String.

Contents

A lightweight non-templated alternative to std::string with support for custom deleters. A non-owning version of this container is a StringView.

Usage

It's recommended to prefer using StringView in most cases, and only create a String instance if you need to extend lifetime of the data or mutate it. The String is implicitly convertible from C string literals, but the designated way to instantiate a string is using the operator""_s() literal. While both expressions are mostly equivalent, the implicit conversion has some runtime impact due to std::strlen(), and it won't preserve zero bytes inside the string:

Containers::String a = "hello\0world!";         // a.size() == 5
Containers::String b = "hello\0world!"_s;       // a.size() == 12

String instances are implicitly convertible from and to (mutable) StringView, all instances (including an empty string) are guaranteed to be null-terminated, which means a conversion to StringView will always have StringViewFlag::NullTerminated set.

As with StringView, the class is implicitly convertible to ArrayView. In addition it's also move-convertible to Array, transferring the ownership of the internal data array to it. Ownership transfer in the other direction is not provided because it's not possible to implicitly guarantee null termination of the input Array — use the explicit String(char*, std::size_t, Deleter) constructor together with Array::release() in that case.

Small string optimization

The class stores data size, data pointer and a deleter pointer, which is 24 bytes on 64-bit platforms (and 12 bytes on 32-bit). To avoid allocations for small strings, small strings up to 22 bytes on 64-bit (23 including the null terminator) and up to 10 bytes on 32-bit (11 including the null terminator) are by default stored inside the class.

Such optimization is completely transparent to the user, the only difference is that deleter() and release() can't be called on SSO strings, as there is nothing to delete / release. Presence of SSO on an instance can be queried using isSmall(). In cases where SSO isn't desired (for example when storing pointers to string contents stored in a growable array), the string can be constructed using the AllocatedInit tag (for example with String(AllocatedInitT, const char*)), which bypasses this optimization and always allocates.

String initialization

In addition to creating a String from an existing string (literal) or wrapping an externally allocated memory as mentioned above, explicit initialization constructors are provided, similarly to the Array class:

  • String(ValueInitT, std::size_t) zero-initializes the string, meaning each of its characters is '\0'. For heap-allocated strings this is equivalent to new char[size + 1]{} (the one extra character is for the null terminator).
  • String(DirectInitT, std::size_t, char) fills the whole string with given character and zero-initializes the null terminator. For heap-allocated strings this is equivalent to new char[size + 1]{c, c, c, …, '\0'}.
  • String(NoInitT, std::size_t) keeps the contents uninitialized, except for the null terminator. Equivalent to new char[size + 1] followed by string[size] = '\0'.

STL compatibility

Instances of String are implicitly convertible from and to std::string if you include Corrade/Containers/StringStl.h. The conversion is provided in a separate header to avoid unconditional #include <string>, which significantly affects compile times. The following table lists allowed conversions:

Corrade type↭STL type
String⇆std::string

Example:

std::string a = "Hello world!";
Containers::String b = a.substr(5);

Because std::string doesn't provide any way to transfer ownership of its underlying memory, conversion either way always involves an allocation and a copy. To mitigate the conversion impact, it's recommended to convert std::string instances to StringView instead where possible.

Function documentation

static String Corrade::Containers::String::nullTerminatedView(StringView view)

Turn a view into a null-terminated string.

If the view is StringViewFlag::NullTerminated, returns a non-owning reference to it without any extra allocations or copies involved. Otherwise allocates a null-terminated owning copy using String(StringView).

This function is primarily meant for efficiently passing StringView instances to APIs that expect null-terminated const char*. Mutating the result in any way is undefined behavior.

static String Corrade::Containers::String::nullTerminatedGlobalView(StringView view)

Turn a view into a null-terminated global string.

If the view is both StringViewFlag::NullTerminated and StringViewFlag::Global, returns a non-owning reference to it without any extra allocations or copies involved. Otherwise allocates a null-terminated owning copy using String(StringView).

This function is primarily meant for efficiently storing StringView instances, ensuring the memory stays in scope and then passing them to APIs that expect null-terminated const char*. Mutating the result in any way is undefined behavior.

Corrade::Containers::String::String() noexcept

Default constructor.

Creates an empty string.

Corrade::Containers::String::String(StringView view)

Construct from a string view.

Creates a null-terminated owning copy of view. Contrary to the behavior of std::string, view is allowed to be nullptr, but only if it's size is zero. Depending on the size, it's either stored allocated or in a SSO.

Corrade::Containers::String::String(Containers::ArrayView<const char> view)

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

Corrade::Containers::String::String(MutableStringView view)

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

Corrade::Containers::String::String(Containers::ArrayView<char> view)

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

Corrade::Containers::String::String(const char* data)

Construct from a null-terminated C string.

Creates a null-terminated owning copy of data. Contrary to the behavior of std::string, data is allowed to be nullptr — in that case an empty string is constructed. Depending on the size, it's either stored allocated or in a SSO.

Corrade::Containers::String::String(const char* data, std::size_t size)

Construct from a sized C string.

Creates a null-terminated owning copy of data. Contrary to the behavior of std::string, data is allowed to be nullptr, but only if size is zero. Depending on the size, it's either stored allocated or in a SSO.

Corrade::Containers::String::String(AllocatedInitT, StringView view) explicit

Construct from a string view, bypassing SSO.

Compared to String(StringView) the data is always allocated.

Corrade::Containers::String::String(AllocatedInitT, Containers::ArrayView<const char> view) explicit

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

Construct from a null-terminated C string, bypassing SSO.

Compared to String(const char*) the data is always allocated.

Corrade::Containers::String::String(AllocatedInitT, const char* data, std::size_t size) explicit

Construct from a sized C string.

Compared to String(const char*, std::size_t) the data is always allocated.

Corrade::Containers::String::String(char* data, std::size_t size, Deleter deleter) explicit noexcept

Take ownership of an external data array.

Parameters
data String
size Size of the string, excluding the null terminator
deleter Deleter. Use nullptr for the standard delete[].

Since the String class provides a guarantee of null-terminated strings, the data array is expected to be null-terminated (which implies data can't be nullptr), but the null terminator not being included in size. For consistency and interoperability with Array this in turn means the size passed to deleter is one byte less than the actual memory size, and if the deleter does sized deallocation, it has to account for that.

Corrade::Containers::String::String(const char* data, std::size_t size, Deleter deleter) explicit noexcept

Take ownership of an immutable external data array.

Casts away the const and delegates to String(char*, std::size_t, Deleter). This constructor is provided mainly to allow a String instance to reference global immutable data (such as C string literals) without having to allocate a copy, it's the user responsibility to avoid mutating the data in any way.

Corrade::Containers::String::String(std::nullptr_t, std::size_t size, Deleter deleter) explicit deleted

Taking ownership of a null pointer is not allowed.

Since the String class provides a guarantee of null-terminated strings, data can't be nullptr.

Corrade::Containers::String::String(ValueInitT, std::size_t size) explicit

Create a zero-initialized string of given size.

Parameters
size Size excluding the null terminator

A DefaultInitT overload isn't provided to prevent accidents — its behavior would be the same to String(NoInitT, std::size_t).

Corrade::Containers::String::String(DirectInitT, std::size_t size, char c) explicit

Create a string initialized to a particular character.

Parameters
size Size excluding the null terminator
c Character value

Corrade::Containers::String::String(NoInitT, std::size_t size) explicit

Create an uninitialized string.

Parameters
size Size excluding the null terminator

While the string contents are left untouched, the null terminator does get initialized to '\0'. Useful if you're going to overwrite the contents anyway.

template<class T, class = decltype(Implementation::StringConverter<typename std::decay<T && >::type>::from(std::declval<T && >()))>
Corrade::Containers::String::String(T&& other) noexcept

Construct a view on an external type / from an external representation.

Corrade::Containers::String::~String()

Destructor.

Calls deleter() on the owned data(); in case of a SSO does nothing.

Corrade::Containers::String::operator ArrayView<const char>() const noexcept

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

bool Corrade::Containers::String::contains(StringView substring) const

Whether the view contains a substring.

Equivalent to BasicStringView::contains().

char* Corrade::Containers::String::release()

Release data storage.

Returns the data pointer and resets data pointer, size and deleter to be equivalent to a default-constructed instance. Can be called only if the string is not stored using SSO — see Small string optimization for more information. Deleting the returned array is user responsibility — note the string might have a custom deleter() and so delete[] might not be always appropriate.
