## Member Enumeration Documentation

## ◆ OperatingSystemType

enum juce::SystemStats::OperatingSystemType

The set of possible results of the getOperatingSystemType() method.

Enumerator
MacOSX | To test whether any version of OSX is running, you can use the expression ((getOperatingSystemType() & MacOSX) != 0).
Windows | To test whether any version of Windows is running, you can use the expression ((getOperatingSystemType() & Windows) != 0).

| static

Returns the host-name of the computer.

## ◆ getCpuModel()

static String juce::SystemStats::getCpuModel | ( |  | ) |

| static

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

## ◆ getDeviceDescription()

static 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 | ( |  | ) |

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()

static 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()
