## 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).

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 | ( |  | ) |

|  | const String & | defaultValue
| ) |  |
| static

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

## ◆ getFullUserName()
