static

Returns the host-name of the computer.

◆ getCpuModel()

String juce::SystemStats::getCpuModel ( )
static

Attempts to return a string describing the CPU model. May not be available on some systems.

◆ getCpuSpeedInMegahertz()

int juce::SystemStats::getCpuSpeedInMegahertz ( )
static

Returns the approximate CPU speed.

Returns
the speed in megahertz, e.g. 1500, 2500, 32000 (depending on what year you're reading this...)

◆ getCpuSpeedInMegaherz()

int juce::SystemStats::getCpuSpeedInMegaherz ( )
inlinestatic

◆ getCpuVendor()

String juce::SystemStats::getCpuVendor ( )
static

Returns a string to indicate the CPU vendor. Might not be known on some systems.

◆ getDeviceDescription()

String juce::SystemStats::getDeviceDescription ( )
static

This will attempt to return some kind of string describing the device. If no description is available, it'll just return an empty string. You may want to use this for things like determining the type of phone/iPad, etc.

◆ getDeviceIdentifiers()

StringArray juce::SystemStats::getDeviceIdentifiers ( )
static

This method calculates some IDs to uniquely identify the device.

The first choice for an ID is a filesystem ID for the user's home folder or windows directory. If that fails then this function returns the MAC addresses.

◆ getDeviceManufacturer()

String juce::SystemStats::getDeviceManufacturer ( )
static

This will attempt to return the manufacturer of the device. If no description is available, it'll just return an empty string.

◆ getDisplayLanguage()

String juce::SystemStats::getDisplayLanguage ( )
static

Returns the user's display language. The return value is a 2 or 3 letter language code (ISO 639-1 or ISO 639-2). Note that depending on the OS and region, this may also be followed by a dash and a sub-region code, e.g "en-GB"

◆ getEnvironmentVariable()

String juce::SystemStats::getEnvironmentVariable ( const String & name,
const String & defaultValue )
static

Returns an environment variable. If the named value isn't set, this will return the defaultValue string instead.

◆ getFullUserName()

String juce::SystemStats::getFullUserName ( )
static

Returns the current user's full name, if available. On some OSes, this may just return the same value as getLogonName().

See also
getLogonName()

◆ getJUCEVersion()

String juce::SystemStats::getJUCEVersion ( )
static

Returns the current version of JUCE, See also the JUCE_VERSION, JUCE_MAJOR_VERSION and JUCE_MINOR_VERSION macros.

◆ getLogonName()

String juce::SystemStats::getLogonName ( )
static

Returns the current user's name, if available.

See also
getFullUserName()

◆ getMemorySizeInMegabytes()

int juce::SystemStats::getMemorySizeInMegabytes ( )
static

Finds out how much RAM is in the machine.

Returns
the approximate number of megabytes of memory, or zero if something goes wrong when finding out.

◆ getNumCpus()

staticnoexcept

Returns the number of logical CPU cores.

◆ getNumPhysicalCpus()

int juce::SystemStats::getNumPhysicalCpus ( )

String juce::SystemStats::getOperatingSystemName ( )
static

Returns the name of the type of operating system we're running on.

Returns
a string describing the OS type.
See also
getOperatingSystemType

◆ getOperatingSystemType()

SystemStats::OperatingSystemType juce::SystemStats::getOperatingSystemType ( )
static

Returns the type of operating system we're running on.

Returns
one of the values from the OperatingSystemType enum.
See also
getOperatingSystemName

static

Returns the system page-size. This is only used by programmers with beards.

◆ getStackBacktrace()

String juce::SystemStats::getStackBacktrace ( )
static

Returns a backtrace of the current call-stack. The usefulness of the result will depend on the level of debug symbols that are available in the executable.

◆ getUserLanguage()
