This library contains utility classes used by all other Corrade parts, like debug and error output (class Debug), access to configuration files (class Configuration) or compiling data files into the executable (class Resource, see also tutorial).

This library is built if WITH_UTILITY is enabled when building Corrade. To use this library with CMake, you need to request the Utility component of the Corrade package and link to the Corrade::Utility target:

find_package(Corrade REQUIRED Utility)

# ...
target_link_libraries(your-app Corrade::Utility)

See also Downloading and building Corrade and Using Corrade with CMake for more information.

Enums

enum class ConfigurationValueFlag: std::uint8_t { Oct = 1 << 0, Hex = 1 << 1, Scientific = 1 << 2, Uppercase = 1 << 3 }: Configuration value conversion flag.

Typedefs

using ConfigurationValueFlags = Containers::EnumSet<ConfigurationValueFlag>: Configuration value conversion flags.
template<class T> using IsIterable = std::integral_constant<bool,(Implementation::HasMemberBegin<T>::value||Implementation::HasBegin<T>::value||Implementation::HasStdBegin<T>::value)&&(Implementation::HasMemberEnd<T>::value||Implementation::HasEnd<T>::value||Implementation::HasStdEnd<T>::value)>: Traits class for checking whether given type is iterable.

Functions

auto operator<<(Debug& debug, Debug::Color value) -> Debug&: Debug output operator.
void sleep(std::size_t ms) deprecated: Sleep for given time.

Type utilities

template<class To, class From> auto bitCast(const From& from) -> To: Cast type to another of the same size.

Enum documentation

enum class Corrade::Utility::ConfigurationValueFlag: std::uint8_t

Configuration value conversion flag.

Enumerators
Oct	Numeric value as octal
Hex	Numeric value as hexadecimal
Scientific	Floating point values in scientific notation
Uppercase	Use uppercase characters for numeric output

Typedef documentation

typedef Containers::EnumSet<ConfigurationValueFlag> Corrade::Utility::ConfigurationValueFlags

Configuration value conversion flags.

template<class T>
using Corrade::Utility::IsIterable = std::integral_constant<bool,(Implementation::HasMemberBegin<T>::value||Implementation::HasBegin<T>::value||Implementation::HasStdBegin<T>::value)&&(Implementation::HasMemberEnd<T>::value||Implementation::HasEnd<T>::value||Implementation::HasStdEnd<T>::value)>

Traits class for checking whether given type is iterable.

Equivalent to std::true_type if the class is has either begin() / end() members, is usable with free begin() / end() functions or has std::begin() / std::end() overloads. Otherwise equivalent to std::false_type.

Function documentation

Debug& Corrade::Utility::operator<<(Debug& debug, Debug::Color value)

Debug output operator.

void Corrade::Utility::sleep(std::size_t ms)

Sleep for given time.

template<class To, class From>
To Corrade::Utility::bitCast(const From& from)

Cast type to another of the same size.

Unlike reinterpret_cast this doesn't break strict-aliasing rules.
