Detailed Description

The QLatin1String class provides a thin wrapper around an US-ASCII/Latin-1 encoded string literal.

\inmodule QtCore

\reentrant

Many of QString's member functions are overloaded to accept {const char *} instead of QString. This includes the copy constructor, the assignment operator, the comparison operators, and various other functions such as \l{QString::insert()}{insert()}, \l{QString::replace()}{replace()}, and \l{QString::indexOf()}{indexOf()}. These functions are usually optimized to avoid constructing a QString object for the {const char *} data. For example, assuming str is a QString,

is much faster than

because it doesn't construct four temporary QString objects and make a deep copy of the character data.

Applications that define \l QT_NO_CAST_FROM_ASCII (as explained in the QString documentation) don't have access to QString's {const char *} API. To provide an efficient way of specifying constant Latin-1 strings, Qt provides the QLatin1String, which is just a very thin wrapper around a {const char *}. Using QLatin1String, the example code above becomes

This is a bit longer to type, but it provides exactly the same benefits as the first version of the code, and is faster than converting the Latin-1 strings using QString::fromLatin1().

Thanks to the QString(QLatin1String) constructor, QLatin1String can be used everywhere a QString is expected. For example:

Note: If the function you're calling with a QLatin1String argument isn't actually overloaded to take QLatin1String, the implicit conversion to QString will trigger a memory allocation, which is usually what you want to avoid by using QLatin1String in the first place. In those cases, using QStringLiteral may be the better option.

Constructor & Destructor Documentation

◆ QLatin1String() [1/6]

QLatin1String::QLatin1String ( )

inlineconstexprnoexcept

Since: 5.6

Constructs a QLatin1String object that stores a nullptr.

Definition at line 86 of file qstring.h.

Here is the caller graph for this function:

◆ QLatin1String() [2/6]

QLatin1String::QLatin1String ( const char * str )

inlineexplicitconstexprnoexcept

Constructs a QLatin1String object that stores str.

The string data is not copied. The caller must be able to guarantee that str will not be deleted or modified as long as the QLatin1String object exists.

See also: latin1()

Definition at line 87 of file qstring.h.

◆ QLatin1String() [3/6]

QLatin1String::QLatin1String	(	const char *	first,
		const char *	last
	)

inlineexplicitconstexpr

Since: 5.10

Constructs a QLatin1String object that stores first with length (last - first).

The range {[first,last)} must remain valid for the lifetime of this Latin-1 string object.

Passing \nullptr as first is safe if last is \nullptr, too, and results in a null Latin-1 string.

The behavior is undefined if last precedes first, first is \nullptr and last is not, or if {last - first > INT_MAX}.

Definition at line 88 of file qstring.h.

◆ QLatin1String() [4/6]

QLatin1String::QLatin1String	(	const char *	str,
		qsizetype	size
	)

inlineexplicitconstexprnoexcept

Constructs a QLatin1String object that stores str with size.

The string data is not copied. The caller must be able to guarantee that str will not be deleted or modified as long as the QLatin1String object exists.

Note: : any null ('\0') bytes in the byte array will be included in this string, which will be converted to Unicode null characters (U+0000) if this string is used by QString. This behavior is different from Qt 5.x.

See also: latin1()

Definition at line 90 of file qstring.h.

◆ QLatin1String() [5/6]

QLatin1String::QLatin1String ( const QByteArray & str )

inlineexplicitnoexcept

Constructs a QLatin1String object that stores str.

The string data is not copied. The caller must be able to guarantee that str will not be deleted or modified as long as the QLatin1String object exists.

See also: latin1()

Definition at line 91 of file qstring.h.

◆ QLatin1String() [6/6]

QLatin1String::QLatin1String ( QByteArrayView str )

inlineexplicitconstexprnoexcept

Since: 6.3

Constructs a QLatin1String object that stores str.

The string data is not copied. The caller must be able to guarantee that the data which str is pointing to will not be deleted or modified as long as the QLatin1String object exists. The size is obtained from str as-is, without checking for a null-terminator.

Note: : any null ('\0') bytes in the byte array will be included in this string, which will be converted to Unicode null characters (U+0000) if this string is used by QString.

Since: 5.14

Returns the index position of the last occurrence of the string-view str, Latin-1 string l1, or character ch, respectively, in this Latin-1 string, searching backward from index position from. Returns -1 if str is not found.

If from is -1, the search starts at the last character; if from is -2, at the next to last character and so on.

If cs is Qt::CaseSensitive (default), the search is case sensitive; otherwise the search is case insensitive.

Note: When searching for a 0-length str or l1, the match at the end of the data is excluded from the search by a negative from, even though {-1} is normally thought of as searching from the end of the string: the match at the end is after the last character, so it is excluded. To include such a final empty match, either give a positive value for from or omit the from parameter entirely.

◆ left()

QLatin1String QLatin1String::left ( qsizetype length ) const

Since: 5.8

If you know that length cannot be out of bounds, use first() instead in new code, because it is faster.

Returns the substring of length length starting at position 0 in this Latin-1 string.

The entire Latin-1 string is returned if length is greater than or equal to size(), or less than zero.

Returns the substring of length length starting at position start in this Latin-1 string.

If you know that start and length cannot be out of bounds, use sliced() instead in new code, because it is faster.

Returns an empty Latin-1 string if start exceeds the length of this Latin-1 string. If there are less than length characters available in this Latin-1 string starting at start, or if length is negative (default), the function returns all characters that are available from start.
