Detailed Description

Generic interface to deal with a device.

It exposes a set of properties and is organized a a key/value set.

Warning: Using this class could expose some backend specific details and lead to non portable code. Use it at your own risk, or during transitional phases when the provided device interfaces don't provide the necessary methods.

Member Function Documentation

allProperties()

virtual QMap< QString, QVariant > Solid::Ifaces::GenericInterface::allProperties ( ) const

pure virtual

Retrieves all the properties of this device.

Returns

all properties in a map

conditionRaised()

virtual void Solid::Ifaces::GenericInterface::conditionRaised ( const QString & condition, const QString & reason )

protectedpure virtual

This signal is emitted when an event occurred in the device.

For example when a button is pressed.

Parameters

condition	the condition name
reason	a message explaining why the condition has been raised

property()

virtual QVariant Solid::Ifaces::GenericInterface::property ( const QString & key ) const

pure virtual

Retrieves the value of a property.

Parameters

key	the property name

Returns

the property value or QVariant() if the property doesn't exist

propertyChanged()

virtual void Solid::Ifaces::GenericInterface::propertyChanged ( const QMap< QString, int > & changes )

protectedpure virtual

This signal is emitted when a property is changed in the device.

Parameters

changes

the map describing the property changes that occurred in the device, keys are property name and values describe the kind of change done on the device property (added/removed/modified), it's one of the type Solid::Device::PropertyChange

propertyExists()

virtual bool Solid::Ifaces::GenericInterface::propertyExists ( const QString & key ) const

pure virtual

Tests if a property exist.

Parameters

key	the property name

Returns

true if the property exists in this device, false otherwise
