Detailed Description

Singleton class tracking all opened Device objects from drivers.

This affects all devices loaded via the native ImgLib.LoadImageFileW method.

Member Function Documentation

Add()

bool Add

(

Device

device

)

Adds a device to the global driver set.

Parameters

device

Device to add to the set.

Returns

true if device was not present and thus could be added; false if it was present and could not be added.

Implements IDeviceSet.

Contains()

bool Contains	(	Device	deviceToCheck,
		out Device	presentDevice
	)

Checks whether an instance equivalent to deviceToCheck is present in this set.

Parameters

deviceToCheck	Device to be checked whether an equivalent device is available in this set.
presentDevice	Contains the equivalent device which is present in this set if available; null otherwise.

Returns

true if equivalent device is present; false if not.

Implements IDeviceSet.

GetDevices()

IEnumerable< Device > GetDevices

(

)

Gets all currently tracked devices.

Returns

All currently tracked devices, alive or not.

Implements IDeviceSet.

RaiseAdded()

void RaiseAdded ( Device  device )

protected

Raises the Added event.

Parameters

device

Device which is added.

RaiseRemoved()

void RaiseRemoved ( Device  device )

protected

Raises the Removed event.

Parameters

device

Removed device.

Remove()

bool Remove

(

Device

device

)

Removes the given device from the global driver set.

Parameters

device

Device to remove.

Returns

true if device was present and thus could be removed; false if it was not present.

Implements IDeviceSet.

Event Documentation

Removed

EventHandler<DeviceEventArgs> Removed

Occurs when a device is removed.

Beware of using the associated object as it is either disposed or in the process of disposing.
