); otherwise returns false.

isOnlyNumbers()

bool Qx::String::isOnlyNumbers ( QString checkStr )

static

Returns true if checkStr consists only of numbers; otherwise returns false.

isValidChecksum()

bool Qx::String::isValidChecksum ( QString checksum, QCryptographicHash::Algorithm hashAlgorithm )

static

Returns true if checksum consists only of valid hexadecimal characters and is the exact length required for a hexadecimal string representation of hashAlgorithm; otherwise returns false.

join() [1/4]

QString Qx::String::join ( QList< QString > list, QString separator = {}, QString prefix = {} )

static

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Joins all the strings in list with an optional separator and prefix for each element into a single string.

See also

QStringList::join().

join() [2/4]

template<typename T , typename F >
requires defines_call_for_s<F, QString, const T&>

QString Qx::String::join ( QList< T > list, F && toStringFunc, QString separator = {}, QString prefix = {} )

inlinestatic

Joins all arbitrarily typed elements from a list into a single string with optional formatting.

Parameters

[in]	list	The list of elements to join
[in]	toStringFunc	A function that takes a single element of type T and returns a QString
[in]	separator	An optional character to place between each element
[in]	prefix	An optional string to place before each element

join() [3/4]

QString Qx::String::join ( QSet< QString > set, QString separator = {}, QString prefix = {} )

static

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Joins all the strings in set with an optional separator and prefix for each element into a single string.

join() [4/4]

template<typename T , typename F >
requires defines_call_for_s<F, QString, const T&>

QString Qx::String::join ( QSet< T > set, F && toStringFunc, QString separator = {}, QString prefix = {} )

inlinestatic

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Joins all arbitrarily typed elements from a set into a single string with optional formatting.

Parameters

[in]	set	The set of elements to join
[in]	toStringFunc	A function that takes a single element of type T and returns a QString
[in]	separator	An optional character to place between each element
[in]	prefix	An optional string to place before each element

stripToHexOnly()

QString Qx::String::stripToHexOnly ( QString string )

static

Returns a copy of string with all non-hexadecimal characters removed.

trimLeading()

QString Qx::String::trimLeading ( const QStringView string )

static

Returns a copy of string with all whitespace at the beginning of the string removed.

Whitespace means any character for which QChar::isSpace() returns true. This includes the ASCII characters \t, \n, \v, \f, \r, and .

Internal whitespace is unaffected.

See also

trimTrailing() and QString::trimmed().

trimTrailing()

QString Qx::String::trimTrailing ( const QStringView string )

static

Returns a copy of string with all whitespace at the end of the string removed.

Whitespace means any character for which QChar::isSpace() returns true. This includes the ASCII characters \t, \n, \v, \f, \r, and .

Internal whitespace is unaffected.

trimLeading() and QString::trimmed().
