## Member Function Documentation

## ◆ add_device()

void InputDeviceManager::add_device | ( | InputDevice * | device | ) |

Called when a new device has been discovered.

This may also be used to register virtual devices.

This causes a connect-device event to be thrown.

Definition at line 91 of file inputDeviceManager.cxx.

References InputDeviceSet::add_device().

## ◆ get_devices() [1/2]

InputDeviceSet InputDeviceManager::get_devices | ( |  | ) | const

Description: Returns all currently connected devices.

Definition at line 53 of file inputDeviceManager.cxx.

## ◆ get_devices() [2/2]

InputDeviceSet InputDeviceManager::get_devices | ( | InputDevice::DeviceClass | device_class | ) | const

Description: Returns all currently connected devices of the given device class.

Definition at line 69 of file inputDeviceManager.cxx.

## ◆ get_global_ptr()

InputDeviceManager * InputDeviceManager::get_global_ptr | ( |  | ) |
| inline static

Returns the singleton InputDeviceManager instance.

Definition at line 17 of file inputDeviceManager.I.

## ◆ remove_device()

void InputDeviceManager::remove_device | ( | InputDevice * | device | ) |

Called when a device has been removed, or when a device should otherwise no longer be tracked.

This causes a disconnect-device event to be thrown.

Definition at line 112 of file inputDeviceManager.cxx.

## ◆ update()

void InputDeviceManager::update | ( |  | ) |
| virtual

Polls the system to see if there are any new devices.

In some implementations this is a no-op.
