                     Map<String,String> properties)

Creates a driver with the specified name.

Parameters:

name - driver name

parents - optional parent drivers

manufacturer - device manufacturer

hwVersion - device hardware version

swVersion - device software version

behaviours - device behaviour classes

properties - properties for configuration of device behaviour classes

Method Detail

merge

public Driver merge(Driver other)

Description copied from interface: Driver

Merges the specified driver behaviours and properties into this one, giving preference to the other driver when dealing with conflicts.

Specified by:

merge in interface Driver

Parameters:

other - other driver

Returns:

merged driver

name

public String name()

Description copied from interface: Driver

Returns the driver name. This is expected to be a reverse-DNS, Java package-like name.

Specified by:

name in interface Driver

Returns:

driver name

manufacturer

public String manufacturer()

Description copied from interface: Driver

Returns the device manufacturer name.

Specified by:

manufacturer in interface Driver

Returns:

manufacturer name

hwVersion

public String hwVersion()

Description copied from interface: Driver

Returns the device hardware version.

Specified by:

hwVersion in interface Driver

Returns:

hardware version

swVersion

public String swVersion()

Description copied from interface: Driver

Returns the device software version.

Specified by:

swVersion in interface Driver

Returns:

software version

parent

public Driver parent()

Description copied from interface: Driver

Returns the parent driver from which this driver inherits behaviours and properties.

Specified by:

parent in interface Driver

Returns:

parent driver; null if driver has no parent

parents

public List<Driver> parents()

Description copied from interface: Driver

Returns all the parent drivers from which this driver inherits behaviours and properties.

Specified by:

parents in interface Driver

Returns:

list of parent drivers

behaviours

public Set<Class<? extends Behaviour>> behaviours()

Description copied from interface: Driver

Returns the set of behaviours supported by this driver. It reflects behaviours of only this driver and not its parent.

Specified by:

behaviours in interface Driver

Returns:

set of device driver behaviours

implementation

public Class<? extends Behaviour> implementation(Class<? extends Behaviour> behaviour)

Description copied from interface: Driver

Returns the implementation class for the specified behaviour. It reflects behaviours of only this driver and not its parent.

Specified by:

implementation in interface Driver

Parameters:

behaviour - behaviour interface

Returns:

implementation class

hasBehaviour

public boolean hasBehaviour(Class<? extends Behaviour> behaviourClass)

Description copied from interface: Driver

Indicates whether or not the driver, or any of its parents, support the specified class of behaviour.

Specified by:

hasBehaviour in interface Driver

Parameters:

behaviourClass - behaviour class

Returns:

true if behaviour is supported

createBehaviour

public <T extends Behaviour> T createBehaviour(DriverData data,
                                               Class<T> behaviourClass)

Description copied from interface: Driver

Creates an instance of behaviour primed with the specified driver data. If the current driver does not support the specified behaviour and the driver has parent, the request is delegated to the parent driver.

Specified by:

createBehaviour in interface Driver

Type Parameters:

T - type of behaviour

Parameters:

data - driver data context

behaviourClass - driver behaviour class

Returns:

behaviour instance

createBehaviour

public <T extends Behaviour> T createBehaviour(DriverHandler handler,
                                               Class<T> behaviourClass)

Description copied from interface: Driver

Creates an instance of behaviour primed with the specified driver handler. If the current driver does not support the specified behaviour and the driver has parent, the request is delegated to the parent driver.

Specified by:

createBehaviour in interface Driver

Type Parameters:

T - type of behaviour

Parameters:

handler - driver handler context

behaviourClass - driver behaviour class

Returns:

behaviour instance

keys

public Set<String> keys()

Description copied from interface: Annotations

Returns the set of keys for available annotations.

Specified by:

keys in interface Annotations

Returns:

annotation keys

value

Returns the set of annotations as map of key/value properties.

Specified by:

properties in interface Driver

Returns:

map of properties

getProperty

public String getProperty(String name)
